Influx-proxy 版本安裝
服務器1:Circle 1 、influx-proxy
服務器2:Circle 2
# 下載influx-proxy(服務器1) cd /opt git clone https://github.com/chengshiwen/influx-proxy.git
# 安裝go環境(服務器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
# 編譯influx-proxy(服務器1) cd influx-proxy make cp /opt/influx-proxy/bin/influx-proxy /usr/local/bin/
# 配置influx-proxy(服務器1) vim /opt/influx-proxy/proxy.json vim /etc/systemd/system/influx-proxy.service
# 安裝influxdb(多實例)(服務器1)(服務器2) wget https://dl.influxdata.com/influxdb/releases/influxdb-1.8.2.x86_64.rpm yum -y localinstall influxdb-1.8.2.x86_64.rpm vim /etc/influxdb/influxdb.conf.1 vim /etc/influxdb/influxdb.conf.2 vim /etc/systemd/system/influxd-cluster@.service

# 啟動influxDB、influx-proxy(服務器1)(服務器2) systemctl start influxd-cluster@1 systemctl start influxd-cluster@2 systemctl start influx-proxy
# 設置用戶、密碼(兩台服務器4個實例都需要設置)(服務器1)(服務器2) influx -port 8086 create user 'username' with password 'password' with all privileges exit influx -port 8087 create user 'username' with password 'password' with all privileges exit
2.使用
基本命令
# 啟動集群(三種都可以) 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
# 查看集群狀態 curl http://127.0.0.1:7076/health -u root:123456
