Influx-proxy 版本安装
服务器1:Circle 1 、influx-proxy
服务器2:Circle 2
# 下载influx-proxy(服务器1)
cd /opt
git clone https://github.com/chengshiwen/influx-proxy.git
# 安装go环境(服务器1)
tar -zxvf go1.15.linux-amd64.tar.gz -C /usr/local
echo "export PATH=\$PATH:/usr/local/go/bin" >> /etc/profile
echo "export GOPROXY=https://goproxy.io" >> /etc/profile
source /etc/profile
# 编译influx-proxy(服务器1)
cd influx-proxy
make
cp /opt/influx-proxy/bin/influx-proxy /usr/local/bin/
# 配置influx-proxy(服务器1)
vim /opt/influx-proxy/proxy.json
vim /etc/systemd/system/influx-proxy.service
# 安装influxdb(多实例)(服务器1)(服务器2)
wget https://dl.influxdata.com/influxdb/releases/influxdb-1.8.2.x86_64.rpm

chown influxdb:influxdb /mnt/data/influx-pr
# 启动influxDB、influx-proxy(服务器1)(服务器2)
systemctl start influxd-cluster@1
systemctl start influxd-cluster@2
systemctl start influx-proxy
# 设置用户、密码(两台服务器4个实例都需要设置)(服务器1)(服务器2)
influx -port 8086
create user 'username' with password 'password' with all privileges
exit
influx -port 8087

2.使用
基本命令
# 启动集群(三种都可以)
① influx-proxy -config /opt/influx-proxy/proxy.json
② systemctl start influx-proxy
③ nohup influx-proxy -config /opt/influx-proxy/proxy.json > /dev/null 2>&1 &
# 查看版本
influx-proxy -version
# 查看集群状态
curl http://127.0.0.1:7076/health -u root:123456
