docker部署mysql主主备份 haproxy代理（swarm）
1. 环境准备
| 主机 | IP |
|---|---|
| node1 | 192.168.56.100 |
| node2 | 192.168.56.101 |
- 互开防火墙
- 默认安装了docker docker-compose
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.56.100" accept"
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.56.101" accept"
firewall-cmd --reload
firewall-cmd --list-all
1.1. 在3台主机上配置swarm
- 创建 目录
mkdir -p /home/liuhmpackage/liuhm-4.0.0-x16_64 && cd /home/liuhmpackage/liuhm-4.0.0-x16_64
- 在node1上执行：
docker swarm init --advertise-addr 192.168.56.100
返回类似以下内容：
docker swarm join --token SWMTKN-1-614xi9dvksycykobgifxb4pgopc1wwgczwqct5wqkq8zao6tmx-0ds4jj3ozclrr2wukcaoakxso 192.168.56.100:2377
- 在node2上执行上面的返回结果：
docker swarm join --token SWMTKN-1-2c2xopn2rld8oltcof24sue370681ijhbo3bwcqarjlhq9lkea-2g53o5qn2anre4j9puv4hecrn 192.168.0.101:2377
1.2. 创建swarm网络
在node1上执行以下命令：
docker network create -d overlay --subnet 10.0.1.0/24 --attachable liuhm-net
# 检查网络，如果存在表示创建成功
docker network ls | grep liuhm-net
1.3 创建文件
复制下面的sh命令即可获取第二步所需的安装文件
mkdir -p /home/liuhmpackage/liuhm-4.0.0-x16_64/haproxy
cd /home/liuhmpackage/liuhm-4.0.0-x16_64/haproxy
cat > haproxy.cfg << EOF
