zabbix自动发现

在一台机器(例10.3.145.65) 部署zabbix-server，实现监控。 其他机器均须部署 zabbix-agent (10.3.145.39、10.3.145.64、10.3.145.63)

安装zabbix-server

## 安装zabbix源(官方)(四台机子都进行配置)[root@10v3v145v65 roles]#rpm -ivh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm​## 而后更新我们的yum仓库：[root@10v3v145v65 roles]# yum repolist ​## 安装[root@10v3v145v65 ~]# yum -y install zabbix-agent zabbix-get zabbix-sender zabbix-server-mysql zabbix-web zabbix-web-mysql​​

## 1.创建 mariadb.repo[root@10v3v145v65 roles]# vim /etc/yum.repos.d/mariadb.repo[mariadb]name = MariaDB baseurl = https://mirrors.ustc.edu.cn/mariadb/yum/10.4/centos7-amd64 gpgkey=https://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB gpgcheck=12.下载安装[root@10v3v145v65 roles]# yum -y install MariaDB-server MariaDB-client3.首先，我们修改一下配置文件——/etc/my.cnf.d/server.cnf [root@10v3v145v65 roles]#vim /etc/my.cnf.d/server.cnf [mysqld]    skip_name_resolve = ON          #跳过主机名解析    innodb_file_per_table = ON      #    innodb_buffer_pool_size = 256M  #缓存池大小    max_connections = 2000          #最大连接数    log-bin = master-log            #开启二进制日志4.重启我们的数据库服务[root@10v3v145v65 roles]# systemctl restart mariadb[root@10v3v145v65 roles]# mysql_secure_installation#初始化mariadb5.登录数据库#mysqlMariaDB [(none)]> create database zabbix character set 'utf8';  # 创建zabbix数据库MariaDB [(none)]> grant all on zabbix.* to 'zbxuser'@'10.3.145.%' identified by 'keer';# 注意授权网段MariaDB [(none)]> flush privileges;           # 刷新授权6.导入表首先，我们来查看一下，`zabbix-server-mysql`这个包提供了什么/usr/share/doc/zabbix-server-mysql-4.0.9/create.sql.gz      #生成表的各种脚本 #gzip -d create.sql.gz #head  create.sql   #查看内容 vim /usr/share/doc/zabbix-server-mysql-4.0.9/create.sql  USER zabbix    #如果缺少，第一行添加 7.导入数据 cd /usr/share/doc/zabbix-server-mysql-4.0.9/[root@10v3v145v65 zabbix-server-mysql-4.0.9]# mysql -uzbxuser -h10.3.145.65 -p zabbix < create.sql 8.修改配置文件 cd /etc/zabbix/ cp zabbix_server.conf{,.bak}  #为了可以反悔，cp一份 vim zabbix_server.conf #修改后配置如下ListenPort=10051            #默认监听端口SourceIP=10.3.145.65       #发采样数据请求的IP(本机)DBHost=10.3.145.65         #数据库对外的主机DBName=zabbix               #数据库名称DBUser=zbxuser              #数据库用户DBPassword=keer             #数据库密码DBPort=3306                 #数据库启动端口9.开启服务#systemctl start zabbix-server.service#ss -nutl |grep 10051tcp    LISTEN     0      128       *:10051                 *:*                  tcp    LISTEN     0      128      :::10051                :::*    Alias /zabbix /usr/share/zabbix     #我们访问的时候要在主机后加上/zabbix来访问我们这个服务#vim /etc/php.ini      #配置时区    [Date]    ; Defines the default timezone used by the date functions    ; http://php.net/date.timezone    date.timezone = Asia/Shanghai   10.接下来，我们就可以启动我们的`httpd`服务了：[root@10v3v145v65 zabbix]# systemctl restart httpd.service ## 访问 10.3.145.65/zabbix## 进行初始化配置

ansible安装zabbix-agent
