jenkins结合supervisor进行python程序发布后的自动重启

jenkins结合supervisor进行python程序发布后的自动重启

项目背景：
通过jenkins发布kvaccount.chinasoft.com站点的python服务端程序，业务部门同事需要每次发布完成须后自动重启python服务端


具体执行中遇到的问题：
代码的目录是apache的属主权限，通过jenkins远程调用脚本，强制关闭服务进程，再次启动进程，发现程序能正常重启，但是会夯住，导致jenkins发布job没法结束，想到supervisor都能没有tty的情况下管理程序，于是安装supervisor进行进程的管理

脚本如下:
直接在终端下可以正常重启程序，在jenkins程序调用的时候就失效了，导致程序夯住

#---------------------------------------------
[root@:/data/www/vhosts/kvaccount.chinasoft.com/httpdocs/Source]# cat restart_kvaccount.sh
#!/bin/bash
#
# kill fastcgi.py
source /etc/profile
py_num=`ps -ef|grep fastcgi.py|grep -v grep|wc -l`
if [ $py_num -ge 1 ];then
ps -ef|grep fastcgi.py|grep -v grep|awk '{print $2}'|xargs kill -9

# start it
#su apache -c "cd /data/www/vhosts/kvaccount.chinasoft.com/httpdocs/Source && nohup python3 fastcgi.py > /dev/null &"
cd /data/www/vhosts/kvaccount.chinasoft.com/httpdocs/Source && nohup python3 fastcgi.py > /dev/null &

exit 0
#---------------------------------------------

1.安装supervisor
pip3 install supervisor

cp /usr/local/python373/bin/supervisorctl /usr/bin/
cp /usr/local/python373/bin/supervisord /usr/bin/

2.添加配置

mkdir -p /etc/supervisor/conf.d

# 主配置supervisord.conf 

[root@srv3:/etc/supervisor/conf.d]# cat /etc/supervisor/supervisord.conf 
; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Quotes around values are not supported, except in the case of
;    the environment= options as shown below.
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
;  - Command will be truncated if it looks like a config file comment, e.g.
;    "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".

# 程序的守护程序配置
[root@srv3:/etc/supervisor/conf.d]# cat service-worker.conf 
[program:chinasoft-account]
process_name=%(program_name)s_%(process_num)02d
command=/usr/local/bin/python3 /data/www/vhosts/kvaccount.chinasoft.com/httpdocs/Source/fastcgi.py
autostart=true
autorestart=true
user=apache
numprocs=1
numprocs_start=1
redirect_stderr=true

3.启动supervisor程序
chown -R apache.users /etc/supervisor
# 启动supervisor
/usr/local/bin/python3 /usr/bin/supervisord -c /etc/supervisor/supervisord.conf -u apache

4.发布程序apache账号的ssh方式进行重启python程序脚本


# 发布代码后自动重启python的shell脚本
[root@srv3:/etc/supervisor/conf.d]# cat /data/www/vhosts/kvaccount.chinasoft.com/httpdocs/Source/restart_kvaccount.sh 
#!/bin/bash
#
# kill fastcgi.py
#!/bin/sh 
source /etc/profile

/usr/bin/supervisorctl restart chinasoft-account:*


# python服务端相关程序和配置
