1，安装zabbix
2，配置主从
3，监控mysql
4，监控主从
zabbix安装
rpm -ivh
安装lmp
rpm -ivh
rpm -Uvh
yum -y install mysql-server mysql mysql-devel php56w php56w-fpm php56w-mysql php56w-common php56w-gd php56w-mbstring php56w-mcrypt php56w-devel php56w-xml php56w-imAP php56w-pear php56w-snmp
rpm -ivh
安装zabbix-server
rpm -ivh
yum install zabbix zabbix-server zabbix-web zabbix-agent zabbix-web-mysql zabbix-get zabbix-sender
数据库授权
mysql -e "CREATE DATABASE zabbix CHARACTER SET utf8;"
mysql -e "GRANT ALL ON zabbix.* TO 'zuser'@'10.10.230.59' IDENTIFIED BY 'password';"
mysql -e "GRANT ALL ON zabbix.* TO 'zuser'@'localhost' IDENTIFIED BY 'password';"
导入zabbixsql文件，顺序不能错
mysql zabbix < /usr/share/doc/zabbix-server-mysql-2.4.7/create/schema.sql
mysql zabbix < /usr/share/doc/zabbix-server-mysql-2.4.7/create/images.sql
mysql zabbix < /usr/share/doc/zabbix-server-mysql-2.4.7/create/data.sql
修改zabbix配置文件
vim /etc/zabbix/zabbix_server.conf
DBUser=zuser
DBHost=localhost
DBName=zabbix
DBPassword=password
DBSocket=/var/lib/mysql/mysql.sock
启动
service httpd restart
service zabbix-server start
chkconfig --add zabbix-server
chkconfig zabbix-server on
chkconfig --add httpd
chkconfig httpd on
chkconfig --add mysqld
chkconfig mysqld on
chkconfig iptables off
setenforce 0
监控本机：
rpm -ivh
yum -y install zabbix-agent zabbix-sender zabbix
vim /etc/zabbix/zabbix-agentd.conf
Server=192.168.233.130 zabbix-server服务端IP
ServerActive=192.168.233.130 zabbix-server服务端IP
Hostname=zabbix-agent 全局唯一，最好使用dns解析名。这里的hostname主要推送数据
service zabbix-agentd start
一，监控mysql如下：
添加zabbix-agent监控数据库权限，当然你也可给小的权限
GRANT ALL ON *.* TO 'test'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'test'@'127.0.0.1' IDENTIFIED BY 'password';
添加脚本
创建脚本目录
mkdir /etc/zabbix/script/
创建脚本如下：
vim /etc/zabbix/script/chk_mysql.sh
#/bin/bash
DEF="--defaults-file=/etc/zabbix/script/mysql.conf"
MYSQL='/usr/local/webservers/mysql-5.6.19/bin/mysqladmin'
ARGS=1
if [ $# -ne "$ARGS" ];then
echo "Please input one arguement:"
fi
case $1 in
Uptime)
result=`${MYSQL} $DEF status|cut -f2 -d":"|cut -f1 -d"T"`
echo $result
;;

result=`${MYSQL} $DEF extended-status |grep -w "Com_update"|cut -d"|" -f3`
echo $result
;;

result=`${MYSQL} $DEF status |cut -f5 -d":"|cut -f1 -d"O"`
echo $result
;;

echo $result
;;

result=`${MYSQL} $DEF extended-status |grep -w "Com_rollback"|cut -d"|" -f3`
echo $result
;;

result=`${MYSQL} $DEF status|cut -f4 -d":"|cut -f1 -d"S"`
echo $result
;;
Com_insert)
result=`${MYSQL} $DEF extended-status |grep -w "Com_insert"|cut -d"|" -f3`
echo $result
;;

result=`${MYSQL} $DEF extended-status |grep -w "Com_delete"|cut -d"|" -f3`

echo $result

esac
编辑/etc/zabbix/script/mysql.conf
vim /etc/zabbix/script/mysql.conf
[client]
host=localhost
user=test
password='password'
socket = /data/mysql/mysql.sock
agent添加key文件
vim /etc/zabbix/zabbix_agent.d/myql-status.conf
UserParameter=mysql.version,/usr/local/mysql/bin/mysql -V
UserParameter=mysql.ping,/usr/local/mysql/mysqladmin --defaults-file=/etc/zabbix/script/mysql.conf ping | grep -c alive
UserParameter=mysql.status[*],/etc/zabbix/script/chk_mysql.sh $1 $2
修改zabbix-agent.conf
Server=192.168.233.130 zabbix-server服务端IP
ServerActive=192.168.233.130 zabbix-server服务端IP
Hostname=zabbix-agent 全局唯一，最好使用dns解析名。这里的hostname主要推送数据
Include=/usr/local/etc/zabbix_agentd.conf.d/myql-status.conf
测试：
[root@localhost zabbix]# zabbix_get -s 127.0.0.1 -k "mysql.ping"
1
[root@localhost zabbix]# zabbix_get -s 127.0.0.1 -k "mysql.status[Uptime]"
78967
[root@localhost zabbix]#
二，监控mysql从进程
1，安装mysql
tar xf mariadb-5.5.48-linux-x86_64.tar.gz
ln -s mariadb-5.5.48-linux-x86_64 mysql
mkdir -pv /mydata/data
groupadd -r -g 306 mysql
useradd -r -g 306 -u 306 mysql
chown -R mysql.mysql /mydata
cd mysql/
chown -R root.mysql ./*
scripts/mysql_install_db --user=mysql --datadir=/mydata/data
mkdir /etc/mysql
cp support-files/my-large.cnf /etc/mysql/my.cnf
cp support-files/mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
service mysqld start
备份主数据，从导入数据
/usr/local/mysql/bin/mysql < /tmp/zabbix.sql
/usr/local/mysql/bin/mysql
MariaDB [(none)]> CHANGE MASTER TO MASTER_HOST='10.10.230.59',MASTER_USER='repluser',MASTER_PASSWORD='replpass',MASTER_LOG_FILE='master-bin.000003',MASTER_LOG_POS=30578124,MASTER_CONNECT_RETRY=5,MASTER_heartbeat_PERIOD=2;
MariaDB [(none)]> start slave;
安装zabbix
rpm -ivh
yum -y install zabbix-agent zabbix-sender zabbix
创建目录
mkdir /etc/zabbix/script/
脚本mysql_ms.sh
vim /etc/zabbix/script/mysql_ms.sh
#!/bin/bash
/usr/local/mysql/bin/mysql --defaults-file=/etc/zabbix/script/my.conf -e 'show slave status\G' | grep -E "Slave_IO_Running:|Slave_SQL_Running:" | awk '{print $2}' | grep -c Yes
脚本2
vim /etc/zabbix/zabbix_agentd.d/mysql_ms.conf
UserParameter=mysql.ms,/etc/zabbix/script/mysql_ms.sh
授予zabbix监控mysql权限
MariaDB [(none)]> GRANT ALL ON *.* TO 'test'@'127.0.0.1' IDENTIFIED BY 'password';
my.conf配置文件
[root@localhost script]# cat my.conf
[client]
host=127.0.0.1
user=test
password='password'
socket = /tmp/mysql.sock
[root@localhost script]#
test
[root@localhost zabbix]# zabbix_get -s 10.10.230.38 -k "mysql.ms"
2
[root@localhost zabbix]#
打开web界面点击create host 添加一台主机，而后Items–>Create item
邮件通知内容：
