nginx 健康检查配置

nginx 配置

upstream test {
 server   127.0.0.1:8001 max_fails=2 fail_timeout=30s;
 server   127.0.0.1:8002 max_fails=2 fail_timeout=30s;
}
    server {
        listen   8888;
        location / {
                proxy_pass   http://test ;
                # 配置debug模式的错误信息，用于查看详细的报错信息，默认是没debug功能的
error_log /Users/opt/nginx/logs/error.log debug;
}
}

debug模式开始方式
在 nginx 解压包中运行该命令
./configure --prefix=/usr/local/nginx --with-debug --with-http_ssl_module

make & make install
说明：

• –prefix=/usr/local/nginx 设置新编译的输出目录
• –with-debug 开启debug功能

当需要配置https的时候也是这个流程，默认是没有SSL 那个模块的，也得 --with-XXX（具体模块名忘了）这样重新编译
