一、架构环境
1、系统架构
下图摘自《Python自动化运维 技术与最佳实践 刘天斯》
本项目OMS前台使用django+bootstrap+jquery搭建WEB服务,后台使用saltstack实现业务服务器集群的控制管理,两者间通过rpyc进行通讯。(正在计划参照saltstack官方WEBUI项目halite,在django中实现相同功能,调用saltapi,取消rpyc)
2、开发环境
(1)前台:笔记本,win7x64
Python、Pycharm、Django、MySQL、MySQLdb、rpyc、bootstrap、jquery
Xshell 5(SSH远程工具)、Xftp 5(文件传输工具)
(2)后台:虚拟机,centos 6.5,10.188.1.40,saltmaster-40
Python、SaltStack(master+minion+api+ssh)、rpyc
(3)业务主机:虚拟机,centos 6.5,10.188.1.42,saltminion01-41.ewp.com、Salt-Minion
虚拟机,windows server 2008 r2 x64,saltminion02-42、Salt-Minion
3、生产环境
前台:centos 6.5,10.188.1.39,omswebserver-39

二、部署开发环境
参考上一编:OMS开发(二):技术选型
1、前台
Python:http://www.jetbrains.com/pycharm/
PyCharm:https://www.python.org/downloads/ (开发集成环境,可自选其他的)
Django:(CMD)pip install Django==1.8.7 (自带开发WEB服务器runserver)
MySQL:http://www.mysql.com/why-mysql/windows/
MySQLdb:https://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/
rpyc:(CMD)pip install rpyc
bootstrap:http://v3.bootcss.com/getting-started/#download (项目源码中已有)
jquery:http://code.jquery.com/jquery-2.2.0.min.js (项目源码中已有)
2、后台
(1) Python
Centos 6.5 默认安装2.6.6版本,升级为2.7.11:
[root@saltmaster-40 ~]# python -V Python 2.6.6 [root@saltmaster-40 ~]# cd /usr/local/src [root@saltmaster-40 src]# wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz [root@saltmaster-40 src]# tar -zxvf Python-2.7.11.tgz [root@saltmaster-40 src]# cd Python-2.7.11 [root@saltmaster-40 Python-2.7.11]# ./configure --prefix=/usr/local/python27 [root@saltmaster-40 Python-2.7.11]# make [root@saltmaster-40 Python-2.7.11]# make install [root@saltmaster-40 Python-2.7.11]# mv /usr/bin/python /usr/bin/python_old [root@saltmaster-40 Python-2.7.11]# ln -s /usr/local/python27/bin/python /usr/bin/
处理yum兼容问题,使用老版本bin文件
[root@saltmaster-40 ~]# vi /usr/bin/yum #!/usr/bin/python2.6
PIP包管理工具:
https://pip.pypa.io/en/latest/installing/#installing-with-get-pip-py
Python 2 >=2.7.9 or Python 3 >=3.4 已经默认安装PIP
(2) SaltStack
添加YUM源
[root@saltmaster-40 ~]# rpm --import https://repo.saltstack.com/yum/redhat/6/x86_64/latest/SALTSTACK-GPG-KEY.pub [root@saltmaster-40 ~]# vi /etc/yum.repos.d/saltstack.repo [saltstack-repo] name=SaltStack repo for RHEL/CentOS $releasever baseurl=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest enabled=1 gpgcheck=1 gpgkey=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest/$releaseverSALTSTACK-GPG-KEY.pub
安装
[root@saltmaster-40 ~]# yum install salt-master salt-minion salt-api salt-ssh
配置主控服务
[root@saltmaster-40 ~]# vi /etc/salt/master interface: 10.188.1.40 auto_accept: True file_roots: base: - /srv/salt/ [root@saltmaster-40 ~]# mkdir /srv/salt
配置被控服务
[root@saltmaster-40 ~]# vi /etc/salt/minion master: 10.188.1.40 nameid: saltmaster-40
启动服务
[root@saltmaster-40 ~]# chkconfig salt-master on [root@saltmaster-40 ~]# service salt-master start [root@saltmaster-40 ~]# chkconfig salt-minion on [root@saltmaster-40 ~]# service salt-minion start
默认监听4505和4506两个端口
[root@saltmaster-40 ~]# netstat -tnlp|grep 45 [root@saltmaster-40 ~]# iptables -I INPUT -m multiport -p tcp --dports 4505,4506 -j ACCEPT [root@saltmaster-40 ~]# service iptables save
4505(publish_port)为saltstack的消息发布系统
4506(ret_port)为saltstack客户端与服务端通信的端口
(3) rpyc
[root@saltmaster-40 ~]# yum install -y rpycserver
3、业务主机
(1) Windows系统
下载安装包:
Microsoft Visual C++ 2008 x64 SP1 (先安装上)
Salt-Minion-2015.8.3-AMD64-Setup.exe (CMD命令安装)
CMD静默安装:
cd /d D:\download Salt-Minion-2015.8.3-AMD64-Setup.exe /S /master=10.188.1.40 /minion-name=saltminion-42 /start-service=0
修改配置文件:
C:\salt\conf\minion master: 10.188.1.40 id: saltminion02-42
CMD启动服务:
net start salt-minion
(2) Linux系统
[root@saltmonion01-41.ewp.com ~]# rpm --import https://repo.saltstack.com/yum/redhat/6/x86_64/latest/SALTSTACK-GPG-KEY.pub [root@saltmonion01-41.ewp.com ~]# vi /etc/yum.repos.d/saltstack.repo [saltstack-repo] name=SaltStack repo for RHEL/CentOS $releasever baseurl=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest enabled=1 gpgcheck=1 gpgkey=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest/$releaseverSALTSTACK-GPG-KEY.pub [root@saltmonion01-41.ewp.com ~]# yum install salt-minion [root@saltmonion01-41.ewp.com ~]# vi /etc/salt/minion master: 10.188.1.40 nameid: saltminion01-41 [root@saltmonion01-41.ewp.com ~]# chkconfig salt-minion on [root@saltmonion01-41.ewp.com ~]# service salt-minion start

7、Nginx+uwsgi
安装pcre:
轻量级的正则表达式函数库,给nginx的rewrite模块使用
[root@omswebserver-39.ewp.com ~]# cd /usr/local/src [root@omswebserver-39.ewp.com src]# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.34.tar.gz [root@omswebserver-39.ewp.com src]# tar -zxvf pcre-8.34.tar.gz [root@omswebserver-39.ewp.com src]# cd pcre-8.34 [root@omswebserver-39.ewp.com pcre-8.34]# ./configure [root@omswebserver-39.ewp.com pcre-8.34]# make && make install && cd ..
安装nginx:
[root@omswebserver-39.ewp.com src]# wget http://nginx.org/download/nginx-1.5.9.tar.gz [root@omswebserver-39.ewp.com src]# tar -zxvf nginx-1.5.9.tar.gz [root@omswebserver-39.ewp.com src]# cd nginx-1.5.9 [root@omswebserver-39.ewp.com nginx-1.5.9]# ./configure --user=nobody --group=nobody --prefix=/usr/local/nginx --with-http_sutb_status_module --with-cc-opt='-O3' --with-cpu-opt=opteron [root@omswebserver-39.ewp.com nginx-1.5.9]# make && make install && cd ..
安装uwsgi:
快速的、纯C语言开发的、自维护、对开发者友好的WSGI服务器,提供专业的PythonWeb应用发布和开发功能
[root@omswebserver-39.ewp.com src]# wget http://projects.unbit.it/downloads/uwsgi-2.0.4.tar.gz [root@omswebserver-39.ewp.com src]# tar -zxvf uwsgi-2.0.4.tar.gz [root@omswebserver-39.ewp.com src]# cd uwsgi-2.0.4 [root@omswebserver-39.ewp.com uwsgi-2.0.4]# make && cp uwsgi /usr/bin && cd ..
配置Nginx:
[root@omswebserver-39.ewp.com src]# vi /usr/local/nginx/conf/nginx.conf
server { listen 80; server_name oms.ewp.com; location / { uwsgi_pass 127.0.0.1:9000; include uwsgi_params; uwsgi_param UWSGI_CHDIR /data/www/OMS; uwsgi_param UWSGI_SCRIPT django_wsi; access_log off; } location ~* ^.+\.(mpg|avi|mp3|swf|zip|tgz|gz|rar|bz2|doc|xls|xe|ppt|txt|tar|mid|midi|wav|rtf|mpeg)$ { root /data/www/OMS/app/static; access_log off; } }

[uwsgi] socket = 0.0.0.0:9000 master = true pidfile = /usr/local/nginx/uwsgi.pid processes = 8 chdir = /data/www/OMS pythonpath = /data/www profiler = true memory-report = true enable-threads = true logdate = true limit-as = 6048 daemonize = /data/logs/django.log
启动:
[root@omswebserver-39.ewp.com src]# /usr/bin/uwsgi --ini /usr/local/nginx/conf/uwsgi.ini [root@omswebserver-39.ewp.com src]# /usr/local/nginx/sbin/nginx
访问:
四、部署OMS项目
1、下载源码
https://github.com/ywzhou123/OMS
解压后将OMS目录放到你的项目目录,如F:\pycode\OMS
2、添加项目
3、导入数据库
将OMS\SQL\oms.sql导入MySQL数据库,打开mysql命令行界面
mysql> create database oms character set utf8; mysql> grant all on oms.* to 'admin'@'localhost' identified by "abc@123"; mysql> flush privileges; mysql> use oms; mysql> source f:\pycode\OMS\SQL\oms.sql; mysql> quit
上面设置的数据库账号密码在PyCharm中连接数据源时填写:
修改项目配置文件OMS\OMS\config.ini中的数据库连接参数(其他参数暂时无用):
[db]
name = oms
host = localhost
port = 3306
user = admin
pass = abc@123
注意:登陆http://127.0.0.1:8000/admin时默认账号为admin,密码为abc@123,这个不是数据库连接密码,只是设成了一样而已,存于OMS数据库的auth_user表中。
4、启动RPYC
前后台通过rpyc服务进行通讯,后台需要安装rpycserver服务进程。
使用Xftp 5工具将OMS\SaltstackServer\rpycserver.py上传到后台(saltmaster-40.ewp.com)的/home,如果放在其他目录,需要修改rpycserver.sh的第13行(cd /home)。
将rpycserver.sh上传到后台的/etc/init.d/rpycserver,注意这里最好将.sh后缀去掉。
[root@saltmaster-40 ~]# chmod +x /home/rpycserver.py /etc/init.d/rpycserver [root@saltmaster-40 ~]# chkconfig add rpycserver [root@saltmaster-40 ~]# chkconfig on rpycserver [root@saltmaster-40 ~]# service rpycserver start [root@saltmaster-40 ~]# iptables -I INPUT -p tcp --dports 11511 -j ACCEPT [root@saltmaster-40 ~]# service iptables save
测试RPYC,创建一个rpycclient.py脚本,用来测试rpyc传输命令及得到返回结果:
#!/usr/bin/python #coding:utf-8 import rpyc import json def cmd_run(idc,hosts,cmd,args): try: conn=rpyc.connect('10.188.1.40',11511) #连接服务端 conn.root.login('OMuser','KJS23o4ij09gHF734iuhsdfhkGYSihoiwhj38u4h') #登陆账号密码 except Exception,e: return ('connect rpyc server error:'+str(e)) #返回错误 d = {'hosts':hosts,'cmd':cmd,'args':args} j = json.dumps(d) r=conn.root.cmd(j) if r == "{}": result = {'ERROR':'No minions matched the target. No command was sent, no jid was assigned.'} else: result = json.loads(r,"gbk") return result c=cmd_run(3,"saltminion01-41.ewp.com","test.ping","") # c=cmd_run(3,u"saltminion01-41.ewp.com",u"service.get_all",u"") # c=cmd_run(3,u"saltminion02-42",u"cmd.run",u"dir c:\\") print type(c) print c
说明:rpyc只能传输数字和字符串,不能传字典,因此这里做了JSON处理,这里要确保login()中的账号密码一致,项目中的rpyc会根据机房ID来连接同机房下的rpycserver,连接参数存于oms.app_salt_server表中。
