在Ubuntu 12.4 下安装 nginx, MySQL, PHP

LNMP是时下很流行的网站配置，我在配置蝉大师服务器的时候顺带把经验做个分享，蝉大师的网址是：http://www.ddashi.com/

1、第一步，跟新apt-get

输入：

sudo apt-get update

2、第二步，安装Mysql

输入：

sudo apt-get install mysql-server php5-mysql

安装过程中mysql会要求你给数据库设定密码，输入两次后继续……

输入：

sudo mysql_install_db

继续输入：

sudo /usr/bin/mysql_secure_installation

会提示你输入刚刚设定的mysql密码，输入即可

问你是否要更改密码，输入N即可

接下来Mysql会提示几个问题，填入下边对应的y或n即可

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL 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] y                                            
 ... Success!

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] y
... Success!

By default, MySQL 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] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

3、第三步、安装Nginx

依次输入:

echo "deb http://ppa.launchpad.net/nginx/stable/ubuntu $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/nginx-stable.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C300EE8C
sudo apt-get update
sudo apt-get install nginx

启动nginx:

sudo service nginx start

这时候你可以访问你的域名或IP地址来看看Nginx是否工作了

输入如下命令可以知道你的IP：

ifconfig eth0 | grep inet | awk '{ print $2 }'

4、第四步，安装PHP

sudo apt-get install php5-fpm

配置PHP：

sudo nano /etc/php5/fpm/php.ini

找到, cgi.fix_pathinfo=1, 把1改为0即可，如下：

cgi.fix_pathinfo=0

接着：

sudo nano /etc/php5/fpm/pool.d/www.conf

找到, listen = 127.0.0.1:9000, 把 127.0.0.1:9000 改成 /var/run/php5-fpm.sock.

listen = /var/run/php5-fpm.sock

保存退出，启动PHP

sudo service php5-fpm restart

配置Nginx

sudo nano /etc/nginx/sites-available/default

启用PHP，绑定目录和index文件

[...]
server {
        listen   80;
     

        root /var/www;
        index index.php index.html index.htm;

        server_name example.com;

        location / {
                try_files $uri $uri/ /index.html;
        }

        error_page 404 /404.html;

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
              root /usr/share/nginx/www;
        }

        # pass the PHP scripts to FastCGI server listening on the php-fpm socket
        location ~ .php$ {
                try_files $uri =404;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
                
        }

}
[...]

可以了，建个文件试试吧：

sudo nano /var/www/info.php
