安装步骤:

  (系统要求:Linux 2.6+ 内核,本文中的Linux操作系统为CentOS 5.3,另在RedHat AS4上也安装成功)

  一、获取相关开源程序:

  1、【适用CentOS操作系统】利用CentOS Linux系统自带的yum命令安装、升级所需的程序库(RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包,进行安装):

sudo -s
LANG=C
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers

  2、【适用RedHat操作系统】 RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包(事先可通过类似“rpm -qa | grep libjpeg”的命令查看所需的RPM包是否存在,通常是“xxx-devel”不存在,需要安装)。RedHat可以直接利用CentOS的RPM包安装,以下是RPM包下载网址:

  ①、RedHat AS4 & CentOS 4

  http://mirrors.163.com/centos/4/os/i386/CentOS/RPMS/

  http://mirrors.163.com/centos/4/os/x86_64/CentOS/RPMS/

  ②、RedHat AS5 & CentOS 5

  http://mirrors.163.com/centos/5/os/i386/CentOS/

  http://mirrors.163.com/centos/5/os/x86_64/CentOS/

  ③、RPM包搜索网站

  http://rpm.pbone.net/

  http://www.rpmfind.net/

  ④、RedHat AS4 系统环境,通常情况下缺少的支持包安装:

wget http://blog.s135.com/soft/linux/nginx_php/imagick/imagick-2.2.2.tgz
 

二、安装PHP 5.2.10(FastCGI模式)

  1、编译安装PHP 5.2.10所需的支持库:

tar zxvf libiconv-1.13.tar.gz

cd libiconv-1.13/

./configure --prefix=/usr/local

make

make install

cd ../

tar zxvf libmcrypt-2.5.8.tar.gz

cd libmcrypt-2.5.8/

./configure

make

make install

/sbin/ldconfig

cd libltdl/

./configure --enable-ltdl-install

make

make install

cd ../../

tar zxvf mhash-0.9.9.9.tar.gz

tar zxvf mcrypt-2.6.8.tar.gz

cd mcrypt-2.6.8/

/sbin/ldconfig

./configure

make

make install

cd ../

--------------------------------------------------------------------------------

  2、编译安装MySQL 5.1.35

/usr/sbin/groupadd mysql

/usr/sbin/useradd -g mysql mysql

tar zxvf mysql-5.1.35.tar.gz

cd mysql-5.1.35/

./configure --prefix=/opt/modules/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=innobase

make && make install

chmod +w /opt/modules/mysql

chown -R mysql:mysql /opt/modules/mysql

cd ../

--------------------------------------------------------------------------------

  附:以下为附加步骤,如果你想在这台服务器上运行MySQL数据库,则执行以下两步。如果你只是希望让PHP支持MySQL扩展库,能够连接其他服务器上的MySQL数据库,那么,以下两步无需执行。

  ①、创建MySQL数据库存放目录

mkdir -p /data0/mysql/3306/data/

chown -R mysql:mysql /data0/mysql/

  ②、以mysql用户帐号的身份建立数据表:

/opt/modules/mysql/bin/mysql_install_db --basedir=/opt/modules/mysql --datadir=/data0/mysql/3306/data --user=mysql

  ③、创建my.cnf配置文件:

vi /data0/mysql/3306/my.cnf

  输入以下内容:

引用

[client]

default-character-set = utf8

port    = 3306

socket  = /tmp/mysql.sock

[mysql]

prompt="(\u:blog.s135.com:)[\d]> "

no-auto-rehash

[mysqld]

#default-character-set = utf8

user    = mysql

port    = 3306

socket  = /tmp/mysql.sock

basedir = /opt/modules/mysql

datadir = /data0/mysql/3306/data

open_files_limit    = 10240

back_log = 600

max_connections = 3000

max_connect_errors = 6000

table_cache = 614

external-locking = FALSE

max_allowed_packet = 32M

sort_buffer_size = 2M

join_buffer_size = 2M

thread_cache_size = 300

thread_concurrency = 8

query_cache_size = 32M

query_cache_limit = 2M

query_cache_min_res_unit = 2k

default-storage-engine = MyISAM

default_table_type = MyISAM

thread_stack = 192K

transaction_isolation = READ-COMMITTED

tmp_table_size = 246M

max_heap_table_size = 246M

long_query_time = 1

log_long_format

log-bin = /data0/mysql/3306/binlog

binlog_cache_size = 4M

binlog_format = MIXED

max_binlog_cache_size = 8M

max_binlog_size = 512M

expire_logs_days = 7

key_buffer_size = 256M

read_buffer_size = 1M

read_rnd_buffer_size = 16M

bulk_insert_buffer_size = 64M

myisam_sort_buffer_size = 128M

myisam_max_sort_file_size = 10G

myisam_max_extra_sort_file_size = 10G

myisam_repair_threads = 1

myisam_recover

skip-name-resolve

master-connect-retry = 10

slave-skip-errors = 1032,1062,126,1114,1146,1048,1396

server-id = 1

innodb_additional_mem_pool_size = 16M

innodb_buffer_pool_size = 2048M

innodb_data_file_path = ibdata1:1024M:autoextend

innodb_file_io_threads = 4

innodb_thread_concurrency = 8

innodb_flush_log_at_trx_commit = 2

innodb_log_buffer_size = 16M

innodb_log_file_size = 128M

innodb_log_files_in_group = 3

innodb_max_dirty_pages_pct = 90

innodb_lock_wait_timeout = 120

innodb_file_per_table = 0

[mysqldump]

quick

max_allowed_packet = 32M

  ④、创建管理MySQL数据库的shell脚本:

vi /data0/mysql/3306/mysql

  输入以下内容(这里的用户名admin和密码12345678接下来的步骤会创建):

view plaincopy to clipboardprint?

#!/bin/sh 

 

mysql_port=3306 

mysql_username="admin"

mysql_password="12345678"

 

function_start_mysql() 



    printf "Starting MySQL...\n"

    /bin/sh /opt/modules/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null & 



 

function_stop_mysql() 



    printf "Stoping MySQL...\n"

    /opt/modules/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown 



 

function_restart_mysql() 



    printf "Restarting MySQL...\n"

    function_stop_mysql 

    sleep 5 

    function_start_mysql 



 

function_kill_mysql() 



    kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}') 

    kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}') 



 

if [ "$1" = "start" ]; then 

    function_start_mysql 

elif [ "$1" = "stop" ]; then 

    function_stop_mysql 

elif [ "$1" = "restart" ]; then 

function_restart_mysql 

elif [ "$1" = "kill" ]; then 

function_kill_mysql 

else

    printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n"

fi

#!/bin/sh

mysql_port=3306

mysql_username="admin"

mysql_password="12345678"

function_start_mysql()

{

    printf "Starting MySQL...\n"

    /bin/sh /opt/modules/mysql/bin/mysqld_safe --defaults-file=/opt/modules/mysql/etc/${mysql_port}/my.cnf 2>&1 > /dev/null &

}

function_stop_mysql()

{

    printf "Stoping MySQL...\n"

    /opt/modules/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown

}

function_restart_mysql()

{

    printf "Restarting MySQL...\n"

    function_stop_mysql

    sleep 5

    function_start_mysql

}

function_kill_mysql()

{

    kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')

    kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')

}

if [ "$1" = "start" ]; then

    function_start_mysql

elif [ "$1" = "stop" ]; then

    function_stop_mysql

elif [ "$1" = "restart" ]; then

function_restart_mysql

elif [ "$1" = "kill" ]; then

function_kill_mysql

else

    printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n"

fi

  ⑤、赋予shell脚本可执行权限:

chmod +x /opt/modules/mysql/mysql

  ⑥、启动MySQL:

/opt/modules/mysql/mysql start

  ⑦、通过命令行登录管理MySQL服务器(提示输入密码时直接回车):

/opt/modules/mysql/bin/mysql -u root -p -S /tmp/mysql.sock

  ⑧、输入以下SQL语句,创建一个具有root权限的用户(admin)和密码(12345678):

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';

  ⑨、(可选)停止MySQL:

/opt/modules/mysql/mysql stop

--------------------------------------------------------------------------------

安装GD

  3、编译安装PHP(FastCGI模式)

tar zxvf php-5.2.10.tar.gz

gzip -cd php-5.2.10-fpm-0.5.11.diff.gz | patch -d php-5.2.10 -p1

cd php-5.2.10/

./configure --prefix=/opt/modules/php --with-config-file-path=/opt/modules/php/etc --with-mysql=/opt/modules/mysql --with-mysqli=/opt/modules/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap --without-pear

make ZEND_EXTRA_LIBS='-liconv'

make install

cp php.ini-dist /opt/modules/php/etc/php.ini

cd ../

--------------------------------------------------------------------------------

  4、编译安装PHP5扩展模块

tar zxvf memcache-2.2.5.tgz

cd memcache-2.2.5/

/opt/modules/php/bin/phpize

./configure --with-php-config=/opt/modules/php/bin/php-config

make

make install

cd ../

tar jxvf eaccelerator-0.9.5.3.tar.bz2

cd eaccelerator-0.9.5.3/

/opt/modules/php/bin/phpize

./configure --enable-eaccelerator=shared --with-php-config=/opt/modules/php/bin/php-config

make

make install

cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz

cd PDO_MYSQL-1.0.2/

/opt/modules/php/bin/phpize

./configure --with-php-config=/opt/modules/php/bin/php-config --with-pdo-mysql=/opt/modules/mysql

make

make install

cd ../

tar zxvf ImageMagick.tar.gz

cd ImageMagick-6.5.1-2/

./configure

make

make install

cd ../

tar zxvf imagick-2.2.2.tgz

cd imagick-2.2.2/

/opt/modules/php/bin/phpize

./configure --with-php-config=/opt/modules/php/bin/php-config

make

make install

cd ../

  5、修改php.ini文件

  手工修改:查找/opt/modules/php/etc/php.ini中的extension_dir = "./"

  修改为extension_dir = "/opt/modules/php/lib/php/extensions/no-debug-non-zts-20060613/"

  并在此行后增加以下几行,然后保存:

  extension = "memcache.so"

  extension = "pdo_mysql.so"

  extension = "imagick.so"

  再查找output_buffering = Off

  修改为output_buffering = On

  自动修改:若嫌手工修改麻烦,可执行以下shell命令,自动完成对php.ini文件的修改:

sed -i 's#extension_dir = "./"#extension_dir = "/opt/modules/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /opt/modules/php/etc/php.ini

sed -i 's#output_buffering = Off#output_buffering = On#' /opt/modules/php/etc/php.ini

sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /opt/modules/php/etc/php.ini

  6、配置eAccelerator加速PHP:

mkdir -p /opt/modules/eaccelerator_cache

vi /opt/modules/php/etc/php.ini

  按shift+g键跳到配置文件的最末尾,加上以下配置信息:

引用

[eaccelerator]

zend_extension="/opt/modules/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"

eaccelerator.shm_size="64"

eaccelerator.cache_dir="/opt/modules/eaccelerator_cache"

eaccelerator.enable="1"

eaccelerator.optimizer="1"

eaccelerator.check_mtime="1"

eaccelerator.debug="0"

eaccelerator.filter=""

eaccelerator.shm_max="0"

eaccelerator.shm_ttl="3600"

eaccelerator.shm_prune_period="3600"

eaccelerator.shm_only="0"

eaccelerator.compress="1"

eaccelerator.compress_level="9"

--------------------------------------------------------------------------------

  7、创建www用户和组,以及供blog.s135.com和http://www.s135.com/两个虚拟主机使用的目录:

/usr/sbin/groupadd www

/usr/sbin/useradd -g www www

mkdir -p /data0/htdocs/blog

chmod +w /data0/htdocs/blog

chown -R www:www /data0/htdocs/blog

mkdir -p /data0/htdocs/www

chmod +w /data0/htdocs/www

chown -R www:www /data0/htdocs/www

  8、创建php-fpm配置文件(php-fpm是为PHP打的一个FastCGI管理补丁,可以平滑变更php.ini配置而无需重启php-cgi):

  在/opt/modules/php/etc/目录中创建php-fpm.conf文件:

rm -f /opt/modules/php/etc/php-fpm.conf

vi /opt/modules/php/etc/php-fpm.conf

  输入以下内容(如果您安装 Nginx + PHP 用于程序调试,请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>,以便显示PHP错误信息,否则,Nginx 会报状态为500的空白错误页):view plaincopy to clipboardprint?

</configuration>  9、启动php-cgi进程,监听127.0.0.1的9000端口,进程数为200(如果服务器内存小于3GB,可以只开启64个进程),用户为www:

ulimit -SHn 51200

/opt/modules/php/sbin/php-fpm start

  注:/opt/modules/php/sbin/php-fpm还有其他参数,包括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件使用reload。

--------------------------------------------------------------------------------

  三、安装Nginx 0.7.61

  1、安装Nginx所需的pcre库:

tar zxvf pcre-7.9.tar.gz

cd pcre-7.9/

./configure

make && make install

cd ../

  2、安装Nginx

tar zxvf nginx-0.7.61.tar.gz

cd nginx-0.7.61/

./configure --user=www --group=www --prefix=/opt/modules/nginx --with-http_stub_status_module --with-http_ssl_module

make && make install

cd ../

  3、创建Nginx日志目录

mkdir -p /data1/logs

chmod +w /data1/logs

chown -R www:www /data1/logs

  4、创建Nginx配置文件

  ①、在/opt/modules/nginx/conf/目录中创建nginx.conf文件:

rm -f /opt/modules/nginx/conf/nginx.conf

vi /opt/modules/nginx/conf/nginx.conf

  输入以下内容:

引用

    location ~ .*\.(php|php5)?$

    {    

      #fastcgi_pass  unix:/tmp/php-cgi.sock;

      fastcgi_pass  127.0.0.1:9000;

      fastcgi_index index.php;

      include fcgi.conf;

    }

  

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$

    {

      expires      30d;

    }

    location ~ .*\.(js|css)?$

    {

      expires      1h;

    }  

    log_format  access  '$remote_addr - $remote_user [$time_local] "$request" '

              '$status $body_bytes_sent "$http_referer" '

              '"$http_user_agent" $http_x_forwarded_for';

    access_log  /opt/data/logs/access.log  access;

      }

  server

  {

    listen       80;

    server_name  http://www.ruanzhong1.com;/
    index index.html index.htm index.php;

    root  /opt/ruanz1-data;

    location ~ .*\.(php|php5)?$

    {    

      #fastcgi_pass  unix:/tmp/php-cgi.sock;

      fastcgi_pass  127.0.0.1:9000;

      fastcgi_index index.php;

      include fcgi.conf;

    }

    log_format  wwwlogs  '$remote_addr - $remote_user [$time_local] "$request" '

               '$status $body_bytes_sent "$http_referer" '

               '"$http_user_agent" $http_x_forwarded_for';

    access_log  /opt/data/logs/wwwlogs.log  wwwlogs;

  }

  server

  {

    listen  80;

    server_name  status.ruanzhong.com;

    location / {

    stub_status on;

    access_log   off;

    }

  }

}

  ②、在/opt/modules/nginx/conf/目录中创建fcgi.conf文件:

vi /opt/modules/nginx/conf/fcgi.conf

  输入以下内容:

引用

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;

fastcgi_param  SERVER_SOFTWARE    nginx;

fastcgi_param  QUERY_STRING       $query_string;

fastcgi_param  REQUEST_METHOD     $request_method;

fastcgi_param  CONTENT_TYPE       $content_type;

fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;

fastcgi_param  REQUEST_URI        $request_uri;

fastcgi_param  DOCUMENT_URI       $document_uri;

fastcgi_param  DOCUMENT_ROOT      $document_root;

fastcgi_param  SERVER_PROTOCOL    $server_protocol;

fastcgi_param  REMOTE_ADDR        $remote_addr;

fastcgi_param  REMOTE_PORT        $remote_port;

fastcgi_param  SERVER_ADDR        $server_addr;

fastcgi_param  SERVER_PORT        $server_port;

fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect

fastcgi_param  REDIRECT_STATUS    200;

  5、启动Nginx

ulimit -SHn 51200

/opt/modules/nginx/sbin/nginx

--------------------------------------------------------------------------------

  四、配置开机自动启动Nginx + PHP

vi /etc/rc.local

  在末尾增加以下内容:

引用

ulimit -SHn 51200

/opt/modules/php/sbin/php-fpm start

/opt/modules/nginx/sbin/nginx

--------------------------------------------------------------------------------

  五、优化Linux内核参数

vi /etc/sysctl.conf

  在末尾增加以下内容:

引用

# Add

net.ipv4.tcp_max_syn_backlog = 65536

net.core.netdev_max_backlog =  32768

net.core.somaxconn = 32768

net.core.wmem_default = 8388608

net.core.rmem_default = 8388608

net.core.rmem_max = 16777216

net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0

net.ipv4.tcp_synack_retries = 2

net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1

#net.ipv4.tcp_tw_len = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000

net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30

#net.ipv4.tcp_keepalive_time = 120

net.ipv4.ip_local_port_range = 1024  65535

  使配置立即生效:

/sbin/sysctl -p

--------------------------------------------------------------------------------

  六、在不停止Nginx服务的情况下平滑变更Nginx配置

  1、修改/opt/modules/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确:

/opt/modules/nginx/sbin/nginx -t

  如果屏幕显示以下两行信息,说明配置文件正确:

  the configuration file /opt/modules/nginx/conf/nginx.conf syntax is ok

  the configuration file /opt/modules/nginx/conf/nginx.conf was tested successfully

  2、这时,输入以下命令查看Nginx主进程号:

ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'

  屏幕显示的即为Nginx主进程号,例如:

  6302

  这时,执行以下命令即可使修改过的Nginx配置文件生效:

kill -HUP 6302

  或者无需这么麻烦,找到Nginx的Pid文件:

kill -HUP `cat /opt/modules/nginx/nginx.pid`

--------------------------------------------------------------------------------

  七、编写每天定时切割Nginx日志的脚本

  1、创建脚本/opt/modules/nginx/sbin/cut_nginx_log.sh

vi /opt/modules/nginx/sbin/cut_nginx_log.sh

  输入以下内容:

引用

#!/bin/bash

# This script run at 00:00

# The Nginx logs path

logs_path="/opt/modules/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/

mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log

kill -USR1 `cat /opt/modules/nginx/nginx.pid`

  2、设置crontab,每天凌晨00:00切割nginx访问日志

crontab -e

  输入以下内容:

引用

00 00 * * * /bin/bash  /opt/modules/nginx/sbin/cut_nginx_log.sh
