CentOS 6.5 + Nginx 1.8.0 + PHP 5.6(with PHP-FPM) 负载均衡源码安装 之 （一）Nginx安装篇

yum -y install wget

yum -y install gcc gcc-c++ automake autoconf libtool make

cd /usr/local/src
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.37.tar.gz tar zxvf pcre-8.37.tar.gz
cd pcre-8.37
./configure
make
make install

cd /usr/local/src
wget http://zlib.net/zlib-1.2.8.tar.gz tar zxvf zlib-1.2.8.tar.gz
cd zlib-1.2.8
./configure
make
make install

cd /root
mkdir download
cd download

wget http://nginx.org/download/nginx-1.8.0.tar.gz[/code] 
6.解压、编译、安装（采用默认安装配置，但pcre的位置需要指定）

tar zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure --with-pcre=/usr/local/src/pcre-8.37
make
make install


最终nginx的安装路径信息为：

Configuration summary
+ using PCRE library: /usr/local/src/pcre-8.37
+ OpenSSL library is not used
+ using builtin md5 code
+ sha1 library is not found
+ using system zlib library

nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx configuration prefix: "/usr/local/nginx/conf"
nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"


7.我们测试运行下服务器

/usr/local/nginx/sbin/nginx


然后本地通过wget访问下：

cd ~
wget http://localhost[/code] 
访问结果如下，表示已经可以访问：

--2015-10-29 03:06:59--  http://localhost/ 正在解析主机 localhost... ::1, 127.0.0.1
正在连接 localhost|::1|:80... 失败：拒绝连接。
正在连接 localhost|127.0.0.1|:80... 已连接。
已发出 HTTP 请求，正在等待回应... 200 OK
长度：612 [text/html]
正在保存至: “index.html”

100%[======================================>] 612         --.-K/s   in 0s

2015-10-29 03:06:59 (54.4 MB/s) - 已保存 “index.html” [612/612])


我们也可以通过外面浏览器去访问这个虚拟机，直接在浏览器输入该虚拟机ip: http://192.168.168.131 （具体IP以自己虚拟机为准），应该会展示出下页面（若无法访问，参考最下面）：



8.以上虽然可以访问了，但每次需要手动去调用才执行，所以我们需要：

8.1.编写一个服务脚本，存放到/etc/init.d/nginx （/etc/init.d目录一般用于存放系统所有的服务程序），脚本内容如下：

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
#
# chkconfig:   - 85 15
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /usr/local/nginx/conf/nginx.conf
# pidfile:     /usr/local/nginx/logs/nginx.pid

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)

NGINX_CONF_FILE="/usr
b466
/local/nginx/conf/nginx.conf"

lockfile=/var/lock/subsys/nginx

start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}

stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}

restart() {
configtest || return $?
stop
start
}

reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}

force_reload() {
restart
}

configtest() {
$nginx -t -c $NGINX_CONF_FILE
}

rh_status() {
status $prog
}

rh_status_q() {
rh_status >/dev/null 2>&1
}

case "$1" in
start)
rh_status_q && exit 0
$1
;;
stop)
rh_status_q || exit 0
$1
;;
restart|configtest)
$1
;;
reload)
rh_status_q || exit 7
$1
;;
force-reload)
force_reload
;;
status)
rh_status
;;
condrestart|try-restart)
rh_status_q || exit 0
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac


然后给此脚本添加运行权限：

chmod +x /etc/init.d/nginx


测试此脚本（停止服务、启动服务、重启服务），成功后会打印“确定”字样：

service nginx stop
service nginx start
service nginx restart


8.2.将服务脚本注册为系统服务并随系统启动

chkconfig nginx on


到此，Nginx就已安装完毕并可提供服务了
