ip划分
| 主机名 | IP | 服务 |
|---|---|---|
| open-faclon-server | 192.168.150.200 | open-faclon-server |
| nginx-master | 192.168.150.199 | nginx、open-falcon-agent |
| nginx-backup | 192.168.150.198 | nginx、open-falcon-agent |
一、主机准备
操作系统
cat /etc/redhat-release
CentOS Stream release 8
ip规划
| 主机名 | IP | 服务 | |
|---|---|---|---|
| nginx_master | Nginx、open-falcon-agent | ||
| nginx_node | Nginx、open-falcon-agent、 | ||
| tomcat_node1 | Tomcat、open-falcon-agent、Redis | ||
| tomcat_node2 | Tomcat、open-falcon-agent、MySQL | ||
| openfalcon | 192.168.150.200 | open-falcon-server | |
二、环境配置
2.1修改主机名、修改hosts文件
修改主机名
hostnamectl set-hostname openfalcon
刷新环境，就可以看到修改后的主机名了
su -
追加重定向写入hosts文件中
echo "192.168.150.200 openfalcon" >> /etc/hosts
2.2配置阿里源，安装工具
安装基本工具
yum install -y wget yum-utils vim git net-tools lrzsz chrony unzip
配置阿里源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache && yum clean all
yum makecache用于创建或刷新 Yum 软件包管理器的元数据缓存
yum clean all用于清理 Yum 软件包管理器的缓存和临时文件。
2.3关闭防火墙、selinux
# 关闭防火墙
systemctl stop firewalld
# 开机启动关闭
systemctl disable firewalld
# 临时关闭Selinux
setenforce 0
# 永久关闭
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
可以看到config文件已经修改好了。
2.4配置时间
虚拟机上查看时间，与实际时间可能不对，需要调整，后面进行时间同步，同样需要确保时间是一样的。
修改timedatectl中的时区，改为shanghai
timedatectl set-timezone Asia/Shanghai
开启ntp service，修/etc/chrony.conf，添加**“pool cn.pool.ntp.org iburst”**
vim /etc/chrony.conf
使用中国的 NTP 服务器地址：
重新启动 chronyd 服务：
sudo systemctl restart chronyd
检查 chronyd 状态以确保服务正在运行：
sudo systemctl status chronyd
检查ntp是否开启
可以看到服务已经是活跃状态了。
2.5安装go
# 安装go语言开发包
yum install -y golang
#查看版本
[root@openfalcon opt]# go version
go version go1.20.6 linux/amd64
#查看go安装路径
[root@openfalcon opt]# find / -name go
/usr/bin/go
/usr/lib/golang/src/cmd/go #需要这个路径
/usr/lib/golang/src/cmd/vendor/golang.org/x/tools/go
/usr/lib/golang/src/go
/usr/lib/golang/bin/go
2.6安装redis
#安装 redis
yum install redis -y
启动redis，运行在后端
redis-server &
看后台有哪些任务
jobs #看后台作业有哪些
fg %1 #将后台作业切换到前台
bg %1 #从后台运行的作业继续在后台运行

初始化MySQL表结构
cd /tmp/ && git clone https://github.com/open-falcon/falcon-plus.git
cd /tmp/falcon-plus/scripts/mysql/db_schema/
