supervisor 的更新
仅为随机记录，以便后续遗忘参考使用
当已运行的supervisor 更新时，因时间久远，遇到种种问题，仅做记录备案
目的：
-
为supervisor 添加一个新程序
-
重新启动supervisord后，Web界面可以控制管理新程序
1. 为新程序添加配置文件
[root@server-247 ~]# cd /etc/supervisor/conf.d/
[root@server-247 conf.d]# vi RiskcopInitDynServerV2_Basic.ini
2. 具体内容如下：
[root@server-247 conf.d]# cat RiskcopInitDynServerV2_Basic.ini
[program:RiskCop_Init_DynServerV2_Basic] # 为程序的名称
command=bash -c "lsof -i :7799 |awk 'NR==2{print$2}' |xargs kill -9; python3 Init_Heart_0923.py" #需要执行的命令
directory=/home/TestEnv/riskcop/FunctionalTest/Risk_Init_DynV2_Basic/Init0510/Init_Scripts/ #命令执行的目录
#environment=ASPNETCORE__ENVIRONMENT=Production #环境变量
user=root #用户
priority=999
stopsignal=INT
autostart=true #是否自启动
startsecs=10 # #指程序启动时需要程序至少稳定运行x秒才认为程序运行正常，在这x秒中程序状态为正在启动（s）
autorestart=true #是否自动重启
startretries=3 # # 重启失败拉起次数
#stderr_logfile=/var/log/RiskcopInit_Server.err.log #错误日志文件
#stdout_logfile=/var/log/RiskcopInit_Web.out.log #输出日志文件
redirect_stderr=true
stderr_logfile_maxbytes=20MB
stderr_logfile_backups = 20
stderr_logfile=/etc/supervisor/logs/RiskcopInitDynServerV2Basic.err.log #错误日志文件
stdout_logfile_maxbytes=20MB
stdout_logfile_backups = 20
stdout_logfile=/etc/supervisor/logs/RiskcopInitDynServerV2Basic.out.log #输出日志文件
stopasgroup=true
killasgroup=true
3. 查看
[root@server-247 conf.d]# ll
total 24
-rw-r--r--. 1 root root 1152 Mar 28 17:49 RiskcopInitDynServer.ini
-rw-r--r--. 1 root root 1149 Nov 25 2022 RiskcopInitDynServer.ini_bak
-rw-r--r-- 1 root root 1190 Jun 13 10:40 RiskcopInitDynServerV2_Basic.ini
-rw-r--r--. 1 root root 1146 Mar 28 18:11 RiskcopInitServer.ini
-rw-r--r--. 1 root root 1143 Feb 15 16:34 RiskcopInitServer.ini_bak
-rw-r--r--. 1 root root 1051 Mar 28 18:03 RiskcopInitWeb.ini
[root@server-247 conf.d]#
[root@server-247 conf.d]#
[root@server-247 conf.d]#
2. 修改配置文件后，重启动程序时，报错如下：
错误原因最后定位是 supervisor 配置文件编码格式非 utf-8 造成
[root@server-247 etc]# supervisord -c /etc/supervisord.conf
Error: 'utf-8' codec can't decode byte 0xb3 in position 48: invalid start byte
For help, use /usr/local/bin/supervisord -h
[root@server-247 etc]#
[root@server-247 etc]#
错误原因：配置文件编码格式问题，经检查 supervisor 的配置文件读取的是 /etc/supervisord.conf 中的 /etc/supervisor/conf.d/*.ini 如下：
[root@server-247 etc]#并且 supervisor 的配置文件路径可以查看
[root@server-247 etc]# cat /etc/supervisord.conf
; Sample supervisor config file.
...
...
...; interpreted as relative to this file. Included files *cannot*
; include files themselves.[include]
files = /etc/supervisor/conf.d/*.ini # 此处是supervisor 配置文件路径，

# 查询文件编码格式命令

[root@server-247 conf.d]# file -i RiskcopInitDynServer.ini
RiskcopInitDynServer.ini: text/plain; charset=utf-8
[root@server-247 conf.d]#
[root@server-247 conf.d]# file -i RiskcopInitDynServerV2_Basic.ini
RiskcopInitDynServerV2_Basic.ini: text/plain; charset=iso-8859-1 # 编码格式 iso-8859-1
[root@server-247 conf.d]# 2.2 修改 RiskcopInitDynServerV2_Basic.ini 编码格式为：utf-8
本人偷懒，使用Nodepad++ 更改 程序配置文件RiskcopInitDynServerV2_Basic.ini 的编码格式，具体方式如下图所示，更新后保存即可
3. 重启supervisor
先关闭supervisor启动脚本，之后再关闭supervisord服务
# 先关闭 运行的程序，方法2种：
方法一： 命令关闭所有程序
# supervisorctl stop all
方法二： Web 界面关闭所有程序
# 杀死 supervisord 进程
# ps aux | grep supervisord
# kill pid
[root@server-247 conf.d]# ps -ef|grep supervisor
root 14545 1 0 Jul24 ? 00:01:06 /usr/bin/python3 /usr/local/bin/supervisord -c /etc/supervisord.conf
root 166160 149571 0 10:53 pts/14 00:00:00 grep --color=auto supervisor
[root@server-247 conf.d]#
[root@server-247 conf.d]#
[root@server-247 conf.d]# kill -9 14545
[root@server-247 conf.d]#
[root@server-247 conf.d]# ps -ef|grep supervisor
root 167421 149571 0 11:03 pts/14 00:00:00 grep --color=auto supervisor
[root@server-247 conf.d]#
方法二： Web 界面关闭所有程序
3.1
# 启动supervisor (启动服务端)
[root@server-247 etc]# supervisord -c /etc/supervisord.conf
Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.
For help, use /usr/local/bin/supervisord -h
[root@server-247 etc]#
# 提示已在运行
结束supervisor,后重新运行即可
[root@server-247 etc]# ps -ef|grep supervisor
root 31179 1 0 May16 ? 00:10:54 /usr/bin/python3 /usr/local/bin/supervisord -c /etc/supervisord.conf

root 69425 67518 0 11:11 pts/194 00:00:00 grep --color=auto supervisor
[root@server-247 etc]#
启动错误问题2：
当运行 supervisord -c /etc/supervisord.conf 命令时，出现了 "Unlinking stale socket /tmp/supervisor.sock" 的错误提示。这个错误通常发生在之前的Supervisor进程意外终止或没有正确关闭的情况下
# 查询 supervisor 未启动
[root@server-248 supervisor]# ps -ef|grep supervisor
root 132781 126069 0 10:49 pts/19 00:00:00 tail -f /tmp/supervisord.log
root 134333 266539 0 10:52 pts/9 00:00:00 grep --color=auto supervisor
[root@server-248 supervisor]#
[root@server-248 supervisor]## 启动 supervisor
[root@server-248 supervisor]# supervisord -c /etc/supervisord.conf
Unlinking stale socket /tmp/supervisor.sock # 上次未[root@server-248 supervisor]#
[root@server-248 supervisor]# rm /tmp/supervisor.sock
rm: remove socket ‘/tmp/supervisor.sock’? y
[root@server-248 supervisor]#
3.2 启动supervisor 服务端
[root@server-247 etc]# supervisord -c /etc/supervisord.conf
[root@server-247 etc]#
[root@server-247 etc]# ps -ef|grep supervisor
