Linux部署Django环境
一、安装python3可能使用的依赖
[root@instance-xu9puhyr ~]# yum -y install gcc [root@instance-xu9puhyr ~]# yum -y groupinstall 'Development Tools' [root@instance-xu9puhyr ~]# yum install -y ncurses-libs zlib-devel mysql-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
二、进入tmp目录
[root@instance-xu9puhyr ~]# cd / [root@instance-xu9puhyr /]# cd tmp/ 下载到tmp目录 python3.6.7 [root@instance-xu9puhyr tmp]# wget https://www.python.org/ftp/python/3.6.7/Python-3.6.7.tgz 解压python3.6.7 [root@instance-xu9puhyr tmp]# tar xf Python-3.6.7.tgz 进入python目录 [root@instance-xu9puhyr tmp]# cd Python-3.6.7 使用gcc编译python3.6.7 [root@instance-xu9puhyr Python-3.6.7]# ./configure 安装python3.6.7 安装目录：/usr/local/bin/python3.6 [root@instance-xu9puhyr Python-3.6.7]# make [root@instance-xu9puhyr Python-3.6.7]# make intsall 备份系统自带python2.7 系统自带命令python目录：/usr/bin/python 更改为/usr/bin/python-2.7.backup [root@instance-xu9puhyr ~]# mv /usr/bin/python /usr/bin/python-2.7.backup 创建系统命令（软链接）将系统命令python指定目录到/usr/local/bin/python3.6 以及pip3 [root@instance-xu9puhyr /]# ln -s /usr/local/bin/python3.6 /usr/bin/python [root@instance-xu9puhyr /]# ln -s /usr/local/bin/pip3 /usr/bin/pip3 由于yum依赖于python2，系统命令被修改所以需要告诉yum命令指定python2 使用i修改文件 esc退出修改 ：wq强制保存文件修改 [root@instance-xu9puhyr /]# vi /usr/bin/yum #!/usr/bin/python 打开yum文件修改头部===查看目录/usr/bin/中python2对应的文件 #!/usr/bin/python2.6 看系统有没有这个文件有则修改头部 目录：/usr/libexec/urlgrabber-ext-down [root@instance-xu9puhyr /]# vi /usr/libexec/urlgrabber-ext-down #!/usr/bin/python 打开yum文件修改头部===查看目录/usr/bin/中python2对应的文件 #!/usr/bin/python2.6 使用yum -v检查是否yum还存在报错
三、根目录创建python3.6虚拟环境
[root@instance-xu9puhyr /]# python -m venv /myblog/ 进入虚拟环境的bin目录 [root@instance-xu9puhyr /]# cd myblog/bin 进入虚拟环境 [root@instance-xu9puhyr bin]# source activate 查看环境里的模块 (myblog) [root@instance-xu9puhyr bin]# pip freeze 安装django2.1.0版本 (myblog) [root@instance-xu9puhyr bin]# pip install django==2.1.0 安装Gunicorn“绿色独角兽”是一个被广泛使用的高性能的Python WSGI UNIX HTTP服务器 (myblog) [root@instance-xu9puhyr bin]# pip install gunicorn (myblog) [root@instance-xu9puhyr bin]# pip install pymysql
四、安装nginx环境
(myblog) [root@instance-xu9puhyr bin]# yum -y install nginx (myblog) [root@instance-xu9puhyr bin]# service nginx start (myblog) [root@instance-xu9puhyr bin]# systemctl start nginx.service (myblog) [root@instance-xu9puhyr bin]# systemctl enable nginx.service
五、修改django项目settings文件
import os # Build paths inside the project like this: os.path.join(BASE_DIR, ...) BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) # Quick-start development settings - unsuitable for production # See https://docs.djangoproject.com/en/2.1/howto/deployment/checklist/ # SECURITY WARNING: keep the secret key used in production secret! SECRET_KEY = '6m1wv5553o(vc1^_wr_gq5^=ma6_@a5ax8tsh#lx$jyya8)x5)' # SECURITY WARNING: don't run with debug turned on in production! DEBUG = False ALLOWED_HOSTS = ["*"] # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'DB', 'pubadmin', 'student', 'Sale', ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] ROOT_URLCONF = 'ProjectCRM.urls' TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates'), os.path.join(BASE_DIR, 'pubadmin/templates')] , 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] WSGI_APPLICATION = 'ProjectCRM.wsgi.application' # Database # https://docs.djangoproject.com/en/2.1/ref/settings/#databases DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'xxx', #你的数据库名称 'USER': 'xxx', #你的数据库用户名 'PASSWORD': 'xxx', #你的数据库密码 'HOST': 'xxxx', #你的数据库主机，留空默认为localhost 'PORT': 'xxx', #你的数据库端口 } } # Password validation # https://docs.djangoproject.com/en/2.1/ref/settings/#auth-password-validators AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, ] # Internationalization # https://docs.djangoproject.com/en/2.1/topics/i18n/ LANGUAGE_CODE = 'zh-Hans' TIME_ZONE = 'Asia/Shanghai' USE_I18N = True USE_L10N = True USE_TZ = True # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/2.1/howto/static-files/ STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR,'static'), os.path.join(BASE_DIR, 'pubadmin/static'), ) # MEDIA_URL = '/media/' # MEDIAFILES_DIRS = ( # os.path.join(BASE_DIR,'media'), # os.path.join(BASE_DIR, 'pubadmin/media'), # ) LOGIN_URL = '/pubadmin/login/'
六、修改ngnix文件
# For more information on configuration, see: # * Official English Documentation: http://nginx.org/en/docs/ # * Official Russian Documentation: http://nginx.org/ru/docs/ user nginx; worker_processes auto; error_log /var/log/nginx/error.log; pid /run/nginx.pid; # Load dynamic modules. See /usr/share/nginx/README.dynamic. include /usr/share/nginx/modules/*.conf; events { worker_connections 1024; } http { log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; include /etc/nginx/mime.types; default_type application/octet-stream; # Load modular configuration files from the /etc/nginx/conf.d directory. # See http://nginx.org/en/docs/ngx_core_module.html#include # for more information. include /etc/nginx/conf.d/*.conf; server { listen 80 default_server; listen [::]:80 default_server; server_name _; root /mysite/ProjectCRM; # Load configuration files for the default server block. include /etc/nginx/default.d/*.conf; location /static/ { alias /mysite/ProjectCRM/static/; } location /media/ { alias /mysite/ProjectCRM/media/; } location / { root /mysite/ProjectCRM; proxy_pass http://127.0.0.1:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } error_page 404 /404.html; location = /40x.html { } error_page 500 502 503 504 /50x.html; location = /50x.html { } } # Settings for a TLS enabled server. # # server { # listen 443 ssl http2 default_server; # listen [::]:443 ssl http2 default_server; # server_name _; # root /usr/share/nginx/html; # # ssl_certificate "/etc/pki/nginx/server.crt"; # ssl_certificate_key "/etc/pki/nginx/private/server.key"; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 10m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # # # Load configuration files for the default server block. # include /etc/nginx/default.d/*.conf; # # location / { # } # # error_page 404 /404.html; # location = /40x.html { # } # # error_page 500 502 503 504 /50x.html; # location = /50x.html { # } # } }
七、重启ngnix服务
(mysite) [root@instance-xu9puhyr bin]# systemctl restart nginx.service 进入项目目录 (mysite) [root@instance-xu9puhyr mysite]# cd ProjectCRM/ 启动项目 (mysite) [root@instance-xu9puhyr ProjectCRM]# gunicorn ProjectCRM.wsgi:application -b 127.0.0.1:8000 -D
八、查看gunicorn进程
(mysite) [root@instance-xu9puhyr ProjectCRM]# pstree -ap|grep gunicorn (mysite) [root@instance-xu9puhyr ProjectCRM]# kill -9 进程号 kill -HUP 进程号
