针对PHP的动静分离
LAMP环境Nginx处理静态页面请求，在server {};段中加入[root@nginx php5]#vim /usr/local/httpd/conf/nginx.conf
location ~ .*\.(gifiglipeglbmp|swf)$ {
root html;
index index.html index.htm;
};[root@nginx php5]#vim /usr/local/httpd/conf/nginx.conf
server {
.....
location ~ \.php$ {
proxy_ pass http://192.168.9.237:8080; //LAMP的IP地址
......开启两台Linux虚拟机，一台配置Nginx，一台配置LANM架构，客户端访问nginx网页时Nginx服务处理静态访问信息，LAMP处理动态访问信息，

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): //询问是否给root用户设置密码，直接回车
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y //是否设置密码，输入y确认
New password: //输入密码
Re-enter new password: //再次输入密码
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] n //询问是否删除匿名用户，输入n，不删除
... skipping.
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n //询问是否拒绝root用户远程登录，输入n，不拒绝
... skipping.
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] n //询问是否删除测试数据库，输入n，不删除
... skipping.
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y //询问是否重新加载数据库，输入y，重新加载
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB! //完成设置[root@localhost ~]# yum -y install php //安装php服务
