bash 复制代码

sudo yum install -y yum-utils && sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo && sudo yum -y install consul

#添加consul配置文件
nano /etc/consul.d/server.json
{
    "server": true,
    "bootstrap": true,
    "advertise_addr": "192.168.31.168",
    "ui_config": {
        "enabled": true
    },
    "data_dir": "/data/consul",
    "log_level": "INFO",
    "addresses": {
        "http": "0.0.0.0"
    },
    "ports": {
        "http": 8500
    }
}
#启动
sudo chmod 777 /data/consul
systemctl start consul && systemctl enable consul

配置开机启动：

bash 复制代码

nano /etc/systemd/system/consul.service

Docker版本7天没有使用后，会出现集群错误，所以部属Linux版本开发比较好

$ERROR$ agent: startup error: error="refusing to rejoin cluster because server has been offline for more than the configured server_rejoin_age_max (168h0m0s) - consider wiping your data dir"
