我有一个脚本将ubuntu服务器上的docker wordpress和mysql服务器一起安装。此脚本在本地计算机上的VMWare上的ubuntu服务器16.04和18.04上均可正常运行。此脚本适用于AwS lightail ubuntu服务器16.04实例,但不适用于18.04。我在脚本命令上没有任何错误。整个过程成功完成,但是当我检查运行容器时,我看到mysql容器正在重新启动。这仅在AWS lightail ubuntu 18.04实例上发生。不知道为什么。有人可以帮忙吗?脚本如下:
#!/bin/bash
apt-get -y update
apt-get -y install apt-transport-https ca-certificates curl software-
properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
apt-key fingerprint 0EBFCD88
add-apt-repository "deb [arch=amd64]
https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
apt-get -y update
apt-get -y install docker-ce docker-compose
mkdir wordpress
cd wordpress
echo "file_uploads = On

我在数据库环境中发现了WORDPRESS_DB_HOST问题:db:3306。我把我的yml脚本降低到基本最低要求,并且有效。我也认为mysql与AWS Lightail ubuntu 18.04服务器存在问题。 Mariadb正常运行。我在AWS lightail ubuntu服务器18.04上最终的docker-compose.yml脚本是:
wordpress:
image: wordpress
links:
- wordpress_db:mysql
ports:
- 80:80
volumes:
- ./uploads.ini:/usr/local/etc/php/conf.d/uploads.ini
wordpress_db:
image: mariadb
environment:
MYSQL_ROOT_PASSWORD: user123
