linux 进程管理 supervisor

supervisor 安装（本文在ubuntu下安装）

配置阿里云源

root@bogon:/etc/apt# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 15.10
Release:        15.10
Codename:       wily

显示了一些ubuntu的版本信息，需要得到的是Codename，比如，我这里是wily
查看：http://mirrors.aliyun.com/help/ubuntu

  deb http://mirrors.aliyun.com/ubuntu/ quantal main restricted universe multiverse
  deb http://mirrors.aliyun.com/ubuntu/ quantal-security main restricted universe multiverse
  deb http://mirrors.aliyun.com/ubuntu/ quantal-updates main restricted universe multiverse
  deb http://mirrors.aliyun.com/ubuntu/ quantal-proposed main restricted universe multiverse
  deb http://mirrors.aliyun.com/ubuntu/ quantal-backports main restricted universe multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ quantal main restricted universe multiverse

上面quantal 替换为Codename中：wily

root@bogon:/etc/apt# mv sources.list sources.list_bak
root@bogon:/etc/apt# vi sources.list #添加下面内容
deb http://mirrors.aliyun.com/ubuntu/ wily main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ wily-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ wily main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ wily-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ wily-backports main restricted universe multiverse

阿里云源配置完毕

install supervisor

1. apt-get install supervisor
2. 配置supervisor.conf

vi supervisor.conf 
[include]
files = /etc/supervisor/conf.d/*.conf  #此*.conf是需要被管理进程配置文件

3. 配置被管理进程
   cd /etc/supervisor/conf.d/
   vi test.conf

[program:test]            #进行名称
dirctory=/home/aapon/abs_tomcat/bin   #目录
environment=JAVA_HOME="/home/aapon/tomcat/jdk1.7.0_75",JAVA_BIN="/home/aapon/tomcat/jdk1.7.0_75/bin"  #java环境变量
command=/home/aapon/abs_tomcat/bin/startup.sh run   #启动命令
autostart=true   #在supervisord启动的时候也自动启动
startsecs=5       #启动10秒后没有异常退出，就表示进程正常启动了，默认为1秒
autorestart=true   #程序退出后自动重启
startretries=3   #启动失败自动重试次数，默认是3
user=test      #用什么用户启动

supervisor 启动命令

1. 启动supervisor服务 进程 sudo supervisord -c /etc/supervisor/supervisor.conf

2. 启动进程

supervisor 管理tomcat进程过程遇到的坑

1. 使用 supervisord 监控管理的进程必须以 nodaemon 启动，而 tomcat 的 startup.sh 脚本是daemon方式的，如果不做修改的话，supervisord 会一直报错
   在 startup.sh 的最后的
   exec "$PRGDIR"/"$EXECUTABLE" start "$@" 改为
   exec "$PRGDIR"/"$EXECUTABLE" run "$@"
