在 CentOS7.x 系统中一键安装 supervisord 服务，适用系统自带的python2.7版本，升级与否都可。

软件 版本
OS CentOS 7.x
supervisor 4.2.1
setuptools 41.0.0
meld 3-2.0.1

安装步骤

默认安装在/home/supervisor下，也可指定安装目录参数自定义安装。执行完安装脚本，就可以在 /home/supervisor 目录下看到有相应的配置文件目录etc、日志目录logs及临时文件目录tmp，并且使用 systemd 对 supervisord 进行管理，安装完成后会自动销毁安装文件。

1.使用 root 用户上传 supervisor_install.tar.gz 到任意目录

cd /root
wget -c https://github.com/ghl1024/supervisor-install/releases/download/V1.0/supervisor_install.tar.gz

2.解压

tar xf supervisor_install.tar.gz

3.进入到目录

cd supervisor_install

4.执行安装脚本

./supervisor_install.sh                     #不跟参数默认安装在/home/supervisor下
./supervisor_install.sh /opt/supervisor     #安装在/opt/supervisor下
./supervisor_install.sh /data/supervisor    #安装在/data/supervisor下

5.查看状态

systemctl status supervisord.service
netstat -tnlp | grep "9001" | grep -v "grep"
ps -ef | grep "supervisord" | grep -v "grep"

supervisor和 systemd 对比

supervisor

优点

  • 可以通过网页执行启动停止的操作
  • 单配置文件可控制多个程序
  • 可控制进程数量
  • 进程资源控制能力比较强

缺点

  • 本身需要被监控
  • 开机自启依赖其他程序
  • 不能跨主机
  • 依赖于meld3、setuptools
  • 进程需在前台运行

systemd

优点

  • 可使用模板文件
  • 附带定时器、路径监控器、数据监控器等功能
  • 比较弱的跨主机能力，节点必须互相添加ssh key信任，只能远程控制已有的服务
  • 开机可以自启
  • 大多数发行版的标准配置
  • 配套journalctl二进制保存日志很难伪造，日志格式统一，日志大小可限制
  • 限制特定服务可用的系统资源量例如CPU、程序堆栈、文件句柄数量、子进程数量

缺点

  • 多配置文件才能配置多个程序

supervisor 常用命令

supervisorctl update 
#更新新的配置到supervisord（不会重启原来已运行的程序）

supervisorctl reload 
#载入所有配置文件，并按新的配置启动、管理所有进程（会重启原来已运行的程序）

supervisorctl start xxx 
#启动某个进程

supervisorctl restart xxx 
#重启某个进程

supervisorctl stop xxx 
#停止某一个进程(xxx)，xxx为[program:theprogramname]里配置的值

supervisorctl stop groupworker 
#重启所有属于名为groupworker这个分组的进程(start,restart同理)

supervisorctl stop all 
#停止全部进程，注：start、restart、stop都不会载入最新的配置文

supervisorctl reread 
#当一个服务由自动启动修改为手动启动时执行一下就ok
