Django上线部署之uWSGI

环境：
　　1.CentOS 7.2 64位
　　2.SQL Server 2016 Enterprise 64位
　　3.Python 3.6.5 64位
　　4.root用户

要求：
　　按照顺序部署

1.Windows Server 2016 Datacenter 64位操作系统下安装数据库

2.CentOS 7.2 下 Python环境搭建

 1 yum -y install gcc gcc-c++ zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel tree
 2 wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz && tar xf Python-3.6.5.tar.xz
 3 cd Python-3.6.5 && ./configure --prefix=/opt/python365 --enable-shared && make && make install
 4 /opt/python365/bin/python3.6 -V && ln -sf /opt/python365/bin/python3.6 /usr/local/bin/python3 && ln -sf /opt/python365/bin/pip3.6 /usr/local/bin/pip3
 5 pip3 -V && pip3 install virtualenv && ln -sf /opt/python365/bin/virtualenv /usr/local/bin/virtualenv && pip3 install virtualenvwrapper
 6 pip3 -V && pip3 install ipython && ln -sf /opt/python365/bin/ipython3 /usr/local/bin/ipython
 7 echo "PS1=\"[\[\e[32;40m\]\u\[\e[37;40m\]@\h \[\e[33;40m\]>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> \[\e[36;40m\]\w\[\e[0m\]]\\\\$ \n\"" >> /etc/bashrc
 8 echo "set nu" >> /etc/vimrc
 9 echo "export WORKON_HOME=~/envs" >> /etc/bashrc
10 echo "export VIRTUALENVWRAPPER_HOOK_DIR=~/envs" >> /etc/bashrc
11 echo "export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3" >> /etc/bashrc
12 echo "source /opt/python365/bin/virtualenvwrapper.sh" >> /etc/bashrc

3.安装ODBC for SQL Server

 1 # 安装ODBC for SQL Server 驱动
 2 # 实际上是安装如下三个包
 3 # https://packages.microsoft.com/rhel/7/prod/unixODBC-2.3.7-1.rh.x86_64.rpm
 4 # https://packages.microsoft.com/rhel/7/prod/msodbcsql-13.1.9.2-1.x86_64.rpm
 5 # https://packages.microsoft.com/rhel/7/prod/unixODBC-devel-2.3.7-1.rh.x86_64.rpm
 6 curl https://packages.microsoft.com/config/rhel/7/prod.repo > /etc/yum.repos.d/mssql-release.repo
 7 yum remove unixODBC-utf16 unixODBC-utf16-devel
 8 ACCEPT_EULA=Y yum -y install msodbcsql && yum -y install unixODBC-devel
 9 
10 # 安装连接数据库的工具，一般项目上用不到，可不安装
11 ACCEPT_EULA=Y yum install mssql-tools && ln -sf /opt/mssql-tools/bin/bcp /usr/local/bin/bcp && ln -s /opt/mssql-tools/bin/sqlcmd /usr/local/bin/sqlcmd
12 
13 # 以下是Django的settings.py中数据库配置
14 DATABASES = {
15     'default': {
16         'ENGINE': 'sql_server.pyodbc',
17         'NAME': 'db',
18         'USER': 'user',
19         'PASSWORD': 'pwd',
20         'HOST': 'ip',
21         'PORT': '1433',
22         'OPTIONS': {
23             'driver': 'ODBC Driver 13 for SQL Server',
24         },
25     },
26 }
27 
28 DATABASE_CONNECTION_POOLING = True

4.安装uwsgi和uwsgitop(查看uwsgi状态的工具，如果使用securecrt 连接centos，终端需设置成 xterm)

 1 pip install uwsgi uwsgitop && ln -sf /opt/python365/bin/uwsgi /usr/local/bin/uwsgi && ln -sf /opt/python365/bin/uwsgitop /usr/local/bin/uwsgitop
 2 # uwsgi 配置如下：
 3 [uwsgi]
 4 #用户属组ID
 5 gid=1000
 6 #用户ID
 7 uid=1000
 8 #启用主进程
 9 master=true
10 #主进程以root用户启动
11 master-as-root=true
12 #4个进程
13 processes=4
14 #每个进程启用5个线程
15 threads=5
16 #停止运行后清理动态生成的文件
17 vacuum=true
18 #修改当前工作路径，即项目根目录
19 chdir=/srv/www/
20 #wsgi文件路径，可以是相对路径（相对chdir），可以是绝对路径
21 wsgi-file=www/wsgi.py
22 #采用unixsocket通信
23 socket=%(chdir)uwsgi.sock
24 #采用unixsocket通信时，文件权限
25 chmod-socket=666
26 #配合uwsgitop使用，命令：uwsgitopuwsgi.stats查看uWSGI运行状态
27 stats=%(chdir)uwsgi.stats
28 #uwsgi --[reload|stop] uwsgi.pid
29 pidfile=%(chdir)uwsgi.pid
30 #以后台模式运行，并且将日志写入文件
31 daemonize=%(chdir)uwsgi.log
32 #设置日志文件最大为10MB，最后一次日志输出超过这个值则分割
33 log-maxsize=10000000
34 #打印日志添加日期时间前缀
35 log-date=%%F%%H:%%M:%%S
36 #禁用请求日志，只记录交互日志和错误日志，请求日志可在nginx中记录
37 disable-logging=true
38 #请求日志添加内存和虚拟内存信息，disable-logging是false时生效
39 #memory-report=true
40 #Python启用线程，由于GIL的限制，可能没啥用，未测试
41 enable-threads=true
42 #socket监听数，不能超过系统中net.core.somaxconn值
43 listen=1024
44 #主进程死了，其它进程一起死
45 no-orphans=true
46 #进程请求总数累计超过这个值则重启，用reload-on-as和reload-on-rss替换
47 #max-requests=1024
48 #（单位：MB）进程虚拟内存超过限制则重启
49 reload-on-as=1024
50 #（单位：MB）进程物理内存超过限制则重启
51 reload-on-rss=1024
52 #超时重启进程
53 harakiri=60
54 #超时重启进程后打印日志
55 harakiri-verbose=true
56 #（单位：B）
57 buffer-size=32768
58 #（单位：B）
59 post-buffering=32768
60 #（单位：B）限制HTTP请求体60MB
61 limit-post=60000000
62 #静态文件路由
63 static-map=/static=%(chdir)static
64 static-map=/media=%(chdir)media
