原文:netcore使用 jenkins + supervisor 实现standalone下多副本自动化发布

      上一篇我们用jenkins做了一个简单的自动化发布,在shell中采用的是 BUILD_ID=dontKillMe nohup dotnet xxx.dll &  这种简单的后台承载,如果你的业务

量相对比较小,可以用这个方法玩一玩,但存在二个问题:1. 无法对进程进行批量或者可视化管理。 2. 单机模式下的多副本部署比较麻烦,比如你在一台机

器上开启多个同样的程序来提高队列的处理能力,解决这两个问题你可以使用netcore官方推荐的supervisor 进程管理工具。

一: supervisor

       具体这玩意是干嘛的,我就不说了,大家自己看官网: http://www.supervisord.org/  接下来快速部署一下。

1.  pip 

    pip是python的一个包管理器,类似于nuget,如果你的centos上没有安装,那么请执行下面命令。

1 yum -y install epel-release2 yum -y install python-pip

2. supervisor

    因为supervisor是python写的,所以直接通过pip进行安装即可。

 1 [root@k8s-node1 ~]# pip install supervisor 2 Collecting supervisor 3 ??Downloading https://files.pythonhosted.org/packages/ba/65/92575a8757ed576beaee59251f64a3287bde82bdc03964b89df9e1d29e1b/supervisor-3.3.5.tar.gz (421kB) 4 ????100% |████████████████████████████████| 430kB 47kB/s ?5 Collecting meld3>=0.6.5 (from supervisor) 6 ??Downloading https://files.pythonhosted.org/packages/b6/ae/e6d731e4b9661642c1b20591d8054855bb5b8281cbfa18f561c2edd783f7/meld3-1.0.2-py2.py3-none-any.whl 7 Installing collected packages: meld3, supervisor 8 ??Running setup.py install for supervisor ... done 9 Successfully installed meld3-1.0.2 supervisor-3.3.510 You are using pip version 10.0.1, however version 18.1 is available.11 You should consider upgrading via the ‘pip install --upgrade pip‘ command.12 [root@k8s-node1 ~]# pip install --upgrade pip13 Collecting pip14 ??Downloading https://files.pythonhosted.org/packages/c2/d7/90f34cb0d83a6c5631cf71dfe64cc1054598c843a92b400e55675cc2ac37/pip-18.1-py2.py3-none-any.whl (1.3MB)15 ????100% |████████████████████████████████| 1.3MB 49kB/s 16 Installing collected packages: pip17 ??Found existing installation: pip 10.0.118 ????Uninstalling pip-10.0.1:19 ??????Successfully uninstalled pip-10.0.120 Successfully installed pip-18.1

3. 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。

1 [root@k8s-node1 supervisor]# pwd2 /data/supervisor3 [root@k8s-node1 supervisor]# echo_supervisord_conf > ./supervisord.conf4 [root@k8s-node1 supervisor]# ls5 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 ,

上面的文件主要改两个地方:

《1》 开启supervisor的可视化界面

;[inet_http_server] ????????; inet (TCP) server disabled by default;port=127.0.0.1:9001 ???????; ip_address:port specifier, *:port for all iface;username=user ?????????????; default is no username (open server);password=123 ??????????????; default is no password (open server)

 改成:

[inet_http_server] ????????; inet (TCP) server disabled by defaultport=0.0.0.0:9001 ?????????; ip_address:port specifier, *:port for all iface;username=user ?????????????; default is no username (open server);password=123 ??????????????; default is no password (open server)

《2》 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。

[root@k8s-node1 supervisor]# supervisord -c ./supervisord.conf

4. supervisorctl 

     supervisotctl 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。

[root@k8s-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。

[root@k8s-master conf]# tail consoleapp3.ini[program:consoleapp3]command=/usr/bin/dotnet /data/supervisord/ConsoleApp3/ConsoleApp3.dllautostart=trueautorestart=truestdout_logfile=/data/supervisord/ConsoleApp3/1.log

   

    执行以下update命令让supervisor重新加载配置文件。

[root@k8s-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]programs=mytest1,mytest2,mytest3[program:mytest1]command=/usr/bin/dotnet /data/supervisord/mytest/ConsoleApp1.dllautostart=trueautorestart=truestdout_logfile=/data/supervisord/mytest/4.log[program:mytest2]command=/usr/bin/dotnet /data/supervisord/mytest/ConsoleApp1.dllautostart=trueautorestart=truestdout_logfile=/data/supervisord/mytest/5.log[program:mytest3]command=/usr/bin/dotnet /data/supervisord/mytest/ConsoleApp1.dllautostart=trueautorestart=truestdout_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。

[root@k8s-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-test

 《2》 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~
