监控介绍和安装zabbix4.0

监控介绍

为何要作监控？

能够提早发现潜在的故障隐患，第一时间解决掉。把影响下降。

常见的监控软件：

cacti nagios zaabix（用得最多） open-falcon prometheus grafana 等等

安装zabbix4.0

[root@wangzb01 ~]#  rpm -ivh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

获取https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

[root@wangzb01 ~]# yum list | grep zabbix  //查看zabbix相关的包
[root@wangzb01 ~]# yum install -y zabbix-agent zabbix-get zabbix-server-mysql zabbix-web zabbix-web-mysql   //安装这几个包
[root@wangzb01 ~]# netstat -ltnp  //查看端口，端口不要和nginx，Tomcat冲突

[root@wangzb01 ~]# mysql -uroot -pmysql   //登陆数据库
MariaDB [(none)]> create database zabbix   //建立数据库
MariaDB [(none)]> grant all on zabbix.* to 'zabbix'@'127.0.0.1' identified by 'zabbix';    //建立数据库用户名密码

[root@wangzb01 ~]# vi /etc/zabbix/zabbix_server.conf //编辑配置文件

DBHost=127.0.0.1
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

[root@wangzb01 ~]# systemctl start zabbix-server  //启动服务
[root@wangzb01 ~]# ps aux | grep zabbix  //查看服务

发现并未启动成功
[root@wangzb01 ~]# vim /var/log/zabbix/zabbix_server.log //查看日志

缘由是没有导入zabbix的数据库

[root@wangzb01 ~]# ls /usr/share/doc/zabbix-server-mysql-4.0.5/create.sql.gz    //查看create.sql文件

[root@wangzb01 ~]# mysql -uroot -pmysql zabbix < /usr/share/doc/zabbix-server-mysql-4.0.5/create.sql   //将create.sql导入到zabbix库中
[root@wangzb01 ~]# systemctl start zabbix-server  //再次启动服务
[root@wangzb01 ~]# ps aux | grep zabbix_server

因为nginx的80端口和zabbix须要的httpd服务的80端口冲突，所以须要停用nginx服务并启用httpd服务

[root@wangzb01 ~]# systemctl stop nginx
[root@wangzb01 ~]# systemctl start httpd
[root@wangzb01 ~]# netstat -lntp

tcp6       0      0 :::80                   :::*                    LISTEN      8554/httpd
能够看到80端口对应的服务是httpd

在浏览器中输入地址加80端口便可打开zabbix

而后在浏览器输入地址http://192.168.1.34/zabbix 访问进入安装界面

有fail，须要定义时区

[root@wangzb01 ~]# vim /etc/php.ini

date.timezone = Aisa/Shanghai

[root@wangzb01 ~]# systemctl restart httpd

返回浏览器界面刷新一下，就所有OK了

点击下一步

输入server信息点击下一步

进入zabbix界面，到此，zabbix服务端安装完成。
