Ubuntu配置nginx、mysql、php

1. 配置源，更新一下

sudo apt-get update

sudo apt-get upgrade

安装vim

sudo apt-get install vim

2. 安装nginx

sudo apt-get install nginx

3. 安装mysql

切换管理员权限
sudo su
安装mysql服务器端和客户端

apt-get install mysql-server mysql-client，
安装过程中会提示输入密码，请按要求输入即可。

4. 安装PHP5

apt-get install php5-fpm

5.编辑Nginx配置文件

Nginx优化

cd /etc/nginx/

vim nginx.conf
- 将第二行改成你的cpu核心数，例如你的服务器是双核cpu，那就填2
  worker_processes 4;

配置 Nginx 支持 PHP

cd sites-available、
cp default php、
vim php

server {
    #listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default ipv6only=on; ## listen for ipv6

    #root /usr/share/nginx/www;
    #如果是服务器上，请放到/var/www .

    #加上index.php, 这样会默认执行index.php
    index index.html index.htm index.php;

    # Make site accessible from http://localhost/
    #服务器上改成自己的域名
    server_name localhost;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to index.html
        try_files $uri $uri/ /index.html;
        # Uncomment to enable naxsi on this location
        # include /etc/nginx/naxsi.rules
    }

    #使用php5-fpm解析php，其实也就是让nginx支持php
    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        #   # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
        #
        #   # With php5-cgi alone:
        #    fastcgi_pass 127.0.0.1:9000;
        #   # With php5-fpm:
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }
}

使Nginx配置文件生效

cd ..
cd sites-enabled
rm default
ln -s /etc/nginx/sites-available/php /etc/nginx/sites-enabled/php

放置PHP探针文件phpinfo.php

cd /var/www
vim info.php

<?php
    phpinfo();

重启Nginx和php5-fpm
```
service nginx restart
service php5-fpm restart
```
访问http://127.0.0.1/info.php,如果看到phpinfo信息，那就是成功了。

** 6.安装PHP的相关模块**

#模块查询
apt-cache search php5
#常见模块
#php5-mysql php5-curl php5-gd php5-intl php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl
    
#以下为必装模块：
