nginx安装并配置实现端口转发

1、将nginx程序包上传至服务器,我这里使用的是nginx-1.21.6.tar.gz
2、解压nginx

tar -zxvf nginx-1.21.6.tar.gz

3、解压后会在当前目录下生成一个nginx-1.21.6目录
4、进入该目录,执行 --with-stream

./configure --prefix=安装路径 --with-stream     标红部分为必加,不加不支持tcp转发

5、运行命令后可能会出现如下错误,这表示你的服务器上没有pcre 和 pcre-devel和zlib-devel这3 个包,通过yum命令进行安装

​    yum -y install pcre

​    yum -y install pcre-devel

​    yum -y install zlib-devel

6、再次执行第四步中的命令

7、执行命令进行安装

make && make install

8、到这里nginx已经安装好了,接下来进行nginx.conf文件的配置

    配置文件路径:/你的安装路径/nginx/conf/nginx.conf

9、编辑配置文件,如下为nginx.conf 默认内容,在修改前请备份该文件

cp nginx.conf nginx_bak.conf
#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    wor{er_connections  1024;
}
}

http {
    include       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  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;
"nginx.conf" 117L, 2656C                                                                             1,0-1        顶ç«
    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   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           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$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;
        #}
    }

    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

10、在配置文件中增加以下内容

stream {     --stream部分与http部分平级
   #这两段实现的是10.170.12.159:19013端口通过本地服务器的22222端口转发出去
   #其中下面的两处mysqltest可以自己起名,但要保证名称相同
   upstream mysqltest {
     server 10.110.111.159:19013;
   }
   server {
   listen 22222;
   proxy_pass mysqltest;
   }
}

11、增加内容后的nginx.conf明细内容如下,其中红框部分为本次新增内容,我在这里添加了两个如需转发更多端口在stream中继续增加即可,用于进行端口转发(本配置文件内容仅支持端口转发功能)

12、启动nginx

cd /home/collect/nginx/sbin
./nginx -c /home/collect/nginx/conf/nginx.conf

至此端口转发已完成,可以使用了
