本次的下载地址是：https://repos.influxdata.com/rhel/7/x86_64/stable，安装文件为influxdb-1.7.6.x86_64.rpm。
2.安装并绑定端口
# 1.本地安装 yum localinstall -y influxdb-1.7.6.x86_64.rpm # 2.修改配置 vim /etc/influxdb/influxdb.conf # 以下三个文件夹可根据需要进行修改 [meta] dir = "/var/lib/influxdb/meta" [data] dir = "/var/lib/influxdb/data" wal-dir = "/var/lib/influxdb/wal" # http相关参数 [http] # 开启 HTTP API enabled = true # bind-address = ":8086" # 默认绑定端口为 8086可进行修改 bind-address = ":18088" # auth-enabled = false # 用户及密码验证默认关闭【注意】创建管理员用户后生产环境进行开启 auth-enabled = true
3.启动服务并创建管理员用户
首先启动 influxdb 服务端：
# 1.正常后台启动 [root@aliyun ~]# systemctl start influxd # 前台启动可以查看运行状态 也可以用 -config 指定启动时的配置文件 [root@aliyun ~]# /usr/bin/influxd 8888888 .d888 888 8888888b. 888888b. 888 d88P" 888 888 "Y88b 888 "88b 888 888 888 888 888 888 .88P 888 88888b. 888888 888 888 888 888 888 888 888 8888888K. 888 888 "88b 888 888 888 888 Y8bd8P' 888 888 888 "Y88b 888 888 888 888 888 888 888 X88K 888 888 888 888 888 888 888 888 888 Y88b 888 .d8""8b. 888 .d88P 888 d88P 8888888 888 888 888 888 "Y88888 888 888 8888888P" 8888888P"
进入命令行工具界面进行用户添加，由于修改了默认绑定的端口，需要添加-port参数指定端口：
# 2.进入命令行工具 [root@aliyun ~]# influx -port '18088' Connected to http://localhost:18088 version 1.7.6 InfluxDB shell version: 1.7.6 Enter an InfluxQL query # 创建管理员用户 > create user "admin" with password 'admin' with all privileges; # 查看用户信息 > show users; user admin ---- ----- admin true
4.开启用户密码认证
vim /etc/influxdb/influxdb.conf # 3.http相关参数 [http] # 用户及密码验证默认关闭【注意】创建管理员用户后生产环境进行开启 auth-enabled = true
重启服务后使用用户名及密码进行登录：
# 重启服务 systemctl restart influxd # 如果不使用用户及密码登录操作时会报错 [root@aliyun ~]# influx -port '18088' Connected to http://localhost:18088 version 1.7.6 InfluxDB shell version: 1.7.6 Enter an InfluxQL query > show users; ERR: unable to parse authentication credentials Warning: It is possible this error is due to not setting a database. Please set a database with the command "use <database>". # 验证用户及密码 > auth username: admin password: > show users; user admin ---- ----- admin true # 使用用户名及密码正确登录 [root@aliyun ~]# influx -port '18088' -username 'admin' -password 'admin' Connected to http://localhost:18088 version 1.7.6 InfluxDB shell version: 1.7.6 Enter an InfluxQL query > show users; user admin ---- ----- admin true
5.开机自启配置
# enable 不能用 提示层级太深 systemctl enable influxd Failed to execute operation: Too many levels of symbolic links
修改/etc/rc.loal文件实现开启启动：
vim /etc/rc.loal # 添加启动命令 systemctl start influxd
