携手创作，共同成长！这是我参与「掘金日新计划 · 8 月更文挑战」的第2天，点击查看活动详情

1.zabbix4.0监控系统部署

zabbix4.0软件分为：zabbix-server-mysql zabbix-web-mysql

这里虽然是-mysql但是不是安装的数据库哟，而是这个zabbix将来使用什么版本的数据库，可以是postgresql也可以是mysql

预先配置

[root@zabbix-server ~]# setenforce 0
[root@zabbix-server ~]# sed -ri '/^SELINUX=/c SELINUX=disabled' /etc/sysconfig/selinux 
[root@zabbix-server ~]# sed -ri '/^SELINUX=/c SELINUX=disabled' /etc/selinux/config 
[root@zabbix-server ~]# systemctl stop firewalld
[root@zabbix-server ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

1.1.zabbix4.0安装

1.获取zabbix4.0镜像源
[root@zabbix-server ~]# wget http://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

2.安装镜像源
[root@zabbix-server ~]# rpm -ivh zabbix-release-4.0-1.el7.noarch.rpm 
安装完成后/etc/yum.repos.d/会多出来镜像文件
[root@zabbix-server ~]# ls /etc/yum.repos.d/
zabbix.repo

3.修改镜像文件base地址为清华园
[root@zabbix-server ~]# vim /etc/yum.repos.d/zabbix.repo 
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=http://mirror.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=http://mirror.tuna.tsinghua.edu.cn/zabbix/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1

4.开启yum缓存方便以后复用
[root@zabbix-server ~]# vim /etc/yum.conf 
keepcache=1

5.安装zabbix4.0软件
[root@zabbix-server ~]# yum -y install zabbix-server-mysql zabbix-web-mysql --downloaddir=/root

1.2.zabbix数据库配置

1.安装mysql
[root@zabbix-server ~]# yum -y install mariadb-server

2.启动数据库
[root@zabbix-server ~]# systemctl start mariadb.service 
[root@zabbix-server ~]# systemctl enable mariadb.service

3.mysql安全配置，回车、n、一路y
[root@zabbix-server ~]# mysql_secure_installation 
Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Set root password? [Y/n] n
 ... skipping.

Remove anonymous users? [Y/n] y
 ... Success!

Disallow root login remotely? [Y/n] y
 ... Success!

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reload privilege tables now? [Y/n] y
 ... Success!

4.创建数据库并授权
[root@zabbix-server ~]# mysql
MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;
MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@'%' identified by '123456';

授权root用户远程登录并使用Navicat去查看数据库
MariaDB [(none)]>  grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;

5.导入zabbix SQL
[root@zabbix-server ~]# zcat /usr/share/doc/zabbix-server-mysql-4.0.24/create.sql.gz | mysql -uroot -p123456 zabbix

扩展：zcat可以看到压缩包中的文件内容，但是必须压缩包中只有一个文件

使用Navicat查看导入的sql

在这里插入图片描述

1.3.配置zabbix server

1.修改zabbix server配置文件
[root@zabbix-server ~]# vim /etc/zabbix/zabbix_server.conf 
DBHost=192.168.81.210
DBName=zabbix
DBUser=zabbix
DBPassword=123456

整个配置文件内容
[root@zabbix-server ~]# cat /etc/zabbix/zabbix_server.conf | egrep -v '^$|^#'
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=0
PidFile=/var/run/zabbix/zabbix_server.pid
SocketDir=/var/run/zabbix
DBHost=192.168.81.210
DBName=zabbix
DBUser=zabbix
DBPassword=123456
SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
Timeout=4
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
LogSlowQueries=3000

2.启动zabbix-server
[root@zabbix-server ~]# systemctl start zabbix-server.service 
[root@zabbix-server ~]# systemctl enable zabbix-server.service

1.4.配置zabbix web

1.设置时区
[root@zabbix-server ~]# vim /etc/httpd/conf.d/zabbix.conf 
	<IfModule mod_php5.c>
        php_value max_execution_time 300
        php_value memory_limit 128M
        php_value post_max_size 16M
        php_value upload_max_filesize 2M
        php_value max_input_time 300
        php_value max_input_vars 10000
        php_value always_populate_raw_post_data -1
        php_value date.timezone Asia/Shanghai
    </IfModule>

2.重启httpd
[root@zabbix-server ~]# systemctl start httpd 
[root@zabbix-server ~]# systemctl enable httpd
