亚马逊AWS上安装Nginx(Linux,CentOS环境)

以前一直使用Apache服务器，但是在内存贵如油的AWS上，使用省内存的Nginx服务器应该是个不错的选择，它能降低我们很多成本。

关于AWS的linux实例安装请参考在亚马逊AWS上创建EC2的Linux(CentOS)实例

我们分以下五步，完成aws上nginx的架设。

1. 安装mysql
2. 安装nginx
3. 安装php
4. 配置php
5. 配置nginx
6. 测试安装结果

安装必要的库

# cd
# wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm
# rm -rf epel-release-6-8.noarch.rpm

1. 安装mysql

切换到root用户

su

安装mysql

# yum install mysql mysql-server

初始化mysql，具体参看在Linux(CentOS6)上搭建Apache2+Mysql5+PHP5开发环境的mysql安装部分。

1. 安装nginx

# yum install nginx

启动nginx，并且配置nginx开机启动

# /etc/init.d/nginx start
# chkconfig nginx on

3. 安装php

安装php及相关php的包

# yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml php-pear php-fpm

4. 配置php

# vi /etc/php.ini

找到#cgi.fix_pathinfo=1，在下面添加

cgi.fix_pathinfo=0

5. 配置nginx

vi /etc/nginx/conf.d/default.conf

更改如下

server {
    listen       80 default_server;
    server_name  _;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

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

    error_page  404              /404.html;
    location = /404.html {
        #root   /usr/share/nginx/html;
        root   /var/www/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;
        root   /var/www/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           /var/www/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$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;
    #}
}

6. 启动nginx

# /etc/rc.d/init.d/nginx restart
# chkconfig nginx on

7. 启动php-fpm

# /etc/rc.d/init.d/php-fpm restart
# chkconfig php-fpm on

8. 测试安装

在/var/www/html中添加info.php,访问 http://********/info.php
