Linux monitoring platform introduction

Common open source monitoring software

• cacti、nagios、zabbix、smokeping、open-falcon等等
• cacti and smokeping are biased towards basic monitoring, and the mapping is very beautiful
• The cacti, nagios, and zabbix server monitoring centers require PHP environment support. Both zabbix and cacti require mysql as data storage. Nagios does not need to store historical data, but focuses on the status of services or monitoring items. Zabbix will obtain the data of services or monitoring items. The data will be recorded in the database, so that it can be graphed
• open-falcon was developed by Xiaomi. After open source, it is sought after by many large companies and operation and maintenance engineers. It is suitable for large enterprises. Big companies such as Didi, 360, Sina Weibo, JD.com are using this monitoring software, and it is worth studying.

Introduction to zabbixx monitoring

• C/S architecture, based on C++ development, monitoring center supports web interface configuration and management
• A single server node can support tens of thousands of clients
• Official documentation https://www.zabbix.com/manuals
• 5 components
• zabbix-server monitoring center, receives the information reported by the client, and is responsible for configuration, statistics, and operation data
• Data storage, storing data, such as mysql
• The web interface and the web UI are also added. The operation configuration under the web interface is the main reason why zabbix is ​​easy to use.
• zabbix-proxy is an optional component, which can replace the function of zabbix-server and reduce the pressure on the server
• The zabbix-agent client software is responsible for collecting the data of each monitoring service or project and reporting it

install zabbix

• Official website download address www.zabbix.com/download
• wget http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
• rpm -ivh zabbix-release-3.2-1.el7.noarch.rpm
• yum install -y zabbix-agent zabbix-get zabbix-server-mysql zabbix-web zabbix-web-mysql
• Will install httpd and php together
• vi /etc/my.cnf character_set_server=utf9
• After restarting the mysqld service, enter the mysql command line and create the zabbix library
• create database zabbix character set utf8;
• create user again
• grant all on zabbix.* to 'zabbix'@'127.0.0.1' identified by 'user-zabbix';
• Import Data
• cd /usr/share/doc/zabbix-server-mysql-3.2.7
• gzip -d create.sql.gz
• mysql -uroot -pxxx zabbix < create.sql
