yum -y install epel-release
yum -y install python-pip2. supervisor因为supervisor是python写的所以直接通过pip进行安装即可。
[rootk8s-node1 ~]# pip install supervisor

You should consider upgrading via the pip install --upgrade pip command.

Successfully installed pip-18.13. supervisord这个就是supervisor的server端启动之前生成一个默认的配置文件放在 /data/supervisor/目录下。
[rootk8s-node1 supervisor]# pwd
/data/supervisor
[rootk8s-node1 supervisor]# echo_supervisord_conf ./supervisord.conf
[rootk8s-node1 supervisor]# ls
supervisord.conf关于配置文件的详细配置你可以参考官方的http://www.supervisord.org/configuration.html
[unix_http_server]
file/tmp/supervisor.sock[supervisord]
logfile/tmp/supervisord.log ; main log file; default $CWD/supervisord.log
logfile_maxbytes50MB ; max main logfile bytes b4 rotation; default 50MB
logfile_backups10 ; # of main logfile backups; 0 means none, default 10
loglevelinfo ; log level; default info; others: debug,warn,trace
pidfile/tmp/supervisord.pid ; supervisord pidfile; default supervisord.pid
nodaemonfalse ; start in foreground if true; default false
minfds1024 ; min. avail startup file descriptors; default 1024
minprocs200 ; min. avail process descriptors;default 200; The rpcinterface:supervisor p must remain in the config file for
; RPC (supervisorctl/web interface) to work. Additional interfaces may be
; added by defining them in separate [rpcinterface:x] ps.[rpcinterface:supervisor]
supervisor.rpcinterface_factory supervisor.rpcinterface:make_main_rpcinterface; The supervisorctl p configures how supervisorctl will connect to
; supervisord. configure it match the settings in either the unix_http_server
; or inet_http_server p.[supervisorctl]
serverurlunix:///tmp/supervisor.sock ; use a unix:// URL for a unix socket上面的文件主要改两个地方开启supervisor的可视化界面
;[inet_http_server] ; inet (TCP) server disabled by default
;port127.0.0.1:9001 ; ip_address:port specifier, *:port for all iface
;usernameuser ; default is no username (open server)
;password123 ; default is no password (open server)改成
[inet_http_server] ; inet (TCP) server disabled by default
port0.0.0.0:9001 ; ip_address:port specifier, *:port for all iface
;usernameuser ; default is no username (open server)
;password123 ; default is no password (open server)下面这个语法表示可以加载指定目录的所有ini文件这个口子就方便我们给每个应用程序配一个xx.ini文件这样当你update的时候supervisor会自动 将conf目录下*.ini文件和supervisor.conf进行合并。
;[include]
;files relative/directory/*.ini改成
[include]
files ./conf/*.ini最后启动一下更多的你可以通过help命令查看。[rootk8s-node1 supervisor]# supervisord -c ./supervisord.conf
4. supervisorctlsupervisotctl 是一个客户端工具通过9001端口与server进行交互可处理如下18个命令。
[rootk8s-master supervisord]# supervisorctl helpdefault commands (type help topic):add exit open reload restart start tail
avail fg pid remove shutdown status update
clear maintail quit reread signal stop version接下来可以在conf目录下生成一个 consoleapp3.ini 文件程序名为:consoleapp3。
[rootk8s-master conf]# tail consoleapp3.ini
[program:consoleapp3]
command/usr/bin/dotnet /data/supervisord/ConsoleApp3/ConsoleApp3.dll
autostarttrue
autorestarttrue
stdout_logfile/data/supervisord/ConsoleApp3/1.log执行以下update命令让supervisor重新加载配置文件。[rootk8s-master supervisord]# supervisorctl update
回到文章开头的问题如果生成多个副本你可以采用group模式比如下面这样的 mytest.ini 文件放置到conf目录下。
[group:mytest]
programsmytest1,mytest2,mytest3[program:mytest1]
command/usr/bin/dotnet /data/supervisord/mytest/ConsoleApp1.dll
autostarttrue
autorestarttrue
stdout_logfile/data/supervisord/mytest/4.log[program:mytest2]
command/usr/bin/dotnet /data/supervisord/mytest/ConsoleApp1.dll
autostarttrue
autorestarttrue
stdout_logfile/data/supervisord/mytest/5.log[program:mytest3]
command/usr/bin/dotnet /data/supervisord/mytest/ConsoleApp1.dll
autostarttrue
autorestarttrue
stdout_logfile/data/supervisord/mytest/6.log然后通过 supervisorctl update 让supervisor重新加载配置文件然后可观察可视化界面。
[rootk8s-master conf]# supervisorctl update
mytest: added process group有了这个基础之后和jenkins集成就很简单了因为9001端口被占用就重新指定了一个19001端口把应用程序的*.ini文件放在解决方案里这样自动化的时候就可以找到*.ini文件然后copy到supervisor的conf目录下因为是强制copy所以用管道模式 yes | .....1)普通模式
supervisorctl -s http://localhost:19001 stop memsql-test \cd ./MemSql.NetCore/MemSql.Test \yes | cp ./doc/memsql-test.ini /data/supervisor/conf/ \dotnet publish -o /data/output/MemSql.Test -c Release \supervisorctl -s http://localhost:19001 update \supervisorctl -s http://localhost:19001 start memsql-test2)组模式
supervisorctl -s http://localhost:19001 stop memsql-automationdeploy:* \cd ./MemSql.NetCore/MemSql.AutomationDeploy \yes | cp ./doc/memsql-automationdeploy.ini /data/supervisor/conf/ \dotnet publish -o /data/output/MemSql.AutomationDeploy -c Release \supervisorctl -s http://localhost:19001 update \supervisorctl -s http://localhost:19001 start memsql-automationdeploy:*好了本篇就说到这里如果有人问多机器怎么玩下篇再说ansible~
