Supervisor

supervisor 安装方案

pip 安装方案

1、适配不支持yum 安装的服务器,使用pip3 进行安装

$ pip3 install supervisor

2、创建对应的配置文件

$ echo_supervisord_conf | sudo tee /etc/supervisord.conf  

3、使用systemd 管理supervisor

 cat > /etc/systemd/system/supervisord.service <<EOF
[Unit]
Description=Supervisor process control system
After=network.target  
[Service]
Type=forking          
ExecStart=/usr/local/bin/supervisord -c /etc/supervisord.conf  
ExecStop=/usr/local/bin/supervisord/supervisorctl shutdown  
ExecReload=/usr/local/bin/supervisorctl reload  
User=root             
Restart=on-failure    
RestartSec=10s         
[Install]
WantedBy=multi-user.target
EOF

4、 重载systemd 配置,并配置开机自启

$ systemctl daemon-reload
$ systemctl enable --now supervisord

5、 优化supervisor 子配置管理

$ mkdir -p /etc/supervisord.d/
$ sed -i "s#;\[include\]#\[include\]#g"  /etc/supervisord.conf
$ sed -i "s#;files = relative/directory/\*\.ini#files = /etc/supervisord\.d/\*\.ini#g" /etc/supervisord.conf 

6、 重启服务

$ systemctl restart supervisord

7、如何使用supervisior启动一个java 服务

$ cat > /etc/supervisord.d/test.ini <<EOF
[program:test]
directory=/opt/test # 服务工作目录
#command=/usr/bin/java -Xms5g -Xmx5g -Duser.timezone=America/Mexico_City -jar push-center-1.0.0-SNAPSHOT.jar
command=/usr/bin/java -jar test.jar -Duser.timezone=GMT+07 --spring.profiles.active=prod -Xmx512m -Xms512m # 服务启动命令
user=root # 什么用户启动服务
redirect_stderr=true # 重定向错误输出
stdout_logfile_backups=7 # 日志转存时间
stdout_logfile=/opt/clc-push/clc-push.log # 日志输出位置
EOF

完整例子如下：
$ cat > /etc/supervisord.d/test.ini <<EOF
[program:test]
directory=/opt/test 
command=/usr/bin/java -jar test.jar -Duser.timezone=GMT+07 --spring.profiles.active=prod -Xmx512m -Xms512m 
user=root 
redirect_stderr=true
stdout_logfile_backups=7
stdout_logfile=/opt/clc-push/clc-push.log
EOF

8、完整安装脚本如下

#!/bin/bash
pip3 install supervisor
echo_supervisord_conf | sudo tee /etc/supervisord.conf  

cat > /etc/systemd/system/supervisord.service <<EOF
[Unit]
Description=Supervisor process control system
After=network.target  
[Service]
Type=forking          
ExecStart=/usr/local/bin/supervisord -c /etc/supervisord.conf  
ExecStop=/usr/local/bin/supervisord/supervisorctl shutdown  
ExecReload=/usr/local/bin/supervisorctl reload  
User=root             
Restart=on-failure    
RestartSec=10s         
[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload

systemctl enable --now supervisord

mkdir -p /etc/supervisord.d/
sed -i "s#;\[include\]#\[include\]#g"  /etc/supervisord.conf

sed -i "s#;files = relative/directory/\*\.ini#files = /etc/supervisord\.d/\*\.ini#g" /etc/supervisord.conf 

systemctl restart supervisord
