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

 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
 wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz && tar xf Python-3.6.5.tar.xz
 cd Python-3.6. && ./configure --prefix=/opt/python365 --enable-shared && make && make install
 /opt/python365/bin/python3. -V && ln -sf /opt/python365/bin/python3. /usr/local/bin/python3 && ln -sf /opt/python365/bin/pip3. /usr/local/bin/pip3
 pip3 -V && pip3 install virtualenv && ln -sf /opt/python365/bin/virtualenv /usr/local/bin/virtualenv && pip3 install virtualenvwrapper
 pip3 -V && pip3 install ipython && ln -sf /opt/python365/bin/ipython3 /usr/local/bin/ipython
 echo "PS1=\"[\[\e[32;40m\]\u\[\e[37;40m\]@\h \[\e[33;40m\]>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> \[\e[36;40m\]\w\[\e[0m\]]\\\\$ \n\"" >> /etc/bashrc
 echo "set nu" >> /etc/vimrc
 echo "export WORKON_HOME=~/envs" >> /etc/bashrc
 echo "export VIRTUALENVWRAPPER_HOOK_DIR=~/envs" >> /etc/bashrc
 echo "export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3" >> /etc/bashrc
 echo "source /opt/python365/bin/virtualenvwrapper.sh" >> /etc/bashrc

3.安装ODBC for SQL Server

 # 安装ODBC for SQL Server 驱动
 # 实际上是安装如下三个包
 # https://packages.microsoft.com/rhel/7/prod/unixODBC-2.3.7-1.rh.x86_64.rpm
 # https://packages.microsoft.com/rhel/7/prod/msodbcsql-13.1.9.2-1.x86_64.rpm
 # https://packages.microsoft.com/rhel/7/prod/unixODBC-devel-2.3.7-1.rh.x86_64.rpm
 curl https://packages.microsoft.com/config/rhel/7/prod.repo > /etc/yum.repos.d/mssql-release.repo
 yum remove unixODBC-utf16 unixODBC-utf16-devel
 ACCEPT_EULA=Y yum -y install msodbcsql && yum -y install unixODBC-devel

 # 安装连接数据库的工具，一般项目上用不到，可不安装
 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

 # 以下是Django的settings.py中数据库配置
 DATABASES = {
     'default': {
         'ENGINE': 'sql_server.pyodbc',
         'NAME': 'db',
         'USER': 'user',
         'PASSWORD': 'pwd',
         'HOST': 'ip',
         'PORT': '',
         'OPTIONS': {
             'driver': 'ODBC Driver 13 for SQL Server',
         },
     },
 }

 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)

 pip install uwsgi uwsgitop && ln -sf /opt/python365/bin/uwsgi /usr/local/bin/uwsgi && ln -sf /opt/python365/bin/uwsgitop /usr/local/bin/uwsgitop
 # uwsgi 配置如下：
 [uwsgi]
 #用户属组ID
 gid=
 #用户ID
 uid=
 #启用主进程
 master=true
 #主进程以root用户启动
 master-as-root=true
 #4个进程
 processes=
 #每个进程启用5个线程
 threads=
 #停止运行后清理动态生成的文件
 vacuum=true
 #修改当前工作路径，即项目根目录
 chdir=/srv/www/
 #wsgi文件路径，可以是相对路径（相对chdir），可以是绝对路径
 wsgi-file=www/wsgi.py
 #采用unixsocket通信
 socket=%(chdir)uwsgi.sock
 #采用unixsocket通信时，文件权限
 chmod-socket=
 #配合uwsgitop使用，命令：uwsgitopuwsgi.stats查看uWSGI运行状态
 stats=%(chdir)uwsgi.stats
 #uwsgi --[reload|stop] uwsgi.pid
 pidfile=%(chdir)uwsgi.pid
 #以后台模式运行，并且将日志写入文件
 daemonize=%(chdir)uwsgi.log
 #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
 log-maxsize=
 #打印日志添加日期时间前缀
 log-date=%%F%%H:%%M:%%S
 #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
 disable-logging=true
 #请求日志添加内存和虚拟内存信息，disable-logging是false时生效
 #memory-report=true
 #Python启用线程，由于GIL的限制，可能没啥用，未测试
 enable-threads=true
 #socket监听数，不能超过系统中net.core.somaxconn值
 listen=
 #主进程死了，其它进程一起死
 no-orphans=true
 #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
 #max-requests=
 #（单位：MB）进程虚拟内存超过限制则重启
 reload-on-as=
 #（单位：MB）进程物理内存超过限制则重启
 reload-on-rss=
 #超时重启进程
 harakiri=
 #超时重启进程后打印日志
 harakiri-verbose=true
 #（单位：B）
 buffer-size=
 #（单位：B）
 post-buffering=
 #（单位：B）限制HTTP请求体60MB
 limit-post=
 #静态文件路由
 static-map=/static=%(chdir)static
 static-map=/media=%(chdir)media

5.安装nginx

 wget http://nginx.org/download/nginx-1.16.1.tar.gz
 tar -zxvf nginx-1.16..tar.gz
 cd nginx-1.16./ && ./configure --prefix=/opt/nginx --with-http_ssl_module --with-http_gzip_static_module && make && make install
 /opt/nginx/sbin/nginx -V && ln -sf /opt/nginx/sbin/nginx /usr/local/bin/nginx

     gzip_types *;

     log_format main '$time_iso8601|$http_x_forwarded_for|$remote_addr|$remote_user|'
                     '$request_length|$body_bytes_sent|$request_time|$upstream_response_time|'
                     '$status|"$request"|"$http_referer"|"$http_user_agent"';

     server {
         listen ;
         server_name 192.168.70.110;
         charset utf-;
         client_max_body_size 60M;

         location /media {
             alias /srv/www/media;
             access_log logs/static.log main;
             expires 30d;
         }

         location /static {
             alias /srv/www/static;
             access_log logs/static.log main;
             expires 30d;
         }

         location / {
             uwsgi_pass  unix:///srv/www/uwsgi.sock;
             include uwsgi_params;
             access_log logs/access.log main;
             limit_conn conn_ip ;
             limit_req zone=req_ip burst=;
         }

         error_page     /50x.html;
         location = /50x.html {
             root html;
         }
     }
 }

6.安装Redis
