Installation preparation:
Zabbix updated to the latest version 6.4, the following is the installation process of Zabbix6.4 on CentOS7 system
Zabbix does not support the quick installation of the server side on the CentOS7 system according to official documents since version 6.0
So we can only compile and install step by step.
Zabbix source package address: https://www.zabbix.com/cn/download_sources
Zabbix6.4 official document address
https://www.zabbix.com/documentation/6.4/en/manual/installation/getting_zabbix
Installation process:
Turn off firewalls and security mechanisms
# close the firewall
systemctl stop firewalld.service
# close the security mechanism
setenforce 0

start mysql
# start MySQL
systemctl start mysqld
#MySQLJoin and start self-starting
systemctl enable mysqld
View MySQL service status
#The following three methods are acceptable (it is recommended to read them all)
systemctl status mysqld.service
netstat -anptu |grep mysql
ps -ef |grep mysql
After MySQL starts, it will initialize and generate a MySQL password
cat /var/log/mysqld.log | grep password

Install Zabbix6.4
Download the source package and unzip it
#Download the official source package
wget https://cdn.zabbix.com/zabbix/sources/stable/6.4/zabbix-6.4.0.tar.gz
#Create zabbix directory
mkdir /usr/local/zabbix
# unzip
tar -zxvf zabbix-6.0.1.tar.gz -C /usr/local/zabbix/
Create Zabbix users and user groups
(1) For all Zabbix daemons, an unprivileged user is required, if the Zabbix daemon is started from an unprivileged user account, it will run as this user.
(2) However, if a daemon is started as "root", it switches to the "zabbix" user, which must exist. In the Linux system, you can use the following command to create a user (the user belongs to its own user group, "zabbix")
#Create zabbix group
groupadd zabbix
#Create zabbix user
useradd -g zabbix -M -s /sbin/nologin zabbix
Compile and install Zabbix6.4
#Move to the zabbix directory
cd /usr/local/zabbix/zabbix-6.4.0/
# compile
./configure --prefix=/usr/local/zabbix/ --enable-server --enable-agent --with-net-snmp --with-mysql
make install
Since the default gcc version of CentOS7 is lower than 4.8, it cannot be compiled and installed successfully.
而且重新安装gcc的过程十分漫长，因此我们采用切换gcc版本的方式，无需漫长的手动下载源码编译安装
安装切换gcc版本
安装centos-release-scl
yum install centos-release-scl -y
安装devtoolset，注意，如果想安装10.版本的，就改成devtoolset-10-gcc，以此类推
sudo yum install devtoolset-11-gcc* -y
激活对应的devtoolset，所以你可以一次安装多个版本的devtoolset，需要的时候用下面这条命令切换到对应的版本
scl enable devtoolset-11 bash
查看gcc版本
gcc -v
补充：这条激活命令只对本次会话有效，重启会话后还是会变回原来的4.8.5版本，要想随意切换可按如下操作。
首先，安装的devtoolset是在 /opt/rh 目录下的，如图
每个版本的目录下面都有个 enable 文件，如果需要启用某个版本，只需要执行
source ./enable
直接替换旧的gcc
旧的gcc是运行的 /usr/bin/gcc，所以将该目录下的gcc/g++替换为刚安装的新版本gcc软连接，免得每次enable
mv /usr/bin/gcc /usr/bin/gcc-4.8.5
ln -s /opt/rh/devtoolset-8/root/bin/gcc /usr/bin/gcc
mv /usr/bin/g++ /usr/bin/g++-4.8.5
ln -s /opt/rh/devtoolset-8/root/bin/g++ /usr/bin/g++
gcc --version
g++ --version
跟新完gcc版本后，我们可以顺利完成zabbix6.4的编译安装
安装PHP
由于CentOS7自带PHP版本为5.6，所以需要安装额外的库，也是remi的库
yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum -y install yum-utils
yum-config-manager --disable 'remi-php*'
yum-config-manager --enable remi-php74
yum -y install php php-bcmath php-gd php-xml php-mbstring php-mysqlnd php-ldap
yum -y install curl-devl libxml2 libxml2-devel
需要修改PHP参数（网页预配置必要条件）
vim /etc/php.ini
修改post_max_size为16M
修改max_execution_time为300
修改max_input_time为300
配置httpd
移动前端文件至web服务的根目录并授权
cp -r /usr/local/zabbix/zabbix-6.4.0/ui/* /var/www/html/
chown apache:apache /var/www/html -R
导入数据库架构及数据
mysql -uzabbix -pZabbix@123 zabbix < /usr/local/zabbix/zabbix-6.4.0/database/mysql/schema.sql
mysql -uzabbix -pZabbix@123 zabbix < /usr/local/zabbix/zabbix-6.4.0/database/mysql/images.sql
mysql -uzabbix -pZabbix@123 zabbix < /usr/local/zabbix/zabbix-6.4.0/database/mysql/data.sql
修改配置zabbixserver文件数据库密码
vim /usr/local/zabbix/etc/zabbix_server.conf
# DBPassword= 修改为MySQL的zabbix用户密码
DBPassword=Zabbix@123
开启httpd zabbix
service httpd start
systemctl enable httpd.service
cd /usr/local/zabbix/sbin/
./zabbix_server
网页验证：
访问地址：本机ip:80
按流程进行下一步配置即可
第一步选择中文
必要条件全部OK选点击下一步
数据库配置，输入zabbix用户的密码Zabbix@123后点击下一步
设置zabbix主机名及主题颜色
登录zabbix输入用户密码，默认用户密码：Admin/zabbix
登录成功，进入zabbix界面
