docker-compose管理lnmp

安装docker-compose

1. curl -L https://get.daocloud.io/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
2. chmod +x /usr/local/bin/docker-compose //设置可执行权限

创建并启动容器

docker-compose -f docker-compose-linux.yml up -d --force-recreate --remove-orphans

容器查看

docker ps

测试

vim /data/www/zhangdetalk_blog_admin/index.php
<?php
echo "Hello World";
$conn = mysqli_connect('数据库容器名字','dbuser','dbpw');
if($conn){
 echo '数据库连接成功！';
}else{
 echo '数据库连接失败！';
}
phpinfo();
?>
