安装supervisor

安装supervisor

在centOS6.8 下安装supervisor,

       

配置好yum源后，可以直接安装

yum install supervisor
Debian/Ubuntu可通过apt安装

apt-get install supervisor
pip安装

pip install supervisor
easy_install安装

easy_install supervisor

 

1. 下载setuptools

wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | sudo python

然后输入sudo密码

到安装完成即可

 

1. 安装supervisor

进入root

执行 easy_install supervisor

安装完成即可

 

1. 离线安装

tar -xvf  meld3-1.0.2.tar.gz 

进入解压目录 python setup.py install

tar -xvf  supervisor-3.3.1.tar.gz 

进入解压目录 python setup.py install

即可。

 

 

在 Ubuntu下直接 apt-get

sudo apt-get  install  supervisor

 

安装即可

 

3．生成supervisor.conf

mkdir -p /etc/supervisor/conf.d

 

初始化supervisord.conf

echo_supervisord_conf > /etc/supervisor/supervisord.conf

 

修改supervisord.conf

vim /etc/supervisor/supervisord.conf

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

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

 

配置include路径

[include]

files = /etc/supervisor/conf.d/*.conf

 

 

 

 

注意事项

注意Supervisor只能管理非daemon的进程，所以tomcat 要以catalina.sh  run前台方式执行。

 

 

添加进程管理

创建进程管理文件，并放入conf.d

如下

 

 

 

 

进程管理文件如下：

 

[program:onehee-tomcat]

command=/opt/soft/apache-tomcat/bin/catalina.sh run

directory=/opt/soft/apache-tomcat/bin/

autorestart=true

user=root

autostart=true

stdout_logfile=/opt/soft/apache-tomcat/logs/catalina.out

redirect_stderr=true

stdout_logfile_maxbytes=100MB

stdout_logfile_backups=10

 

 

 

 

 

 

开机启动supervisor

把supervisord 文件(见附录文档)放在 /etc/init.d/

 

在supervisord中需要修改一下JAVA 路径（默认/usr/java/ jdk1.7.0_79/bin）即可

 

#!/bin/bash
# chkconfig: - 85 15

#PATH=/sbin:/bin:/usr/sbin:/usr/bin
export PATH="$PATH:/usr/java/jdk1.8.0_131/bin"

PROGNAME=supervisord

DAEMON=/usr/bin/$PROGNAME

CONFIG=/etc/supervisor/$PROGNAME.conf

PIDFILE=/tmp/$PROGNAME.pid

DESC="supervisord daemon"

SCRIPTNAME=/etc/init.d/$PROGNAME

# Gracefully exit if the package has been removed.

test -x $DAEMON || exit 0


start(){

echo -n "Starting $DESC: $PROGNAME"

$DAEMON -c $CONFIG

echo ".............start success"

}

stop(){

echo "Stopping $DESC: $PROGNAME"

if [ -f "$PIDFILE" ];
then
supervisor_pid=$(cat $PIDFILE)
kill -15 $supervisor_pid
echo "......"
echo "stop success"
else
echo "$DESC: $PROGNAME is not Runing"
echo ".........................stop sucess"
fi
}

status(){ 
statusport=`netstat -lntp|grep 9001|awk -F ‘ ‘ ‘{print $4}‘|awk -F ‘:‘ ‘{print $2}‘`

if [ -f "$PIDFILE" ];
then 
supervisor_pid=$(cat $PIDFILE)
echo "$DESC: $PROGNAME is Runing pid=$supervisor_pid"
else
echo "$DESC: $PROGNAME is not Runing"
echo "please use command /etc/init.d/supervisord start Run the service"
fi
}

case "$1" in

start) start;;

stop) stop ;;

restart) stop

start ;;

status) status ;;

*) echo "Usage: $SCRIPTNAME {start|stop|restart}" >&2

exit 1 ;;

esac

exit 0

 

chmod 755 supervisord

chkconfig --add  supervisord 

chkconfig supervisord on

 

chkconfig --list | grep supervisord

 

 

 

 

然后可以通过

service supervisord start/stop/restart

来管理supervisor本身,开机自启

 

 

问题

1. supervisor 管理storm环境，无法找到storm 命令

则在/usr/bin 建立storm命令的软连接，或者在 command中输入storm全路径

 

 

1. supervisord 文件中，PATH中加入/usr/java/ jdk1.7.0_79/bin,否则出现 OSError: [Errno 2] No such file or directory 错误
