二.安装percona
1>.percona官网文档
安装教程: https://www.percona.com/doc/percona-monitoring-plugins/LATEST/zabbix/index.html#installation-instructions
下载地址: https://www.percona.com/downloads/ 插件地址: https://www.percona.com/doc/percona-monitoring-plugins/LATEST/zabbix/index.html
2>.下载percona
[root@node203.yinzhengjie.org.cn ~]# ll total 0 [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]# wget https://www.percona.com/downloads/percona-monitoring-plugins/percona-monitoring-plugins-1.1.8/binary/redhat/7/x86_64/percona-zabbix-templates-1.1.8-1.noarch.rpm --2020-02-29 15:15:55-- https://www.percona.com/downloads/percona-monitoring-plugins/percona-monitoring-plugins-1.1.8/binary/redhat/7/x86_64/percona-zabbix-templates-1.1.8-1.noarch.rpm Resolving www.percona.com (www.percona.com)... 74.121.199.234 Connecting to www.percona.com (www.percona.com)|74.121.199.234|:443... connected. HTTP request sent, awaiting response... 200 OK Length: 28296 (28K) [application/x-redhat-package-manager] Saving to: ‘percona-zabbix-templates-1.1.8-1.noarch.rpm’ 100%[====================================================================================================================================================================================================================================>] 28,296 104KB/s in 0.3s 2020-02-29 15:15:56 (104 KB/s) - ‘percona-zabbix-templates-1.1.8-1.noarch.rpm’ saved [28296/28296] [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]# ll total 28 -rw-r--r-- 1 root root 28296 Jan 10 2018 percona-zabbix-templates-1.1.8-1.noarch.rpm [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]#
3>.安装percona
[root@node203.yinzhengjie.org.cn ~]# ll total 28 -rw-r--r-- 1 root root 28296 Jan 10 2018 percona-zabbix-templates-1.1.8-1.noarch.rpm [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]# rpm -ivh percona-zabbix-templates-1.1.8-1.noarch.rpm warning: percona-zabbix-templates-1.1.8-1.noarch.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY Preparing... ################################# [100%] Updating / installing... 1:percona-zabbix-templates-1.1.8-1 ################################# [100%] Scripts are installed to /var/lib/zabbix/percona/scripts Templates are installed to /var/lib/zabbix/percona/templates [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]# rpm -qpl percona-zabbix-templates-1.1.8-1.noarch.rpm warning: percona-zabbix-templates-1.1.8-1.noarch.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY /var/lib/zabbix/percona /var/lib/zabbix/percona/scripts /var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php /var/lib/zabbix/percona/templates /var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf /var/lib/zabbix/percona/templates/zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.8.xml [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]#
三.将percona的插件集成到zabbix agent端
1>.安装zabbix agent服务
CentOS运行环境博主推荐阅读: https://www.cnblogs.com/yinzhengjie2020/p/12344057.html Ubuntu运行环境博主推荐阅读: https://www.cnblogs.com/yinzhengjie2020/p/12309682.html
2>.将percona的配置文件拷贝到zabbix agent的子配置文件目录并重启zabbix agent服务使得配置文件生效
[root@node203.yinzhengjie.org.cn ~]# cp /var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/ [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]# systemctl restart zabbix-agent.service [root@node203.yinzhengjie.org.cn ~]#
3>.配置MySQL的用户名和密码,我root用户密码为空，因此直接mysql_pass的值直接給空串即可。
[root@node203.yinzhengjie.org.cn ~]# vim /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php.cnf [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]# cat /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php.cnf <?php $mysql_user = 'root'; $mysql_pass = ''; [root@node203.yinzhengjie.org.cn ~]# [root@node203.yinzhengjie.org.cn ~]#
4>.安装php环境,否则会运行报错，如下图所示
