先启动主节点，备节点暂时不启动。[root@zabbix-mysql01 ~]# systemctl start mysqld[root@zabbix-mysql01 ~]# 修改密码
首先查找临时密码tail -100 /var/log/messagesMar 19 22:30:11 zabbix-mysql01 mysqld_pre_systemd: 2021-03-19T14:30:11.846201Z 0 [System] [MY-013169] [Server] /usr/sbin/mysqld (mysqld 8.0.23) initializing of server in progress as process 3341Mar 19 22:30:11 zabbix-mysql01 mysqld_pre_systemd: 2021-03-19T14:30:11.847519Z 0 [Warning] [MY-013242] [Server] --character-set-server: 'utf8' is currently an alias for the character set UTF8MB3, but will be an alias for UTF8MB4 in a future release.

导入数据库文件,该文件需要安装zabbix插件，可参考之前安装的步骤进行操作wget http://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpmrpm -ivh zabbix-release-4.0-2.el7.noarch.rpm安装yum -y install gcc make openldap-devel libssh2-devel net-snmp-devel curl-devel unixODBC-devel OpenIPMI-devel java-devel net-snmp-devel openldap-devel gnutls-devel sqlite-devel sqlite-devel curl-devel libxml2-devel libevent-devel openssl-develyum install -y httpd php php-mysqlyum -y install zabbix-server-mysqlyum -y install zabbix-agent安装这些以后，就能有create.sql.gz包cd /usr/share/doc/zabbix-server-mysql-4.0.29gunzip create.sql.gzmysql -uzabbix -pRoot@123456 -h127.0.0.1use zabbixsource create.sqlMysql数据库主库配置
以下操作在主服务器上进行停止Mysql主库服务systemctl stop mysqld同步主库文件到从库
[root@zabbix-mysql01 ~]# rsync -av -e "ssh -p 22" /var/lib/mysql/ root@10.10.10.202:/var/lib/mysql/
启动主库服务
[root@zabbix-mysql01 ~]# systemctl start mysqld主库上配置复制数据库用户
[root@zabbix-mysql01 ~]# mysql -uroot -pRoot@123456mysql> create user 'repl'@'%' identified with mysql_native_password by 'Root@123456';Query OK, 0 rows affected (0.00 sec)mysql> grant replication client,replication slave on *.* to 'repl'@'%';Query OK, 0 rows affected (0.00 sec)mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)mysql> 查看主库运行状态

启动从节点
需要从节点的/var/lib/mysql/auto.cnf[root@zabbix-mysql02 mysql]# systemctl start mysqld连接主库
