Centos6.6用yum快速安装LA（N）MP

本文主要介绍在CentOS6.6下用yum快速搭建LAMP或LNMP环境


基本流程：

1.安装apche或nginx
2.安装mysql
3.安装php
4.测试环境

流程一：安装apache或nginx

1）关闭SELINUX

修改配置文件，重启服务后永久生效。
sed -i 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
命令行设置立即生效。
setenforce 0

网易官方源
centos6.x
cd /etc/yum.repos.d/
mv CentOS-Base.repo CentOS-Base.repo.$(date +%F)
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo yum clean all
yum makecache

2）安装Apache：

yum -y install httpd
yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql
/etc/init.d/httpd start
netstat -tnlp|grep 80

安装nginx：
Centos6系统库中默认是没有nginx的rpm包的，所以我们需要先更新下rpm依赖库
1）使用yum安装nginx，安装nginx库

rpm -Uvh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm 2）使用下面命令安装nginx
yum -y install nginx
[root@localhost ~]# nginx -v

nginx version: nginx/1.14.0
3）启动nginx
/etc/init.d/nginx start 或 service nginx start
4 ) 防火墙允许通过80端口
vim /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
/etc/init.d/iptables restart

流程二：安装mysql

1）安装Mysql，先更新yum源。yum源下载地址，根据自己需要的版本选择相应的源 https://dev.mysql.com/downloads/repo/yum/ 2）这里版本是6.x系列的，所以选择linux 6 下载
wget https://repo.mysql.com//mysql57-community-release-el6-11.noarch.rpm 3）安装mysql的yum源
rpm -Uvh mysql57-community-release-el6-11.noarch.rpm 或 yum -y localinstall mysql57-community-release-el6-11.noarch.rpm
4）查看mysql源是否成功
[root@localhost yum.repos.d]# ls /etc/yum.repos.d/|grep mysql
mysql57-community-release-el6-11.noarch.rpm
mysql-community.repo
mysql-community-source.repo
5)安装mysql

yum -y install mysql-community-server
[root@localhost ~]# mysql -V
mysql Ver 14.14 Distrib 5.7.22, for Linux (x86_64) using EditLine wrapper
6）开启mysql，并更改默认密码
/etc/init.d/mysqld start
netstat -tnlp |grep 3306
chkconfig mysqld on
[root@localhost yum.repos.d]# grep 'temporary password' /var/log/mysqld.log
2018-05-10T22:59:11.434638Z 1 [Note] A temporary password is generated for root@localhost: OScMFRu&j75Q
mysql -uroot -p"OScMFRu&j75Q"
ALTER USER 'root'@'localhost' IDENTIFIED BY 'ywxi123';
mysql -uroot -p"ywxi123"
7）防火墙允许通过3306端口
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
service iptables restart

流程三：安装php

1）更新yum源

rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm 2）安装PHP

yum -y install --enablerepo=remi --enablerepo=remi-php56 php php-bcmath php-opcache php-devel php-mbstring php-mcrypt php-mysqlnd php-gd php-xml php-memcache php-redis php-fpm php-mysql php-common php-mssql
3）配置php.ini文件，关闭php信息头
sed 's#expose_php = On#expose_php = Off#g' /etc/php.ini -i
[root@localhost html]# php -v
PHP 5.6.36 (cli) (built: Apr 25 2018 10:11:47)
4）启动php，并开机自启
/etc/init.d/php-fpm start
chkconfig php-fpm on

流程四：环境测试

1）LNMP环境测试准备
编辑/etc/nginx/conf.d/default.conf，在所支持的主页面格式中添加php格式的主页，类似如下：
[root@localhost conf.d]# cat default.conf
server {
listen 80;
server_name localhost;

#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;

location / {
root /usr/share/nginx/html;
index index.php index.html index.htm;
}

#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1; #}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html/$fastcgi_script_name;
include fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}

[root@localhost html]# cat /usr/share/nginx/html/index.php
<?php
$conn=mysql_connect('127.0.0.1','root','ywxi123');
if ($conn){
echo "LNMP platform connect to mysql is successful!";
}else{
echo "LNMP platform connect to mysql is failed!";
}
phpinfo();
?>
chown -R nginx.nginx /usr/share/nginx/html/ http://192.168.1.22/index.php 访问到如下页面证明LNMP环境搭建成功



2）LAMP环境测试准备
/etc/init.d/nginx stop
/etc/init.d/httpd start
[root@localhost html]# cat /var/www/html/index.php

<?php
$conn=mysql_connect('127.0.0.1','root','ywxi123');
if ($conn){
echo "LAMP platform connect to mysql is successful!";
}else{
echo "LAMP platform connect to mysql is failed!";
}
phpinfo();
?>
chown -R apache.apache /var/www/html http://192.168.1.22/index.php 访问到如下页面证明LAMP环境搭建成功
