步骤一：
1. 安装mysql
首先移除mariadb
yum remove mariadb-libs.x86_64
安装mysql的源
wget https://repo.mysql.com//mysql80-community-release-el7-2.noarch.rpm
yum localinstall mysql80-community-release-el7-2.noarch.rpm
安装yum-config-manager，然后修改要安装的mysql版本为5.7
[root@freesaber tmp]# yum search yum-config-manager
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
========================================== Matched: yum-config-manager ==========================================
yum-utils.noarch : Utilities based around the yum package manager
[root@freesaber tmp]# yum install yum-utils.noarch
yum-config-manager --disable mysql80-community
yum-config-manager --enable mysql57-community
安装mysql5.7数据库
yum install mysql-community-server
启动数据库
systemctl start mysqld.service
systemctl status mysqld.service
查看数据库初始密码
grep "password" /var/log/mysqld.log
登录mysql数据库修改初始密码
mysql -uroot -p
ALTER USER 'root'@'localhost' IDENTIFIED BY 'PASSWORD';
注：mysql5.7默认对密码复杂度有要求
查看root账户，修改root账户，允许任何主机进行连接
mysql> use mysql;
Database changed
mysql> select Host,User from user \G;
*************************** 1. row ***************************
Host: localhost
User: mysql.infoschema
*************************** 2. row ***************************
Host: localhost

*************************** 4. row ***************************

User: root
4 rows in set (0.00 sec)
mysql> update user set Host = '%' where Host = 'localhost' and User = 'root';
Query OK, 1 row affected (0.04 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select Host,User from user \G;
*************************** 1. row ***************************
Host: %
User: root
*************************** 2. row ***************************
Host: localhost

*************************** 3. row ***************************
Host: localhost
User: mysql.session
*************************** 4. row ***************************
Host: localhost
User: mysql.sys
4 rows in set (0.00 sec)
刷新权限
FLUSH PRIVILEGES;
步骤二：
1.安装zabbix
由于zabbix官方网站在国内下载比较慢，而且yum安装用zabbix官方源经常安装失败，我们使用阿里的镜像站。
rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm
下载安装后/etc/yum.repo目录下会生成zabbix.repo文件，修改zabbix.repo文件，更换yum源为aliyun。
cat /etc/yum.repos.d/zabbix.repo
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
[zabbix-debuginfo]
name=Zabbix Official Repository debuginfo - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/debuginfo/
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
gpgcheck=1
[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1
或者清华软件源
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.4/rhel/7/x86_64/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
[zabbix-debuginfo]
name=Zabbix Official Repository debuginfo - $basearch
baseurl=https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.4/rhel/7/x86_64/debuginfo/
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
gpgcheck=1
[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.4/rhel/7/x86_64/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1
安装fping，以免出错
yum list | grep epel-release
yum remove epel-release
yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install -y iksemel fping libiksemel net-snmp-utils
安装zabbix-server、agent和apache
yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-agent zabbix-get
2.配置zabbix
创建初始数据库
# mysql -uroot -p
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'PASSWORD';
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/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
为Zabbix server配置数据库，编辑配置文件 /etc/zabbix/zabbix_server.conf
vim /etc/zabbix/zabbix_server.conf
修改此行 DBPassword=Password
配置PHP上海时区,编辑配置文件
vim /etc/httpd/conf.d/zabbix.conf
修改此行 php_value date.timezone Asia/Shanghai
vi /etc/php.ini
修改此行 date.timezone = Asia/Shanghai
启动Zabbix server和agent进程并设置开机启动
systemctl start zabbix-server zabbix-agent httpd
systemctl enable zabbix-server zabbix-agent httpd
登录并配置zabbix前端，注意配置zabbix数据库密码，其他全部下一步即可
image
登录zabbix页面，默认用户为Admin，密码为zabbix，用yum安装zabbix的路径是http://x.x.x.x/zabbix/
这里放个连接，文章是以mariabd作为后段数据库，其他无太多区别
