数据库安装配置

安装数据库

wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
yum localinstall mysql57-community-release-el7-8.noarch.rpm -y

检查mysql源是否安装成功

yum repolist enabled | grep "mysql.*-community.*"
yum install mysql-community-server -y

启动MySQL服务

systemctl start mysqld

登录数据库

#查看随机密码
grep 'temporary password' /var/log/mysqld.log

#登陆数据库 
mysql -uroot -p
修改validate_password_policy参数的值
set global validate_password_policy=0;
再修改密码的长度
set global validate_password_length=1;
修改默认密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'xuewenlong@123';
允许root远程登陆*
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'xuewenlong@123' WITH GRANT OPTION;

创建zabbix数据库和用户

mysql –uroot –p
mysql>  create database zabbix character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql> grant all privileges on zabbix.* to 'zabbix'@'localhost' identified by 'zabbix'; 
Query OK, 0 rows affected, 1 warning (0.00 sec) 
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

导入模板数据

方法1

source /usr/share/doc/zabbix-server-mysql-3.4.7/create/schema.sql
source /usr/share/doc/zabbix-server-mysql-3.4.7/create/images.sql
source /usr/share/doc/zabbix-server-mysql-3.4.7/create/data.sql

方法2

zcat /usr/share/docc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
