    环境要求(执行下面红色代码即可查看本机信息):
    rpm -q centos-release
    centos-release-7-9.2009.0.el7.centos.x86_64
    uname -r
    3.10.0-1127.el7.x86_64
    zabbix官网:https://www.zabbix.com/

1.关闭防火墙

    如果是虚拟机直接关闭防火墙即可
    如果是线上的建议开启端口:
    https://blog.csdn.net/WeiHao0240/article/details/99674024

# 1:查看防火状态
systemctl status firewalld

# 2:暂时关闭防火墙
systemctl stop firewalld

# 3:永久关闭防火墙
systemctl disable firewalld

# 4:重启防火墙
systemctl enable firewalld

2. 安装Zabbix

# 1. 下载yum源
rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

# 2.yum清理缓存
yum clean all

# 3.安装server, agent, get, sender, web
yum -y install zabbix-server-mysql zabbix-agent zabbix-get zabbix-sender zabbix-web zabbix-web-mysql

# 4.启用红帽软件集合
yum-config-manager --enable rhel-server-rhscl-7-rpms

# 5.查看前端仓库是否支持
vim /etc/yum.repos.d/zabbix.repo
# 修改[zabbix-frontend] 下面 enabled=1

# 6.安装前端包 apache
yum install zabbix-web-mysql-scl zabbix-apache-conf-scl

 

    有可能会报错:
    Error: Package: zabbix-web-deps-scl-5.0.6-1.el7.noarch (zabbix-frontend)
    Requires: rh-php72-php-gd
    Error: Package: zabbix-web-deps-scl-5.0.6-1.el7.noarch (zabbix-frontend)

    说明没有安装rh-php

# 1. 卸载旧PHP
yum remove php* -y

# 2. 安装rh
yum install centos-release-scl-rh

# 3. 查询php
yum search php

# 4.安装
yum install rh-php73
scl enable rh-php73 bash

# 5.查看版本
php -v

# 然后再安装前端包
yum -y  install zabbix-web-mysql-scl zabbix-apache-conf-scl

3. 安装MySQL

    这里安装的MySQL5.7
    如果已经安装了请跳过这步
    安装连接:https://blog.csdn.net/WeiHao0240/article/details/99644197

4. 导入zabbix表

# 1.登录MySQL, 必须要用root用户
mysql -uroot -p
# 2.创建zabbix数据库
create database zabbix character set utf8 collate utf8_bin;
# 3.创建zabbix用户 并制定验证密码
create user zabbix@localhost identified by 'Zabbix2020..';
# 4.给zabbix用户赋予zabbix数据库权限
grant all privileges on zabbix.* to zabbix@localhost;
# 退出
quit;

# 导入数据库表
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

 

# 修改数据库配置
vim /etc/zabbix/zabbix_server.conf

# DBName 就是新建数据库的名称
# DBUser 就是新建的用户
#DBpassword 登录密码

# 设置php时区
vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
# 设置上海时区如下:
#  php_value[date.timezone] = Asia/Shanghai

5. 启动

systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm
systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm

 

    有可能会出错
    Job for zabbix-server.service failed because the control process exited with error code. See “systemctl status zabbix-server.service” and “journalctl -xe” for details.

# 查看详细错误信息
journalctl -xe

    缺少libmysqlclient.so.18
    zabbix_server: /lib64/libmysqlclient.so.18: no version information available (required by zabbix_server)
    zabbix_server: /lib64/libmysqlclient.so.18: version `libmysqlclient_18’ not found (required by zabbix_server)

说明zabbix_server需要libmysqlclient.so.18
但是本地没有, 我的本地是libmysqlclient.so.21 高版本不能用
缺少libmysqlclient.so.18解决

    提取码：widh

# 从上面的连接下载放到 /usr/lib/  下面
# 也拷贝到lib64下面
cp /usr/lib/libmysqlclient.so.18 /usr/lib64/

    继续报错:
    =error msg=“agent: session failed” backoff=8s error="rpc error: code = Unavailable desc = all SubConns are in Transien

SELinux 解决

    Enforcing：强制模式。代表SELinux在运行中，且已经开始限制domain/type之间的验证关系
    Permissive：宽容模式。代表SELinux在运行中，不过不会限制domain/type之间的验证关系，即使验证不正确，进程仍可以对文件进行操作。不过如果验证不正确会发出警告
    Disabled：关闭模式。SELinux并没有实际运行

getenforce
setenforce 0
getenforce

在这里插入图片描述
MySQL8.0解决

    Operation CREATE USER failed for ‘zabbix’@’%’
    You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'identified by
    密码验证必须都要用with mysql_native_password by

# 查看用户
select host,user from user;
# 删除
delete from mysql.user where user = 'zabbix';
# 这一步也要执行
drop user zabbix@localhost;
# 刷新权限
flush privileges;
# 创建用户
create user 'zabbix'@'localhost' IDENTIFIED  with mysql_native_password by 'Zabbix2020..';
# 修改为%
update user set host = '%' where user = 'zabbix';
# 刷新权限
flush privileges;

ALTER user 'zabbix'@'%' IDENTIFIED  with mysql_native_password by 'Zabbix2020..';

flush privileges;

6. 验证

ps -ef | grep zabbix

7.web页面

下面换成你的ip即可
