nginx反向代理mysql

公司有一个公网ip,那台服务器上装的nginx, mysql装在公司另外一台服务器上假设ip为 192.168.17.131,我想利用公网ip的3308端口去访问内网电脑上mysql,就可以利用nginx 进行代理。

nginx1.9及以上才可以支持tcp协议

在nginx安装路径/nginx-1.9.0/conf 目录下 nginx.conf 文件添加如下代码,

注意下面http中的配置： include /etc/nginx/conf.d/http*.conf;

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

[root@localhost nginx]# pwd /etc/nginx [root@localhost nginx]# ll 总用量 32 drwxr-xr-x. 2 root root 82 3月 18 16:09 conf.d -rw-r--r--. 1 root root 1007 7月 11 2017 fastcgi_params -rw-r--r--. 1 root root 2837 7月 11 2017 koi-utf -rw-r--r--. 1 root root 2223 7月 11 2017 koi-win -rw-r--r--. 1 root root 3957 7月 11 2017 mime.types lrwxrwxrwx. 1 root root 29 7月 21 2017 modules -> ../../usr/lib64/nginx/modules -rw-r--r-- 1 root root 894 3月 18 17:51 nginx.conf -rw-r--r--. 1 root root 636 7月 11 2017 scgi_params -rw-r--r--. 1 root root 664 7月 11 2017 uwsgi_params -rw-r--r--. 1 root root 3610 7月 11 2017 win-utf [root@localhost nginx]# cat nginx.conf user nginx; worker_processes 1; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; # include /etc/nginx/conf.d/*.conf; include /etc/nginx/conf.d/http*.conf; } #添加Nginx stream支持，代理TCP连接 stream { upstream mysql { hash $remote_addr consistent; server 192.168.17.131:3306 max_fails=3 fail_timeout=30s; } server { listen 3308; proxy_connect_timeout 30s; proxy_pass mysql; } } [root@localhost nginx]#

如果不实现负载均衡，操作更加简单，下面代码是实现用不同端口代理不同mysql的配置.

1 2 3 4 5 6 7

stream { server { listen 3308; proxy_connect_timeout 30s; proxy_pass 192.168.17.131:3306; } }

 

优化配置

在 nginx.conf 配置文件中，配置如下：

注意下面http中的配置： include /etc/nginx/conf.d/http*.conf;

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

[root@localhost nginx]# cat nginx.conf user nginx; worker_processes 1; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; # include /etc/nginx/conf.d/*.conf; include /etc/nginx/conf.d/http*.conf; } #添加Nginx stream支持，代理TCP连接 stream { include /etc/nginx/conf.d/*-stream.conf; } [root@localhost nginx]#

在 /etc/nginx/conf.d 配置：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

[root@localhost conf.d]# pwd /etc/nginx/conf.d [root@localhost conf.d]# ll 总用量 8 -rw-r--r--. 1 root root 1299 7月 26 2017 default.conf.bak -rw-r--r-- 1 root root 241 3月 18 19:19 mysql-stream.conf [root@localhost conf.d]# cat mysql-stream.conf upstream mysql { hash $remote_addr consistent; server 192.168.17.131:3306 max_fails=3 fail_timeout=30s; } server { listen 3308; proxy_connect_timeout 30s; proxy_pass mysql; } [root@localhost conf.d]#
