一、Docker
安装
1. 使用国内 yum
源#
# yum install -y yum-utils device-mapper-persistent-data lvm2
# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
2. 卸载旧版本的 docker
#
## 如果主机上已经有docker存在且不是想要安装的版本,需要先进行卸载。
# yum remove -y docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine \
container*
3. 安装 Docker20.10
版本#
# yum -y install docker-ce-20.10.12-3.el7 docker-ce-cli-20.10.12-3.el7 vim
4. 设置镜像加速#
# mkdir /etc/docker
# vi /etc/docker/daemon.json
{
"registry-mirrors": ["https://xxxxxxxxx.mirror.aliyuncs.com"]
}
5. 启动 docker
#
# systemctl start docker
# systemctl enable docker
# systemctl status docker
二、Docker-compose
安装
1. Docker-compose
安装#
## github.com 可能访问超时,可以使用下面的获取下载下来后上传服务器即可
# curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# curl -k "https://dl.cactifans.com/zabbix_docker/docker-compose" -o /usr/bin/docker-compose
# chmod a+x /usr/bin/docker-compose
2. 查看 docker-compose
版本#
# docker-compose version
三、Mesos
3主3从
安装
1. 详细的 docker-compose.yml
文件信息#
其他
2个
主机节点修改对应的参数即可
