supervisor安装

1. 安装

   # centos自带的源无supervisor,因此安装扩展源
   yum install -y epel-release
   yum install supervisor -y
   

2. 管理

   # 启动
   systemctl status supervisord.service
   # 重启
   systemctl restart supervisord.service
   # 停止
   systemctl stop supervisord.service
   # 状态
   systemctl status supervisord.service
   # 开机启动
   systemctl enable supervisord.service
   # 取消开机启动
   systemctl disable supervisord.service
   

3. 命令

   supervisorctl --help
   

4. 默认配置修改

   # 编辑配置
   vim /etc/supervisord.conf
   # 启动web服务（去掉注释，修改用户名及密码）
   [inet_http_server]         ; inet (TCP) server disabled by default
   port=0.0.0.0:9001        ; (ip_address:port specifier, *:port for all iface)
   username=user              ; (default is no username (open server))
   password=123               ; (default is no password (open server))
   # 保存退出后，重启
   systemctl restart supervisord.service
   # 修改防火墙允许9001端口访问 (如果使用防火墙)
   firewall-cmd --permanent --zone=public --add-port=9001/tcp
   firewall-cmd --reload
   

5. 增加一个测试程序

   vim /etc/supervisord.d/test.ini
   # 写入
   [program:test]
   command=/usr/local/redis-4.0.8/src/redis-server /usr/local/redis-4.0.8/redis.conf
   # 保存退出后重启
   systemctl restart supervisord.service
