手把手教你在centos8操作系统上部署zabbix6.0

实验环境

[itlaoxin@localhost ~]$ cat /etc/redhat-release 
CentOS Stream release 8
[itlaoxin@localhost ~]$ uname -r
4.18.0-365.el8.x86_64
[itlaoxin@localhost ~]$ free -m
              total        used        free      shared  buff/cache   available
Mem:           3704        1110        1434          21        1159        2334
Swap:          2047           0        2047
[itlaoxin@localhost ~]$ 

[itlaoxin@localhost ~]$ cat /proc/cpuinfo |grep "cpu cores"
cpu cores	: 2
cpu cores	: 2

可以看到，当前所用的系统是 centos-stream 8 , CPU是2核的，内存是 4G

部署底层环境LAMP

注意： zabbix 6.0 需要安装10.6.5以上的Mariadb，而系统自带的为10.5，所以需要安装额外源

cat <<EOF > /etc/yum.repos.d/mariadb.repo
# MariaDB 10.6 CentOS repository list - created 2022-01-16 15:10 UTC
# https://mariadb.org/download/
[mariadb]
name = MariaDB
baseurl = https://mirrors.cloud.tencent.com/mariadb/yum/10.6/centos8-amd64
module_hotfixes=1
gpgkey=https://mirrors.cloud.tencent.com/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1
EOF

开始安装底层环境

[root@localhost itlaoxin]# dnf install mariadb mariadb-server httpd httpd-tools php php-cli php-json php-gd php-mbstring php-pdo php-xml php-mysqlnd php-pecl-zip wget -y

配置zabbix源

[itlaoxin@localhost ~]$ sudo su


[sudo] itlaoxin 的密码：
[root@localhost itlaoxin]# 
[root@localhost itlaoxin]# rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-1.el8.noarch.rpm
获取https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-1.el8.noarch.rpm

安装zabbix

dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent2 -y

配置MySQL

root@localhost itlaoxin]# systemctl start mariadb && systemctl enable mariadb
Created symlink /etc/systemd/system/multi-user.target.wants/mariadb.service → /usr/lib/systemd/system/mariadb.service.

[root@localhost itlaoxin]# mysql

MariaDB [(none)]>

设置数据库名： zabbix
用户名：zabbix
密码： 123456

让用户zabbix，能够通过本地访问数据库zabbix，使用123456作为密码

MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.001 sec)

MariaDB [(none)]> grant all on zabbix.* to zabbix@'localhost' identified by '123456';
Query OK, 0 rows affected (0.001 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.001 sec)

MariaDB [(none)]> quit
Bye

导入初始架构和数据

[root@localhost zabbix-server-mysql]# zcat /usr/share/doc/zabbix-sql-scripts/mysql/server.sql.gz | mysql -uzabbix -p zabbix

为zabbix server配置数据库

[root@itlaoxin ~]# vim /etc/zabbix/zabbix_server.conf 
124 DBPassword=123456

[root@localhost zabbix-server-mysql]# grep DBPassword /etc/zabbix/zabbix_server.conf |grep -v ^#
DBPassword=123456

启动Zabbix server和agent进程

systemctl restart zabbix-server zabbix-agent2 httpd php-fpm
systemctl enable zabbix-server zabbix-agent2 httpd php-fpm

前端配置

关闭防火墙和selinux

root@localhost zabbix-server-mysql]# setenforce 0
[root@localhost zabbix-server-mysql]# systemctl stop firewalld.service 
[root@localhost zabbix-server-mysql]#
