Zabbix 3.0 for percona-server TokuDB

Zabbix 3.0 for percona-server TokuDB


安装perconna源
[root@linux-node1 ~]# yum install http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm


安装依赖
[root@linux-node1 ~]# yum install epel-release -y
[root@linux-node1 ~]# yum install jemalloc -y

+++++++++++++++++++++++++++++++++++++++++++++++++
TokuDB storage engine requires libjemalloc library 3.3.0 or greater. If the version in the distribution repository is lower than that you can use one from Percona Software Repositories or download it from somewhere else.

If the libjemalloc wasn’t installed and enabled before it will be automatically installed when installing the TokuDB storage engine package by using the apt` or yum package manager, but Percona Server instance should be restarted for libjemalloc to be loaded. This way libjemalloc will be loaded with LD_PRELOAD. You can also enable libjemalloc by specifying malloc-lib variable in the [mysqld_safe] section of the my.cnf file:

[mysqld_safe]
malloc-lib= /path/to/jemalloc

关闭大页内存
[root@linux-node1 ~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled
[root@linux-node1 ~]# echo never > /sys/kernel/mm/transparent_hugepage/defrag

+++++++++++++++++++++++++++++++++++++++++++++++++
TokuDB won’t be able to start if the transparent huge pages are enabled. Transparent huge pages is feature available in the newer kernel versions. You can check if the Transparent huge pages are enabled with:
$ cat /sys/kernel/mm/transparent_hugepage/enabled
 [always] madvise never
If transparent huge pages are enabled and you try to start the TokuDB engine you’ll get the following message in you error.log:
Transparent huge pages are enabled, according to /sys/kernel/mm/redhat_transparent_hugepage/enabled
Transparent huge pages are enabled, according to /sys/kernel/mm/transparent_hugepage/enabled
You can disable transparent huge pages permanently by passing transparent_hugepage=never to the kernel in your bootloader (NOTE: For this change to take an effect you’ll need to reboot your server).

You can disable the transparent huge pages by running the following command as root (NOTE: Setting this will last only until the server is rebooted):

echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

安装percona数据库及tokudb插件
[root@linux-node1 ~]# yum install Percona-Server-tokudb-57.x86_64


启动mysql
[root@linux-node1 ~]# systemctl start mysqld


登录并更改密码和过期策略
登录：
[root@linux-node1 ~]# mysql -u root -p
,c!)fa/Cd9kD


更改密码及过期策略：
SET PASSWORD = PASSWORD('Qwe_1234');
ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
flush privileges;


配置root用户远程登录（只是为了测试，不代表生产操作）
grant all privileges on *.* to root@"%" identified by "Qwe_1234";


测试本地登录与远程登录(我数据库IP为10.0.0.12)
[root@linux-node1 ~]# mysql -uroot -pQwe_1234
[root@linux-node1 ~]# mysql -uroot -pQwe_1234 -h 10.0.0.12 -P3306


加载插件
[root@linux-node1 ~]# ps_tokudb_admin --enable -uroot -pPassw0rd

添加zabbix用户
grant all on zabbix.* to zabbix@'localhost' identified by 'Zabbix_pass123';


创建数据库：
create database zabbix charset utf8;

注意：如果使用tokudb，需要将sql脚本中的InnoDB替换为tokudb
[root@linux-node1 ~]# mysql -uroot -pQwe_1234


重启zabbix相关服务
[root@linux-node1 ~]# systemctl restart zabbix-server
[root@linux-node1 ~]# systemctl restart zabbix-agent
[root@linux-node1 ~]# systemctl restart httpd


web登录配置zabbix（略）
