zabbix-4.4

安装部署

#配置zabbix官方仓库
[root@zabbix ~]# rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm

#把官方源改为阿里云镜像源。 
#由于官方源是国外的镜像仓库，速度非常慢，改用阿里云的镜像仓库会非常快。只需在官方源的repo文件中修改URL即可。
[root@zabbix ~]# sed -i 's@http://repo.zabbix.com@https://mirrors.aliyun.com/zabbix@g' /etc/yum.repos.d/zabbix.repo

#安装
[root@zabbix ~]# yum install -y zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-nginx-conf

#安装配置数据库。 数据库使用mysql和mariadb都可以，这里以二进制安装mysql-5.6.42为例
[root@zabbix ~]# wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.6.42-linux-glibc2.12-x86_64.tar.gz
[root@zabbix ~]# tar xf mysql-5.6.42-linux-glibc2.12-x86_64.tar.gz

#报错：
启动zabbix-server,使用netstat -lntp没有zabbix-server：10051端口，
systemctl status zabbix-server状态正常，
tail -f /var/log/zabbix/zabbix_server.log查看日志报错
  9665:20210424:104103.455 database is down: reconnecting in 10 seconds

#解决：
find查找mysql.sock文件位置，做软链接
[root@zabbix ~]# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock


#监控页，字体乱码
在windows系统中，找到字体存放目录C:\Windows\Fonts，找一个自己喜欢的字体，我选择的是楷体
[root@zabbix ~]# cd /usr/share/zabbix
[root@zabbix /usr/share/zabbix]# ls
#查看有没有fonts目录，没有则创建
[root@zabbix /usr/share/zabbix]# mkdir fonts
#上传字体
[root@zabbix /usr/share/zabbix/fonts]# ls 
SIMKAI.TTF

#切换目录
[root@zabbix /usr/share/zabbix/fonts]# cd /etc/alternatives/
[root@zabbix /etc/alternatives]# ll

#删除原有的，做软链接
[root@zabbix /etc/alternatives]# rm -rf zabbix-web-font
[root@zabbix /etc/alternatives]# ln -s /usr/share/zabbix/fonts/SIMKAI.TTF /etc/alternatives/zabbix-web-font

[root@zabbix /etc/alternatives]# systemctl restart zabbix-server
