使用nagios监控mysql主从,在监控主机上需要安装nrpe软件包以及nagios软件包,,安装步骤就不多说了,下面进入正题
 
在监控主机上:
 
首先定义主机:
 
vim /usr/local/nagios/etc/objects/localhost.cfg       
define host {
        host_name                    joker
        alias                              test
        address                        192.168.xx.xx
        check_command          check-host-alive
        notification_options      d,u,r
        check_interval                1
        max_check_attempts      2
        contact_groups                admins
        notification_interval  10
        notification_period    24x7
 }
 
定义服务:
 
define service {
        host_name          joker
        service_description    nrpe
        check_period        24x7
        normal_check_interval  2
        retry_check_interval    1
        max_check_attempts      5
        notification_period    24x7
        notification_options    w,u,c,r
        check_command      check_nrpe!check_mysql
 }
 
定义command:
 
define command {
        command_name    check_nrpe
        command_line    /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
 }
 
在被监控主机上:
 
安装nrpe
 tar fvxz nrpe*.tar.gz
 ./configure --prefix=/usr/local/nagios
 useradd nagios
 make all
 make install
 make install-daemon
 make install-daemon-config
 make install-xinetd
 
scp /usr/local/nagios/libexec/check_nrpe  root@192.168.18.105:/usr/local/nagios/libexec
 
vim /etc/xinetd.d/nrpe
 service nrpe
 {
        flags          = REUSE
        socket_type    = stream   
        port            = 5666   
        wait            = no
        user            = nagios
        group          = nagios
        server          = /usr/local/nagios/bin/nrpe
        server_args    = -c /usr/local/nagios/etc/nrpe.cfg --inetd
        log_on_failure  += USERID
        disable        = no
        only_from      = 192.168.18.105 
}
 vim /etc/services
 
在最后添加nrpe 5666/tcp
 service xinetd restart
 
vim /usri/local/nagios/etc/nrpe.cfg
 command[check_mysql]=/usr/local/nagios/libexec/check_mysql
 
vim /usr/local/nagios/libexec/check_mysql
 #!/bin/bash
 master=`mysql -h 192.168.18.165 -u hello -p123 -e 'show master status' &> /tmp/123 | awk 'NR==2{print $2}' /tmp/123`
 slave=`mysql -e 'show slave status' &> /tmp/234 | awk =F: '{if($1~/Exec/)print $2}' /tmp/234`
 if [ $master -eq $slave ]; then
    echo "ok"
    rm -fr /tmp/123
    rm -fr /tmp/234
    exit 0
 else
    echo "error"
    mv /tmp/123 /tmp/err1
    mv /tmp/234 /tmp/err2
    exit 2
 
最后进行测试,本人亲测OK~~~

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Explain InnoDB Full-Text Search capabilities. Explain InnoDB Full-Text Search capabilities. Apr 02, 2025 pm 06:09 PM

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
