Nginx安装及 nginx_upstream_check_module（nginx主动健康检查模块）和nginx-upsync-module（nginx服务发现模块）安装

不喜欢写作的厨师不是个好程序猿

1.在 /opt/下安装，进入/opt/目录

 cd /opt/

获取nginx-1.19.6.tar.gz安装包

 wget http://nginx.org/download/nginx-1.19.6.tar.gz

2.下载对应模块 nginx_upstream_check_module：nginx主动健康检查模块和nginx-upsync-module：nginx服务发现模块

普通地址： git clone  https://github.com/xiaokai-wang/nginx_upstream_check_module.git
加速地址： git clone https://github.com.cnpmjs.org/xiaokai-wang/nginx_upstream_check_module.git 
普通地址： git clone https://github.com/weibocom/nginx-upsync-module.git
加速地址： git clone https://github.com.cnpmjs.org/weibocom/nginx-upsync-module.git

 git clone https://github.com.cnpmjs.org/weibocom/nginx-upsync-module.git
 git clone https://github.com.cnpmjs.org/xiaokai-wang/nginx_upstream_check_module.git

3.解压nginx安装包并进入对应目录

 tar -xf nginx-1.19.6.tar.gz && cd nginx-1.19.6

4.打补丁，安装，编译

 patch -p1 < /opt/nginx_upstream_check_module/check_1.12.1+.patch
 ./configure --add-module=/opt/nginx_upstream_check_module --add-module=/opt/nginx-upsync-module
 make
 make install

5.确认配置

 /usr/local/nginx/sbin/nginx -V

6.配置全局

 ln -s /usr/local/nginx/sbin/nginx /usr/local/bin/nginx

7.检查nginx.conf是否有语法错误

 nginx -t

8.启动nginx

 nginx

9.配置文件

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

    upstream web-test {
        server 106.13.224.166:8500        weight=5;
        server 106.13.224.166:8310        weight=5;
        server 106.13.224.166:8320        weight=5;
        check interval=3000 rise=2 fall=5 timeout=1000 type=http;
        check_http_send "HEAD / HTTP/1.0\r\n\r\n";
        check_http_expect_alive http_2xx http_3xx;
    }

    upstream test {
        server 127.0.0.1:11111;
        upsync 106.13.224.166:8500/v1/kv/upstreams/test/ upsync_timeout=6m upsync_interval=500ms upsync_type=consul strong_dependency=off;
        upsync_dump_path /usr/local/nginx/conf/servers/servers_test.conf;
        include /usr/local/nginx/conf/servers/servers_test.conf;
         check interval=1000 rise=2 fall=2 timeout=3000 type=http default_down=false;
         check_http_send "HEAD / HTTP/1.0\r\n\r\n";
         check_http_expect_alive http_2xx http_3xx;
    }

    upstream eureka {
        server 106.12.83.94:9901 weight=1 fail_timeout=10 max_fails=3;
    }

    server {
        listen       8080;

        location = /test {
            proxy_pass http://test;
        }

        location = /eureka {
            proxy_pass http://eureka;
        }

        location = /upstream_show {
            upstream_show;
        }

        location /web-test {
            proxy_pass http://web-test;
        }

        location /status {
            check_status;
        }

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

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

其中/usr/local/nginx/conf/servers/servers_test.conf 目录及文件要新建

10.添加服务

curl -X PUT http://106.13.224.166:8500/v1/kv/upstreams/test/106.12.83.94:9901

添加服务后访问http://IP:8080/status 可以看到服务注册成功。

删除服务：

curl -X DELETE http://106.13.224.166:8500/v1/kv/upstreams/testr/106.12.83.94:9901

11.问题

版本问题：

xiaokai-wang 分支兼容 nginx-upsync-module 模块【推荐】，1.12.1 的补丁可以用于 1.16.1
https://github.com/xiaokai-wang/nginx_upstream_check_module.git
yaoweibin 分支不兼容 nginx-upsync-module 模块，但补丁更新较快
https://github.com/yaoweibin/nginx_upstream_check_module.git

找不到对应servers （配置文件中没有加 server 127.0.0.1:11111;导致）

upstream test {

server 127.0.0.1:11111;

upsync 106.13.224.166:8500/v1/kv/upstreams/test/ upsync_timeout=6m upsync_interval=500ms upsync_type=consul strong_dependency=off;

upsync_dump_path /usr/local/nginx/conf/servers/servers_test.conf;

include /usr/local/nginx/conf/servers/servers_test.conf;

check interval=1000 rise=2 fall=2 timeout=3000 type=http default_down=false;

check_http_send "HEAD / HTTP/1.0\r\n\r\n";

check_http_expect_alive http_2xx http_3xx;

}

12.附录

测试配置文件：${Nginx}/sbin/nginx -t

启动命令：${Nginx}/sbin/nginx

停止命令：${Nginx}/sbin/nginx -s stop/quit

重启命令：${Nginx}/sbin/nginx -s reload

查看进程命令：ps -ef | grep nginx

平滑重启：kill -HUP [Nginx主进程号(即ps命令查到的PID)]
