consul 集群搭建
consul 集群搭建
一、三台机器
基本信息
192.168.80.128
192.168.80.129
192.168.80.130
二、下载consul
wget https://releases.hashicorp.com/consul/1.9.5/consul_1.9.5_linux_amd64.zip
# 解压出来就是一个二进制文件
三、三台机器分别创建目录和文件
mkdir /opt/consul/bin/
# 拷贝解压的二进制文件至 /opt/consul/bin/
mkdir /opt/consul/data/
mkdir /opt/consul/logs/
mkdir /opt/consul/conf/
四、配置
192.168.80.128 机器配置 consul.json
{
"datacenter": "djx-test",
"data_dir": "/opt/consul/data",
"log_level": "INFO",
"node_name": "192.168.80.128",
"server": true,
"ui": true,
"bootstrap_expect": 1,
"bind_addr": "192.168.80.128",
"client_addr": "0.0.0.0",
"retry_join": ["192.168.80.129","192.168.80.130"],
"retry_interval": "3s",
"raft_protocol": 3,
"enable_debug": false,
"rejoin_after_leave": true,
"enable_syslog": false,
"telemetry": {
"statsite_address": "127.0.0.1:9125"
}
}
192.168.80.129 配置 consul.json
{
"datacenter": "djx-test",
"data_dir": "/opt/consul/data",
"log_level": "INFO",
"node_name": "192.168.80.129",
"server": true,
"ui": true,
"bootstrap_expect": 1,
"bind_addr": "192.168.80.129",
"client_addr": "0.0.0.0",
"retry_join": ["192.168.80.128","192.168.80.130"],
"retry_interval": "3s",
"raft_protocol": 3,
"enable_debug": false,
"rejoin_after_leave": true,
"enable_syslog": false,
"telemetry": {
"statsite_address": "127.0.0.1:9125"
}
}
192.168.80.130 配置 consul.json
{
"datacenter": "djx-test",
"data_dir": "/opt/consul/data",
"log_level": "INFO",
"node_name": "192.168.80.130",
"server": true,
"ui": true,
"bootstrap_expect": 1,
"bind_addr": "192.168.80.130",
"client_addr": "0.0.0.0",
"retry_join": ["192.168.80.128","192.168.80.129"],
"retry_interval": "3s",
"raft_protocol": 3,
"enable_debug": false,
"rejoin_after_leave": true,
"enable_syslog": false,
"telemetry": {
"statsite_address": "127.0.0.1:9125"
}
}
五、三台机器都配置成系统服务
/usr/lib/systemd/system/consul.service
[Unit]
Description=consul
After=network.target
[Service]
LimitNOFILE=32768
Type=simple
Restart=on-failure
ExecStart=/opt/consul/bin/consul agent -config-dir /opt/consul/conf/ -http-port=8500 -log-file=/opt/consul/logs/consul.log
[Install]
WantedBy=multi-user.target
六、启动服务并添加到系统服务
systemctl start consul
systemctl enable consul
七、查看集群节点
consul members
/ # consul members
Node Address Status Type Build Protocol DC Segment
192.168.80.130 192.168.80.130:8301 alive server 1.3.1 2 djx-test <all>
192.168.80.129 192.168.80.129:8301 alive server 1.3.1 2 djx-test <all>
192.168.80.128 192.168.80.128:8301 alive server 1.3.1 2 djx-test <all>
