我这次的安装环境：
zabbix：5.0 LTS版；
操作系统：centos 7；
数据库：mysql 5.7（建议不要用版本8，会碰到很多故障，比如加密方式等，我们就存储个监控数据，不需要那么新，用5.7版即可，而且这个版本也是比较推荐的版本）。
整体安装流程，其实也就2步：
1、安装mysql数据库：
2、安装zabbix：根据下面这个链接选择自己的系统版本，然后会生成对应的操作步骤，根据说明操作即可。
https://www.zabbix.com/cn/download?zabbix=5.0&os_distribution=centos&os_version=7&db=mysql&ws=apache
详细步骤：
写在前面：最好把centos的selinux和Firewall关掉，能避免很多问题。如果你觉得不安全，可以这样安装成功后，再打开他们，并设置想要的放行规则即可。
systemctl status firewalld.service #查询防火墙当前状态
systemctl stop firewalld.service #临时禁用防火墙，下次重启系统会恢复
systemctl disable firewalld.service #永久禁用防火墙
[root@localhost ~]# getenforce #查询当前selinux状态。
Enforcing
[root@localhost ~]# setenforce 0 #临时关闭selinux。
[root@localhost ~]#
[root@localhost ~]# getenforce
Permissive
永久关闭selinux需要修改配置文件：/etc/selinux/config
[root@localhost ~]# vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=enforcing 修改为"SELINUX=disabled"
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

1、安装mysql：官网：https://downloads.mysql.com/archives/community/。
(按下面的命令顺序操作，或者参考这篇文章：https://blog.csdn.net/Tiger_Paul/article/details/123044609
[root@localhost~]wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.37-1.el7.x86_64.rpm-bundle.tar
[root@localhost~]# rpm -aq | grep mariadb
mariadb-libs-5.5.68-1.el7.x86_64
[root@localhost~]# rpm -e mariadb-libs-5.5.68-1.el7.x86_64 --nodeps
[root@localhost~]# tar -xvf mysql-5.7.37-1.el7.x86_64.rpm-bundle.tar -C /tmp
[root@localhost tmp]# cd /tmp/
建议按顺序安装：common --> libs --> clients --> server
[root@localhost tmp]# rpm -ivh mysql-community-libs-compat-5.7.37-1.el7.x86_64.rpm
#一个都不能少，不然后面会出问题。这个如果不装，在执行zabbix教程中的：zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix整条命令时，会报错：no such file or directory。此时，只需要补充安装这个包即可。
[root@localhost tmp]# rpm -ivh mysql-community-common-5.7.37-1.el7.x86_64.rpm
[root@localhost tmp]# rpm -ivh mysql-community-libs-5.7.37-1.el7.x86_64.rpm
[root@localhost tmp]# rpm -ivh mysql-community-client-5.7.37-1.el7.x86_64.rpm
[root@localhost tmp]# rpm -ivh mysql-community-server-5.7.37-1.el7.x86_64.rpm
2、查看mysql是否安装好了
[root@localhost ~]# which mysql #看下mysql安装到哪里了？
/usr/bin/mysql
[root@localhost ~]# systemctl start mysqld #启动mysql服务
[root@localhost ~]# systemctl status mysqld #查看mysql运行状态

[root@localhost ~]#
mysql数据库安装到此完成，下面就开始安装zabbix。
安装zabbix比较简单，按照下面这个官方文档复制粘贴命令即可：
https://www.zabbix.com/cn/download?zabbix=5.0&os_distribution=centos&os_version=7&db=mysql&ws=apache
如果你严格按照我上面说的做，在安装zabbix的时候是不会出任何问题的。好，到此zabbix就安装好了，下面就可以用ip登录zabbix了！
如果出现时区问题，可以重新修改timezone，把前面的那个分号去掉。然后在重启下相关服务：
[root@localhost ~]# systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm
做好步骤g后，就可以了，然后根据这个：https://www.zabbix.com/documentation/5.0/zh/manual/quickstart/login，登录zabbix。初始管理员为：Admin，密码：zabbix。
