tidb数据库3主机分布式集群docker-compose离线部署

news 2026/8/15 16:24:07

#3台机器，每台部署1pd，1tikv，1tidb；共3pd，3tikv，3tidb

#外加nginx负载均衡单节点dockers-compose部署

#tidb的3台机器192.168.1.41；192.168.1.42；192.168.1.43

#nginx单节点192.168.1.24

#首先自行初始化服务器关闭防火墙、SElinux、设置时间同步等，云服务器可以直接开始部署

#部署docker和dockers-compose，本次选择docker-27.3.1和docker-compose-2.29.7

#下载地址：https://download.docker.com/linux/static/stable/x86_64/

#上传docker-27.3.1.tgz到/opt下

cd /opt && tar -xvf docker-27.3.1.tgz

#复制所有解压出来的文件进/usr/bin

cp /opt/docker/* /usr/bin/

vim /etc/systemd/system/docker.service #复制写入下述配置 [Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service Wants=network-online.target [Service] Type=notify ExecStart=/usr/bin/dockerd ExecReload=/bin/kill -s HUP $MAINPID LimitNOFILE=infinity LimitNPROC=infinity TimeoutStartSec=0 Delegate=yes KillMode=process Restart=on-failure StartLimitBurst=3 StartLimitInterval=60s [Install] WantedBy=multi-user.target

#完成写入配置后给予权限

chmod +x /etc/systemd/system/docker.service

systemctl daemon-reload

#启动并设置开机自启docker

systemctl enable docker --now

#清除安装文件

rm -rf /opt/docker

#下载docker-compose，下载地址：https://github.com/docker/compose/releases

#下滑选择所需版本，Assets点击下拉菜单，根据系统和cpu架构选择下载，直接下载二进制文件

#linux系统x86架构本次选择下载docker-compose-linux-x86_64

#上传docker-compose-linux-x86_64到/opt下

cd /opt/ && mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

#设置docker下拉镜像加速 vim /etc/docker/daemon.json #写入多条加速配置 { "registry-mirrors": [ "https://docker.211678.top", "https://docker.1panel.live", "https://hub.rat.dev", "https://docker.m.daocloud.io", "https://do.nark.eu.org", "https://dockerpull.com", "https://dockerproxy.cn", "https://docker.awsl9527.cn" ] } #保存生效配置

systemctl daemon-reload

systemctl restart docker

#docker部署完成

#tidb的dockers镜像下载，本次选择v8.1.2版本

#离线环境需要先在有互联网环境的docker机器上先下载镜像，再上传至离线环境 docker pull pingcap/tikv:v8.1.2 docker pull pingcap/tidb:v8.1.2 docker pull pingcap/pd:v8.1.2 #本地保存镜像 docker save pingcap/tikv:v8.1.2 > /opt/tikv.tar docker save pingcap/tidb:v8.1.2 > /opt/tidb.tar docker save pingcap/pd:v8.1.2 > /opt/pd.tar #上传三个包到41，42，43节点的/opt下,在每个节点执行加载镜像 docker load < /opt/tikv.tar docker load < /opt/tidb.tar docker load < /opt/pd
