部署django+uwsgi+Virtualenv+nginx+supervisor详细步骤
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel gcc gcc-c++ # yum方法安装的，可以用 yum list installed 查找，如果是查找指定包，用 yum list installed | grep "软件名或者包名"
1、下载python安装包
wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
2、 使用root权限打开终端，进行解压缩操作
tar -zxvf Python-3.6.5.tgz
3、将目录重命名
mv Python-3.6.5 python3.6
4、修改setup文件，启动ssl模块
vi /root/python3.6/Modules/Setup.dist
#使用/Socket 找到所在行 #修改结果如下： # Socket module helper for socket(2) _socket socketmodule.c timemodule.c # Socket module helper for SSL support; you must comment out the other # socket line above, and possibly edit the SSL variable: SSL=/usr/local/ssl _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto
5、进入python3.6目录编译安装
./configure --with-ssl --prefix=/opt/python3.6 # 目录/opt/python3.6可以根据自己的喜好随意选择，此目录为python的真正安装目录
6、make&make install
make & make install
7、创建软连接
ln -s /opt/python3.6/bin/python3.6 /usr/bin/python3
ln -s /opt/python3.6/bin/pip3 /usr/bin/pip3
#更改国内源 pip3 install pip -U pip3 config set global.index-url https://mirrors.aliyun.com/pypi/simple/
1、安装 virtualenv 模块
pip3 install virtualenv==16.7.9 #使用此版本，最新版有bug
2、查看版本
virtualenv --version
3、查看路径
find / -name virtualenv
4、创建软连接
ln -s /opt/python3.6/bin/virtualenv /usr/bin/virtualenv #/opt/python3.6/bin/virtualenv替换成你找到路径
5、创建虚拟环境，并命名
virtualenv --no-site-packages venv #venv是虚拟环境的名称
6、激活进入虚拟环境
source venv/bin/activate
7、退出
deactivate
8、其他命令
worken #查看虚拟环境目录 workon venv2 #切换虚拟环境 rmvirtualenv venv #删除虚拟环境
1、安装
pip3 install uwsgi
2、创建软路由
ln -s /opt/python3.6/bin/uwsgi /usr/bin/uwsgi
3、配置
路径：/opt/rpa_server/server_uwsgi.ini
[uwsgi] # Django-related settings # the base directory (full path) chdir = /opt/rpa_server # Django's wsgi file module = rpa_server.wsgi enable-threads = true
lazy-apps=true #部署tensorflow时需要添加此参数，不然请求会卡死 # process-related settings # master master = true # maximum number of worker processes processes = 1 threads = 10 # the socket (use the full path to be safe socket = 0.0.0.0:8080 #http = 0.0.0.0:9000 # ... with appropriate permissions - may be needed # chmod-socket = 664 # clear environment on exit vacuum = true home = /root/venv daemonize = /opt/rpa_server/maple_uwsgi.log
启动
uwsgi --ini server_uwsgi.ini
#杀死进程 ps -A|grep uwsgi kill -9 uwsgi的进程id
yum install epel-release -y
yum install nginx -y
2、配置
路径：/etc/nginx/conf.d/rpa_server.conf
upstream rpa { server 0.0.0.0:8080; # for a web port socket (we'll use this first) } server { listen 8000; server_name ; #client_max_body_size 75M; access_log logs/rpa_server_access.log main; location / { uwsgi_pass rpa; include /etc/nginx/uwsgi_params; } location /static { alias /opt/rpa_server/static; } error_page 400 403 404 405 505 500 501 502 503 504 /404.html; location = /404.html { root /opt/rpa_server/templates/; } }
# nginx扩展 django多路径static文件，nginx的配置方法 1.设置static_root ``` #在setting中设置 STATIC_ROOT=os.path.join(BASE_DIR,"static") ``` 2.创建新的static目录 ``` #该命令会把当前项目的所有静态文件统一放在STATIC_ROOT python manage.py collectstatic ``` 3.然后nginx直接配置STATIC_ROOT ``` location /static { alias <STATIC_ROOT的实际目录> } ```
3、启动
启动
systemctl start nginx
停止
systemctl stop nginx
重启
systemctl restart nginx
查看状态
systemctl status nginx
6.安装supervisor
1.安装
yum install -y supervisor
2.启动
#启动supervisord systemctl start supervisord #查看状态 systemctl status supervisord
3.修改
#修改配置文件 vim /etc/supervisord.conf #把[inet_http_server]模块的注释去掉 #并修改IP、用户名与密码 [inet_http_server] port=0.0.0.0:9001 username=root password=123456
4.重新加载
#重新加载配置文件 supervisorctl reload
5.配置需要管理的进程（重点）
cat /etc/supervisord.conf
#在/etc/supervisord.d 创建配置文件rpa_uwsgi.ini [program:uwsgi] directory = /root ;命令执行目录(这里是存放rpa_server_uwsgi.ini) command = /root/venv/bin/uwsgi /root/rpa_server_uwsgi.ini ;启动命令 autostart = true ;在supervisord启动的时候也启动 startsecs = 5 ;启动5秒后没有异常退出，就当作已经正常启动了 autorestart = true ;程序异常退出后自动重启 startretries = 3 ;启动失败自动重试次数，默认是3 user = root ;哪个用户启动 redirect_stderr = true ;把stderr重定向到stdout，默认false stdout_logfile_maxbytes = 20MB ;stdout日志文件大小，默认50MB stdout_logfile_backups = 20 ;stdout日志文件备份数 stdout_logfile = /opt/supervisor/logs/rpa_uwsgi_stdout.log
6.启动
#重新加载 supervisorctl reload #启动 supervisorctl start uwsgi 对应[program:uwsgi]可以自己随便定义
7.开启防火墙端口
防火墙添加规则 firewall-cmd --permanent --zone=public --add-port=8080/tcp 加载 firewall-cmd --reload 重启 systemctl restart firewalld.service
8.更换yum源
1. 查看yum源信息: yum repolist 2. 安装base reop源 cd /etc/yum.repos.d 3. 接着备份旧的配置文件 sudo mv CentOS-Base.repo CentOS-Base.repo.bak 4. 下载阿里源的文件 sudo wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/Centos-7.repo 5. 清理缓存 yum clean all 6. 重新生成缓存 yum makecache 7. 再次查看yum源信息 yum repolist
