## nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1

安装

yum install http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum -y install nginx
yum -y install php php-common php-iconv php-mbstring php-fpm php-mysql php-pecl-ssh2

简单配置

nginx的配置文件在/etc/nginx目录下

基本规则

  1. 修改路径root or alias
  2. 设置php
  3. 防火墙(开放端口80)
    1
    2
    iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
    service iptables save
  4. 启动

    ## 自启动
    chkconfig php-fpm on
    chkconfig nginx on
    ## 启动服务
    service php-fpm restart
    service nginx restart

使用域名+端口配置

例如: www.baidu.com, www.baidu.com:8080
需要更多的域名和端口

## /etc/nginx/conf.d/dev.game.com.conf
## 访问方式: dev.game.com
server {
    listen       80; 
    server_name  dev.game.com;

    location / { 
        root   /data/hero/server/php;
        index  index.php index.html index.htm;
        ## 显示目录
        autoindex on;
        autoindex_exact_size off;
        autoindex_localtime on;
    }   

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

    location ~ \.php$ {
        root           /data/hero/server/php;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_connect_timeout 75; 
        fastcgi_read_timeout 1200;
        fastcgi_send_timeout 1200;
        include        fastcgi_params;
    }
}

使用虚拟目录配置

例如: learn.mingilin.com/rust, learn.mingilin.com/centos_daily
同一个域名和端口下可以建立多个网站

## /etc/nginx/conf.d/default.conf
server {
    listen       80; 
    server_name  localhost;
    include /etc/nginx/conf.d/vhost.d/*.conf;
}

location /hero/server/php {
    root   /data;
    ## alias /data/hero/server/php;
    index  index.php index.html index.htm;
    location ~ \.php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_connect_timeout 75; 
        fastcgi_read_timeout 1200;
        fastcgi_send_timeout 1200;
        include        fastcgi_params;
    }   
}

## /etc/nginx/conf.d/vhost.d/eat.conf
## 访问方式: localhost/eat
location /eat {
    root    /data/help_doc;
    index   index.php index.html index.htm;
    location ~\.php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }   
}

$document_root的设置非常关键, 否则php无法使用

http/https代理

upstream proxy_server {
    server localhost:8081;
    server localhost:8082;
    ip_hash;
}

server {
    listen      8080;
    location / {
        proxy_pass http://proxy_server;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

        proxy_max_temp_file_size 0;
        proxy_connect_timeout      90;
        proxy_send_timeout         90;
        proxy_read_timeout         90;
        proxy_buffer_size          4k;
        proxy_buffers              4 32k;
        proxy_busy_buffers_size    64k;
        proxy_temp_file_write_size 64k;
    }
}

采用ip_hash的轮询方法,每个ip在一定时间内会被固定的后端服务器
可以解决session共享问题

tcp代理

需要编译时加入--with-stream参数, 使用nginx -V查询

stream {
    upstream mysqld {

    }
    server {
        listen      8083;
        proxy_pass mysqld;
    }
}

stream和http是同级目录

    keepalive_timeout  65;

    include d:/nginx/conf/server/*.conf;
    #gzip  on;

}

include d:/nginx/conf/tcp/*.conf;

Windows配置

  1. 配置与Linux基本相同, 要特殊处理下启动

  2. 要使用特殊的工具来执行启动

    taskkill /F /IM nginx.exe >nul
    echo Stopping PHP FastCGI...
    taskkill /F /IM php-cgi.exe >nul
    exit

  3. 也可以使用nssm注册为服务启动/关闭

  4. 在erl帮助文档的时候,需要手动跳转下
