nginx 健康檢查配置

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模式的錯誤信息，用於查看詳細的報錯信息，默認是沒debug功能的
error_log /Users/opt/nginx/logs/error.log debug;
}
}

debug模式開始方式
在 nginx 解壓包中運行該命令
./configure --prefix=/usr/local/nginx --with-debug

make & make install
說明：

• –prefix=/usr/local/nginx 設置新編譯的輸出目錄
• –with-debug 開啓debug功能

當需要配置https的時候也是這個流程，默認是沒有SSL 那個模塊的，也得 --with-XXX（具體模塊名忘了）這樣重新編譯
