CentOS 8 Stream上安装部署Zabbix 6.4，一气呵成完美版

在CentOS 8 Stream上安装Zabbix 6.4

**************************

centos 安装过程略

**********************************

关闭防火墙和selinux

sudo nano /etc/selinux/config

SELINUX=disabled

sudo systemctl stop firewalld

sudo systemctl disable firewalld

1. 安装Apache Web服务器

sudo dnf install httpd

sudo systemctl start httpd

sudo systemctl enable httpd

************************************************************************************

如果yum报错，更新一下源。使用vault.centos.org代替mirror.centos.org。没有忽略。

sudo sed -i -e "s|mirrorlist=|#mirrorlist=|g" /etc/yum.repos.d/CentOS-*

sudo sed -i -e "s|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g" /etc/yum.repos.d/CentOS-*

************************************************************************************

2. 安装MySQL

官网说MySQL 要求8.0系列都行 ，默认的yum是2 ，而默认的Maria 是10 都不符合 ，实际不行，安完后服务端是起不来的，日志提示sql版本3以上才行

这里的是3.0

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-community-server-8.3.0-1.el8.x86_64.rpm

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-community-common-8.3.0-1.el8.x86_64.rpm

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-community-client-plugins-8.3.0-1.el8.x86_64.rpm

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-community-libs-8.3.0-1.el8.x86_64.rpm

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-community-client-8.3.0-1.el8.x86_64.rpm

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-community-icu-data-files-8.3.0-1.el8.x86_64.rpm

rpm -ivh mysql-community-icu-data-files-8.3.0-1.el8.x86_64.rpm mysql-community-server-8.3.0-1.el8.x86_64.rpm mysql-community-common-8.3.0-1.el8.x86_64.rpm mysql-community-client-plugins-8.3.0-1.el8.x86_64.rpm mysql-community-libs-8.3.0-1.el8.x86_64.rpm mysql-community-client-8.3.0-1.el8.x86_64.rpm

这里注意 可能有依赖包，少哪个 装哪个 在下面网址上找到链接，替换包名字 ，重复上面两步即可

https://downloads.mysql.com/archives/community/

yum install mysql-server

systemctl enable mysqld.service #设置开机启动

systemctl start mysqld.service #启动服务

#mysql在安装后会创建一个root@locahost账户，并且把初始的密码放到了/var/log/mysqld.log文件中

[root@zabbix ~]# cat /var/log/mysqld.log | grep password

#使用初始密码登录

mysql -uroot -p

#修改mysql root密码

mysql > alter user 'root'@'localhost' identified with mysql_native_password BY '修改成你的密码';

mysql > flush privileges;

3. 安装PHP及相关扩展

sudo dnf install php php-mysqlnd php-json php-gd php-mbstring

优化，修改sudo nano /etc/php.ini的配置 post_max_size为16M、max_execution_time为300、max_input_time为300

环境搭建完成，下面按官方步骤不会报错，一气呵成

******************************************************************

a. Install Zabbix repository

产品手册

# rpm -Uvh https://repo.zabbix.com/zabbix/6.4/rhel/8/x86_64/zabbix-release-6.4-1.el8.noarch.rpm

# dnf clean all

b. Switch DNF module version for PHP

# dnf module switch-to php:7.4

c. 安装Zabbix server，Web前端，agent

# dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent

d. 创建初始数据库

产品手册

Make sure you have database server up and running.

在数据库主机上运行以下代码。

# mysql -uroot -p

password

mysql> create database zabbix character set utf8mb4 collate utf8mb4_bin;

mysql> create user zabbix@localhost identified by '修改成你的密码';

mysql> grant all privileges on zabbix.* to zabbix@localhost;

mysql> set global log_bin_trust_function_creators = 1;

mysql> quit;

导入初始架构和数据，系统将提示您输入新创建的密码。

# zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix

Disable log_bin_trust_function_creators option after importing database schema.

# mysql -uroot -p

password

mysql> set global log_bin_trust_function_creators = 0;

mysql> quit;

e. 为Zabbix server配置数据库

编辑配置文件 /etc/zabbix/zabbix_server.conf

DBPassword=password

f. 启动Zabbix server和agent进程

启动Zabbix server和agent进程，并为它们设置开机自启：

# systemctl restart zabbix-server zabbix-agent httpd php-fpm

# systemctl enable zabbix-server zabbix-agent httpd php-fpm

g. Open Zabbix UI web page

The default URL for Zabbix UI when using Apache web server is http://host/zabbix

注：sudo nano /etc/zabbix/zabbix_server.conf ,要修改 option:cachesize 下的 CacheSize=64 或更大，不然会报错

More than 75% used in the configuration cache， 可用的配置缓存超过75%。server down掉

zabbix监控端界面时间与服务器时间不对应问题，sudo nano /etc/php.ini ，date.timezone=Asia/Shanghai 取消注释并添加时区
