性能测试监控平台搭建-prometheus（二）

2. 安装prometheus

2.1 下载prometheus的tar包（合理上网）

官网下载地址：https://prometheus.io/download/

选择TLS的稳定版本下载

2.2 安装prometheus

创建存放安装包的目录

[root@master ~]# mkdir -p /opt/tgz

创建安装目录

[root@master ~]# mkdir -p /opt/app

prometheus的tar包上传到tgz目录下

[root@master ~]# cd /opt/tgz/
[root@master tgz]# ll

解压prometheus-2.53.2.linux-amd64.tar.gz

[root@master tgz]# tar zxvf prometheus-2.53.2.linux-amd64.tar.gz

将解压后端文件移动到/opt/app的目录下,并且修改目录下所以文件的权限给当前用户，我这里是root用户

[root@master tgz]# mv prometheus-2.53.2.linux-amd64 /opt/app/prometheus-2.53.2
[root@master tgz]# cd /opt/app
[root@master app]# chown -R root:root prometheus-2.53.2

创建prometheus的系统启动文件

[root@master ~]# vim /usr/lib/systemd/system/prometheus.service

在prometheus.service文件中输入如下内容，这里需要注意路径为本地的prometheus的目录位置

启动prometheus的服务

# 更新系统服务的daemon
[root@master ~]# systemctl daemon-reload
# 启动服务
[root@master ~]# systemctl start prometheus
# 设置服务为开机自动启动
[root@master ~]# systemctl enable prometheus
# 检查服务的启动状态
[root@master ~]# systemctl status prometheus
