Docker-Compose是一个部署多个容器的简单但是非常必要的工具.安装Docker-Compose之前，请先安装 python-pip
一、安装 python-pip [root@workbench-test ~]# pip -V -bash: pip: command not found [root@workbench-test ~]# yum install python-pip [root@workbench-test ~]# yum -y install epel-release [root@workbench-test ~]# yum install python-pip [root@workbench-test ~]# pip install --upgrade pip [root@workbench-test ~]# pip -V pip 10.0.1 from /usr/lib/python2.7/site-packages/pip (python 2.7) 二、安装Docker Compose [root@workbench-test ~]# pip install docker-compose --------------------------------------------------------------------------------------- 如果报错： ReadTimeoutError: HTTPSConnectionPool(host='pypi.python.org', port=443): Read timed out 解决： # pip --default-timeout=200 install -U docker-compose -------------------------------------------------------------------------------------- 如果执行中报错： Setup script exited with error: command 'gcc' failed with exit status 1异常 这是没有正确安装Python开发环境导致，解决如下： # yum install python-devel # yum install libevent-devel # pip install gevent # yum install groupinstall 'development tools' -------------------------------------------------------------------------------------- 检验docker-compose是否安装成功 [root@workbench-test ~]# docker-compose --version docker-compose version 1.21.2, build a133471 -------------------------------------------------------------------------------------- 如果报错： pkg_resources.DistributionNotFound: backports.ssl-match-hostname>=3.5 解决方法：更新backports.ssl-match-hostname的版本，在终端输入命令 # pip install --upgrade backports.ssl_match_hostname
Docker-compose常用命令
# docker-compose --help 命令可以查看到命令列表 build Build or rebuild services bundle Generate a Docker bundle from the Compose file config Validate and view the Compose file create Create services down Stop and remove containers, networks, images, and volumes events Receive real time events from containers exec Execute a command in a running container help Get help on a command images List images kill Kill containers logs View output from containers pause Pause services port Print the public port for a port binding ps List containers pull Pull service images push Push service images restart Restart services rm Remove stopped containers run Run a one-off command scale Set number of containers for a service start Start services stop Stop services top Display the running processes unpause Unpause services up Create and start containers version Show the Docker-Compose version information ================================================================================== docker-compose up -d nginx 构建建启动nignx容器 docker-compose exec nginx bash 登录到nginx容器中 docker-compose down 删除所有nginx容器,镜像 docker-compose ps 显示所有容器 docker-compose restart nginx 重新启动nginx容器 docker-compose run --no-deps --rm php-fpm php -v 在php-fpm中不启动关联容器，并容器执行php -v 执行完成后删除容器 docker-compose build nginx 构建镜像 docker-compose build --no-cache nginx 不带缓存的构建。 docker-compose logs nginx 查看nginx的日志 docker-compose logs -f nginx 查看nginx的实时日志 ================================================================================== docker-compose config -q 验证（docker-compose.yml）文件配置，当配置正确时，不输出任何内容，当文件配置错误，输出错误信息。 docker-compose events --json nginx 以json的形式输出nginx的docker日志 docker-compose pause nginx 暂停nignx容器 docker-compose unpause nginx 恢复ningx容器 docker-compose rm nginx 删除容器（删除前必须关闭容器） docker-compose stop nginx 停止nignx容器 docker-compose start nginx 启动nignx容器
