supervisor进程管理工具

supervisor学习

• 首先安装Supervisor，系统自带pip,因为截至目前Supervisor还不支持Python3,不过并不影响使用。

  pip install supervisor
  

• 为了方便，创建目录结构，来管理Supervisor有关的文件：

  /root/etc
  ├── supervisor
  │   ├── conf.d
  │   └── var
  │       ├── log
  └── supervisord.conf
  
  

• 首先建立上述的目录结构

  mkdir -p ~/etc/supervisor/conf.d
  mkdir -p ~/etc/supervisor/var/log
  

• 然后进入~/etc目录下生成Supervisor的配置文件

  cd ~/etc
  echo_supervisord_conf > supervisord.conf
  

• 进入supervisord.conf:

  vim supervisord.conf
  

• 首先找到[unix_http_server]，更改配置，指定supervisor.sock文件位置。

  [unix_http_server]
  file=/root/etc/supervisor/var/supervisor.sock
  

• 更改[supervisord]配置：

  [supervisord]
  logfile=/root/etc/supervisor/var/log/supervisord.log
  pidfile=/root/etc/supervisor/var/supervisord.pid
  user=root
  

• 更改[supervisorctl]配置：

  [supervisorctl]
  serverurl=unix:///root/etc/supervisor/var/supervisor.sock
  

• 更改[include]配置：

  [include]
  files = /root/etc/supervisor/conf.d/*.ini
  

• 在conf.d新建一个文件newprocess.ini配置uwsgi

  [program:uwsgi]
  command=/opt/west_env/bin/uwsgi --ini /opt/west_coast__company_project/west_coast__company_project/uwsgi.ini
  directory=/opt/west_coast__company_project/west_coast__company_project/
  # 开始等待时间
  startsecs=0
  # 停止等待时间
  stopwaitsecs=0
  autostart=true
  # 进程意外退出时重启
  autorestart=true
  # 进程运行的用户，防止权限问题
  user=root
  stdout_logfile=/root/etc/supervisor/var/log/newprocess-stdout.log
  stderr_logfile=/root/etc/supervisor/var/log/newprocess-stderr.log
  [program:nginx]
  command=/usr/sbin/nginx
  directory=/usr
  startsecs=0
  stopwaitsecs=0
  autostart=true
  autorestart=true
  user=root
  stdout_logfile=/root/etc/supervisor/var/log/nginx-stdout.log
  stderr_logfile=/root/etc/supervisor/var/log/nginx-stderr.log
  [program:redis]
  command=systemctl start redis
  directory=/etc
  startsecs=0
  stopwaitsecs=0
  autostart=true
  autorestart=true
  user=root
  stdout_logfile=/root/etc/supervisor/var/log/redis-stdout.log
  stderr_logfile=/root/etc/supervisor/var/log/redis-stderr.log
  [program:mysql]
  command=systemctl start mariadb
  directory=/etc
  startsecs=0
  stopwaitsecs=0
  autostart=true
  autorestart=true
  user=root
  stdout_logfile=/root/etc/supervisor/var/log/mysql-stdout.log
  stderr_logfile=/root/etc/supervisor/var/log/mysql-stderr.log
  

• 启动管理进程命令

  /usr/bin/supervisord -c ~/etc/supervisord.conf
  

• 查看是否启动成功

  ps -ef | grep supervisor
  

• 进入 supervisorctl 进程管理控制台 ：

/usr/bin/supervisorctl -c ~/etc/supervisord.conf

• 启动

  reload
  start all
  stop all
  restart uwsgi(uwsgi指定program配置名字)
  

2简化版配置

# 生成自定义文件
vim supervisorconf.conf
# 配置信息如下：
# 此处只配置uwsgi即可，nginx是守护进程所以可以不用supervisor管理
[program:uwsgi_process]
command = /opt/west_env/bin/uwsgi --ini /opt/west_coast__company_project/west_coast__company_project/uwsgi.ini
directory = /opt/west_coast__company_project
startsecs = 0
stopwaitsecs = 0
autostart = true
autorestart = true
stdout_logfile=/root/etc/supervisor/var/log/newprocess-stdout.log
stderr_logfile=/root/etc/supervisor/var/log/newprocess-stderr.log


[supervisord]
loglevel = info

[inet_http_server]
port = :9001
username = root
password = 123


[supervisorctl]
serverurl = http://127.0.0.1:9001
username = root
password = 123

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterfac

• 注意：执行supervisorctl 交互式操作时，stop 无法关闭uwsgi原因是，uwsgi内配置文件 注释掉 daemonize ，然后别忘了reload

# 指定文件启动服务
/usr/bin/supervisord  -c ~/etc/supervisorconf.conf 
# 此时开启交互模式，然后启动交互式
/usr/bin/supervisorctl -c ~/etc/supervisorconf.conf 
supervisor > start 命program名
