一、安裝配置supervisor

1.安裝python自動化工具    #yum install python-setuptools

2.#easy_install supervisor安裝supervisor

3.測試安裝是否成功 #echo_supervisord_conf

4.建立設定檔：

（1）建立supervisor設定檔目錄/etc/supervisor/  

#mkdir -m 755 -p /etc/supervisor/

（2）建立主配檔案supervisord.conf

#echo_supervisord_conf > /etc/supervisor/supervisord.conf

（3）建立項目設定檔目錄

# mkdir -m 755 conf.d

5.在設定檔目錄中添加測試組態檔案 
如：convert.ini

然後在主設定檔supervisord.conf的最下面添加

[include]

file = ./conf.d/convert.ini

6.啟動supervisor---手動啟動

# supervisord -c /etc/supervisor/supervisord.conf

pstree -p | grep supervisord

查看supervisord.log發現program convert已啟動

# cat /tmp/supervisord.log

7.#supervisorctl -c /etc/supervisor/supervisord.conf  進入到supervisor管理

status 查看狀態

stop all停止

reload重啟監控服務

注意：

（1）每次修改設定檔後需進入supervisorctl，執行reload， 改動部分才會生效

（2）兩個命令

supervisord : supervisor的伺服器端部分，用於supervisor啟動

supervisorctl：啟動supervisor的命令列視窗，在該命令列中可執行start、stop、status、reload等操作。

 

二、supervisord啟動指令碼

1.執行如下命令：

vim /etc/init.d/supervisord

2.輸入如下內容：

#!/bin/bash## supervisord   This scripts turns supervisord on# chkconfig:345 83 04# description:  supervisor is a process control utility.

We‘ve waited roughly 60 seconds, we‘ll let it do its thing from here"            return 1          else            sleep $sleep            total_sleep=$(( $total_sleep + $sleep ))          fi        fi      done    fi    # always remove the subsys. We might have waited a while, but just remove it at this point.    rm -f $LOCKFILE}restart() {    stop    start}case "$1" in  start)    start    RETVAL=$?    ;;  stop)    stop    RETVAL=$?    ;;  restart|force-reload)    restart    RETVAL=$?    ;;  reload)    $SUPERVISORCTL $OPTIONS reload    RETVAL=$?    ;;  condrestart)    [ -f $LOCKFILE ] && restart    RETVAL=$?    ;;  status)    $SUPERVISORCTL $OPTIONS status    if running ; then      RETVAL=0    else      RETVAL=1    fi    ;;  *)    echo $"Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart}"    exit 1esacexit $RETVAL

注意：該檔案中的如下幾個變數，都需要根據你實際的目錄來改寫。

PREFIX=/usrSUPERVISORD=$PREFIX/bin/supervisord      ##supervisord   程式的安裝路徑SUPERVISORCTL=$PREFIX/bin/supervisorctl  ##supervisorctl 程式的安裝路徑PIDFILE=/var/supervisor/supervisord.pid   ##需要先建立/var/supervisor目錄LOCKFILE=/var/supervisor/supervisord.lockOPTIONS="-c /etc/supervisor/supervisord.conf"   ##設定檔的路徑

 儲存完畢之後，可以執行以下命令修改檔案許可權：

chmod 777 /etc/init.d/supervisord/etc/init.d/supervisord  start或service supervisord start

 這樣supervisor就啟動了

3. 配置開機啟動

執行以下命令：

chkconfig supervisord  on

可以以下命令查看是否成功

chkconfig --list | grep  supervisord
