启动数据库
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/messages

导入数据库文件
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.rpm
rpm -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-devel
yum install -y httpd php php-mysql
yum -y install zabbix-server-mysql
yum -y install zabbix-agent
安装这些以后,就能有create.sql.gz包
cd /usr/share/doc/zabbix-server-mysql-4.0.29
gunzip create.sql.gz
mysql -uzabbix -pRoot@123456 -h127.0.0.1
use zabbix
source create.sql
Mysql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@123456
mysql> 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 数据库从库的配置
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
