openEuler安装Docker18.09.0

一、环境

操作系统： openEuler 20.03 LTS SP2
Docker版本：docker-engine-18.09.0
mysql版本：5.7.36
nginx版本：1.18.0

二、准备

# 更新镜像源缓存
dnf makecache
# 修改chrony时间同步配置
sed -i 's/pool  iburst/pool /g' /etc/
# 重启chrony服务
systemctl restart chronyd
# 查看NTP服务器是否在线
chronyc sources

三、安装docker和docker-compose

# 创建docker配置目录
mkdir /etc/docker
# 创建配置文件
tee /etc/docker/ <<-'EOF'
{
  "debug": true,
  "storage-driver": "overlay2",
  "storage-opts":["overlay2.override_kernel_check=true"],
  "graph":"/opt/docker",
  "registry-mirrors": [
  """
  ]
}
EOF
# 使用镜像源安装docker
dnf install docker
# 如果无法联网手动下载以下依赖和程序包使用"rpm -ivh 包名"安装
# /openeuler/openEuler-20.03-LTS-SP2/OS/x86_64/Packages/libcgroup-0.42.2-1.oe1.x86_64.rpm
# /openeuler/openEuler-20.03-LTS-SP2/OS/x86_64/Packages/tar-1.32-2.oe1.x86_64.rpm
# /openeuler/openEuler-20.03-LTS-SP2/OS/x86_64/Packages/docker-engine-18.09.0-203.oe1.x86_64.rpm
# 启动docker
systemctl start docker
# 开启docker开机自动启动
systemctl enable docker
# 查看docker版本信息
docker info
# 下载docker-compose至/usr/local/bin/docker-compose
curl -L "/docker/compose/releases/download/v2.2.2/docker-compose-linux-x86_64" -o /usr/local/bin/docker-compose
# 允许/usr/local/bin/docker-compose执行
chmod +x /usr/local/bin/docker-compose
# 查看docker-compose版本
docker-compose --version

四、使用docker运行mysql和nginx

# 创建程序目录
mkdir -p /opt/myapp
# 进入目录
cd /opt/myapp
# 创建mysql配置文件目录
mkdir -p ./mysql/conf
# 创建mysql数据库文件目录
mkdir -p ./mysql/data
# 创建日志文件目录
mkdir -p ./mysql/logs
# 创建mysql配置文件
tee ./mysql/conf/ <<-'EOF'

五、启动容器

# 创建并后台启动容器
docker-compose up -d
# 查看nginx日志
docker-compose logs nginx
# 查看mysql日志
docker-compose logs mysql
# docker-compose 常用操作
# 停止容器
# docker-compose stop
# 启动容器
# docker-compose start
# 删除容器
# docker-compose rm nginx
# docker-compose rm mysql

六、访问测试

# 测试nginx
curl http://localhost
# 安装mariadb客户端
dnf install mariadb
# 链接mysql
mysql -h 127.0.0.1 -u root -p
# 查看数据库列表
show databases;
# 退出mysql客户端
exit;
