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

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
