[root@monitor_53 ~]$ cat /etc/my.cnf
[mysqld]
user = mysql
port = 3306
datadir = /var/lib/mysql
socket = /var/lib/mysql/mysql.sock
pid-file = /var/run/mariadb/mariadb.pid
log-error = /home/mysql/logs/error.log
slow_query_log = on
slow_query_log_file = /home/mysql/logs/slow_query_log.log
long_query_time = 0.1
log_queries_not_using_indexes =1
long_query_time=2
character_set_server=utf8
[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
[mysqldump]
quick
max_allowed_packet = 32M
2.4 初始化数据库
[root@monitor_53 ~]$ systemctl enable mariadb
[root@monitor_53 ~]$ systemctl start mariadb
[root@monitor_53 ~]$ mysql_secure_installation #初始化,配置完成root密码后,一路按Y即可
[root@monitor_53 ~]$ mysql_secure_installation
Enter current password for root (enter for none): 回车
Set root password? [Y/n] 回车
New password: 123456
Re-enter new password: 123456
Remove anonymous users? [Y/n] 回车
Disallow root login remotely? [Y/n] 回车
Remove test database and access to it? [Y/n] 回车
Reload privilege tables now? [Y/n] 回车
Thanks for using MariaDB!
2.5 启动http
[root@monitor_53 ~]$ systemctl start httpd
[root@monitor_53 ~]$ systemctl enable httpd
[root@monitor_53 ~]$ netstat -ntap | egrep '(80|3306)'
3. 安装zabbix
3.1 安装Server、Web、Agent
[root@monitor_53 ~]$ rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
[root@monitor_53 ~]$ yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent
3.2 创建zabbix数据库
[root@monitor_53 ~]$ mysql -uroot -p123456
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to 'zabbix'@'10.0.0.53' identified by 'zabbix';
mysql> flush privileges;
mysql> quit;
3.3 导入初始架构和数据
[root@monitor_53 ~]$ zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -h 10.0.0.53 -uzabbix -p zabbix
3.4 为Zabbix-server配置数据库
[root@monitor_53 ~]$ cp /etc/zabbix/zabbix_server.conf /etc/zabbix/zabbix_server.conf.bak
