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-release 2 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 [[email protected] ~]# 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-3.3.5 10 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 [[email protected] ~]# pip install --upgrade pip 13 Collecting pip 14 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: pip 17 Found existing installation: pip 10.0.1 18 Uninstalling pip-10.0.1: 19 Successfully uninstalled pip-10.0.1 20 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 [[email protected] supervisor]# pwd 2 /data/supervisor 3 [[email protected] supervisor]# echo_supervisord_conf > ./supervisord.conf 4 [[email protected] supervisor]# ls 5 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 ，
; 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 ".

;[group:thegroupname]
;programs=progname1,progname2 ; each refers to ‘x‘ in [program:x] definitions
;priority=999 ; the relative start priority (default 999)
; The [include] section can just contain the "files" setting. This
; setting can list multiple files (separated by whitespace or
; newlines). It can also contain wildcards. The filenames are
; interpreted as relative to this file. Included files *cannot*
; include files themselves.
;[include]
;files = relative/directory/*.ini
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 default port=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。
[[email protected] 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。
[[email protected]master supervisord]# supervisorctl help default 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。
[[email protected] conf]# tail consoleapp3.ini [program:consoleapp3] command=/usr/bin/dotnet /data/supervisord/ConsoleApp3/ConsoleApp3.dll autostart=true autorestart=true stdout_logfile=/data/supervisord/ConsoleApp3/1.log
执行以下update命令让supervisor重新加载配置文件。
[[email protected] 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.dll autostart=true autorestart=true stdout_logfile=/data/supervisord/mytest/4.log [program:mytest2] command=/usr/bin/dotnet /data/supervisord/mytest/ConsoleApp1.dll autostart=true autorestart=true stdout_logfile=/data/supervisord/mytest/5.log [program:mytest3] command=/usr/bin/dotnet /data/supervisord/mytest/ConsoleApp1.dll autostart=true autorestart=true 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。
[[email protected]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~
