zabbix介绍

zabbix主要有zabbix-server及zabbix-agent组成，zabbix-server是服务端，需要配置数据库；zabbix-agent相当于客户端，需要监控的服务器必须安装zabbix-agent，zabbix-server和zabbix-agent可以共存于同一台服务器。

安装服务器

-i 交互模式
-d 后端运行
-h 容器的hostname
--name 容器名称
--network 指定网卡
--ip 指定IP
-p 端口映射
-v /sys/fs/cgroup:/sys/fs/cgroup 解决mysql服务启动暂停的问题
--privileged=true与/usr/sbin/init 特权模式

[root@localhost ~]# docker run -i -d -h zabbix --name zabbix --network docker-br0 --ip 172.127.0.101 -p 3306:3306 -p 8080:80 --privileged=true -v /sys/fs/cgroup:/sys/fs/cgroup centos:7 /usr/sbin/init

[root@localhost ~]# docker exec -it zabbix /bin/bash
[root@zabbix /]# yum -y update
[root@zabbix /]# yum -y install vim zip unzip net-tools wget


[root@zabbix /]# mkdir Tools
[root@zabbix /]# cd Tools
[root@zabbix Tools]# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
[root@zabbix Tools]# yum clean all

[root@zabbix Tools]# yum -y install zabbix-server-mysql

[root@zabbix Tools]# yum -y install centos-release-scl

[root@zabbix Tools]# vim /etc/yum.repos.d/zabbix.repo

[zabbix-frontend]
...
enabled=1
...


[root@zabbix Tools]# yum -y install zabbix-web-mysql-scl zabbix-apache-conf-scl

8.1 下载mysql yum源

执行完rpm -ivh mysql57-community-release-el7-9.noarch.rpm会在/etc/yum.repos.d/下生成两个文件

[root@zabbix Tools]# wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
[root@zabbix Tools]# rpm -ivh mysql57-community-release-el7-9.noarch.rpm
[root@zabbix Tools]# ll /etc/yum.repos.d/

8.2 更改yum源为国内镜像（官网实在是慢，安装过的老铁都知道）

mysql版本为5.7

[root@zabbix Tools]# cd /etc/yum.repos.d
[root@zabbix yum.repos.d]# mv mysql-community.repo mysql-community.repo.bak
[root@zabbix yum.repos.d]# vim mysql-community.repo
[root@zabbix yum.repos.d]# cat mysql-community.repo

8.3 导入mysql的key

[root@zabbix yum.repos.d]# rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022

8.4 安装

需在/etc/yum.repos.d路径下

[root@zabbix yum.repos.d]# yum -y install mysql-server

8.5 mysql服务管理

[root@zabbix yum.repos.d]# systemctl start mysqld   # 启动服务
[root@zabbix yum.repos.d]# systemctl restart mysqld # 重启服务
[root@zabbix yum.repos.d]# systemctl stop mysqld    # 停止服务
[root@zabbix yum.repos.d]# systemctl status mysqld  # 查看状态

8.6 获取mysql第一次登录密码

[root@zabbix yum.repos.d]# grep 'temporary password' /var/log/mysqld.log

8.7 登录mysql

[root@zabbix yum.repos.d]# mysql -uroot -p'kLop*uggJ0L6'

8.8 修改密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Yangxiao214.';

8.9 开启远程控制

user表中host的值为 % 代表任意的客户端,可替换成具体IP地址。

mysql> show databases;
mysql> use mysql
mysql> show tables
mysql> desc user;
mysql> select host,user from user;
mysql> update user set host='%' where user='root';
mysql> flush privileges;

mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by 'Yangxiao214.';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> quit

[root@zabbix yum.repos.d]# cd /Tools/
[root@zabbix Tools]# wget https://cdn.zabbix.com/zabbix/sources/stable/5.0/zabbix-5.0.21.tar.gz
[root@zabbix Tools]# ll
[root@zabbix Tools]# tar -zxvf zabbix-5.0.21.tar.gz
[root@zabbix Tools]# cd zabbix-5.0.21/database/mysql/

[root@zabbix mysql]# mysql -uzabbix -p'Yangxiao214.'
mysql> use zabbix
mysql> source /Tools/zabbix-5.0.21/database/mysql/schema.sql;
mysql> source /Tools/zabbix-5.0.21/database/mysql/images.sql;
mysql> source /Tools/zabbix-5.0.21/database/mysql/data.sql;
mysql> quit;

/set nu 显示行号
/set nu! 取消显示行号

[root@zabbix mysql]# vim /etc/zabbix/zabbix_server.conf
[root@zabbix mysql]# grep ^DB /etc/zabbix/zabbix_server.conf

DBHost=localhost // 91行
DBName=zabbix // 100行
DBUser=zabbix // 116行
DBPassword=Yangxiao214. // 124行

[root@zabbix mysql]# vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf

[root@zabbix mysql]# systemctl start zabbix-server httpd rh-php72-php-fpm      # 启动
[root@zabbix mysql]# systemctl restart zabbix-server httpd rh-php72-php-fpm    # 重启
[root@zabbix mysql]# systemctl stop zabbix-server httpd rh-php72-php-fpm       # 停止
[root@zabbix mysql]# systemctl status zabbix-server httpd rh-php72-php-fpm     # 查看
[root@zabbix mysql]# systemctl enable zabbix-server  httpd rh-php72-php-fpm    # 开机自启

安装zabbix agent

[root@zabbix mysql]# cd Tools
[root@zabbix Tools]# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
[root@zabbix Tools]# yum clean all
[root@zabbix Tools]# cd zabbix-5.0.21/database/mysql
[root@zabbix mysql]# yum -y install zabbix-agent


[root@zabbix mysql]# vim /etc/zabbix/zabbix_agentd.conf


DenyKey=system.run[*]      // 85 行
Server=172.127.0.101       // 117 行，zabbix-server 的ip
ServerActive=172.127.0.101 // 158 行，zabbix-server 的ip
Hostname=zabbix            // 169 行，zabbix-agent的hostname


[root@zabbix mysql]# systemctl start zabbix-agent    # 启动
[root@zabbix mysql]# systemctl restart zabbix-agent  # 重启
[root@zabbix mysql]# systemctl stop zabbix-agent     # 停止
[root@zabbix mysql]# systemctl status zabbix-agent   # 查看
[root@zabbix mysql]# systemctl enable zabbix-agent   # 开机自启
