python自动化运维——OMserver平台Web服务端部署过程
1.下载源代码(简单不讲述)2.安装pcre,pcre是一个轻量级的正则表达式函数库，nginx的HTTP Rewrite模块会用到。

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.34.tar.gz
tar -zxvf pcre-8.34.tar.gz
cd pcre-8.34
./configure
make && make install
3.安装nginx.

wget http://nginx.org/download/nginx-1.5.9.tar.gz
tar -zxvf nginx-1.5.9.tar.gz
cd nginx-1.5.9
./configure --user=nobody --group=nobody --prefix=/usr/local/nginx --with-http_stub_status_module --with-cc-opt='-O3' --with-cpu-opt=opteron
make && make install
4.安装MySQL-python.

yum install MySQL-python -y #yum安装方式
wget http://nchc.dl.sourceforge.net/project/mysql-python/mysql-python/1.2.2/MySQL-python-1.2.2.tar.gz
tar -zxvf MySQL-python-1.2.2.tar.gz
cd MySQL-python-1.2.2
python setup.py install
5.安装uwsgi.

wget http://projects.unbit.it/downloads/uwsgi-2.0.4.tar.gz
tar -zxvf uwsgi-2.0.4.tar.gz
cd uwsgi-2.0.4
make
cp uwsgi /usr/bin
6.安装Django.

wget htpp://www.djangoproject.com/m/releases/1.4/Django-1.4.9.tar.gz
tar -zxvf Django-1.4.9.tar.gz
cd Django-1.4.9
python setup.py install
7.配置nginx。修改/usr/local/nginx/conf/nginx.conf,添加以下server域配置：

server {
listen 80;
server_namewww.omserver.com;
location / {
uwsgi_pass 192.168.202.128:9000;
include uwsgi_params;
uwsgi_param UWSGI_CHDIR /data/www/OMserverweb;#项目主目录
uwsgi_param UWSGI_SCRIPT django_wsgi; #此处应与项目目录中的wsgi文件同名
access_log off;
}
location ^~ /static {
root /data/www/OMserverweb;
}
location ~* ^.+\.(mpg|avi|mp3|swf|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|txt|tar|mid|midi|wav|rtf|mpeg)$ {
root /data/www/OMserverweb/static;
access_log off;
}
}
8.配置uwsgi。创建uwsgi配置文件/usr/local/nginx/conf/uwsgi.ini

socket = 0.0.0.0:9000
master = true
pidfile = /usr/local/nginx/uwsgi.pid
processes = 8 #指定进程数
chdir = /data/www/OMserverweb #项目主目录
pythonpath = /data/www
profiler = true
memory-report=true
enable-threads=true
logdate=true
limit-as=6048
daemonize=/data/logs/django.log
注：如果这里需要配置多个django站点，需要创建多个.ini文件分别配置uwsgi,并且需要监听不同端口。9.启动uwsgi和nginx服务。
1
2
/usr/bin/uwsgi --ini /usr/local/nginx/conf/uwsgi.ini
/usr/local/nginx/sbin/nginx
10.项目源码配置
1).将下载的源码放于/data/www/目录下
2).导入数据库结构

mysql> grant all privileges on OMServer.* to omserver_user@'%' identified by 'J8w3jZXSG#y34'
mysql> create OMServer
# mysql -u omserver_user -p < OMServer.sql
注：此处需在mysql配置文件he段中添加default_character_set=utf8,并重启mysql，否则，插入中文数据时会乱码。
3).修改settings.py

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'OMServer',
'USER': 'omserver_user',
'PASSWORD': 'J8w3jZXSG#y34',
'HOST': 'localhost',
'PORT': '3306',
}
}
4).修改主控端rpyc主机IP，autoadmin/views.py

try:
conn=rpyc.connect('192.168.202.132',11511)
conn.root.login('OMuser','KJS23o4ij09gHF734iuhsdfhkGYSihoiwhj38u4h')
except Exception,e:
logger.error('connect rpyc server error:'+str(e))
return HttpResponse('connect rpyc server error:'+str(e))
5).重启uwsgi和nginx
注：由于nginx子进程默认由nobody启动，访问静态文件是可能出现权限禁止错误，需在nginx配置文件中添加userroot;项。
