一、Zabbix特性简介Zabbix可以监控网络和服务的监控状况. Zabbix利用灵活的告警机制,允许用户对事件发送基于Email的告警. 这样可以保证快速的对问题作出相应. Zabbix可以利用存储数据提供杰出的报告及图形化方式. 这一特性将帮助用户完成容量规划。二、本次实战环境
名称 | 主机名 | ip |
zabbix server | server134 | 192.168.159.134 |
zabbix agent | server135 | 192.168.159.135 |
三、服务器安装步骤3.1、安装开发软件包及zabbix安装所依赖的软件包[root@server134 ~]yum groupinstall "Development Tools"[root@server134 ~]# yum install php-common php-odbc php-pear curl curl-devel perl-DBI php-xml ntpdate php-bcmath mysql httpd php-mysql mysql-server php php-gd ntpdate3.2、同步服务端的时间,避免时间不同导致不可用的监控数据[root@server134 ~]# ntpdate pool.ntp.org8 Feb 18:41:20 ntpdate[2871]: step time server 85.199.214.100 offset 4.665038 sec3.3、创建zabbix服务运行的用户和组[root@server134 ~]# groupadd -g 201 zabbix[root@server134 ~]# useradd -g zabbix -u 201 -m zabbix3.4、启动mysql、创建zabbix数据库、设置用户密码访问[root@server134 ~]# /etc/init.d/mysqld start[root@server134 ~]# mysql -u root -pmysql> create database zabbix character set utf8;Query OK, 1 row affected (0.08 sec)mysql> grant all privileges on *.* to "zabbix"@"%" identified by "zishang77";ERROR 1819 (HY000): Your password does not satisfy the current policy requirements因本文使用的是mysql5.7,MySQL默认开启了validate_password插件,进行密码验证,需要很强的密码强度才能通过认证此版本对密码的要求比较严格,本文做了如下调整查阅官方文档后发现有以下三种密码策略:
Policy | Tests Performed |
0 or LOW | Length |
1 or MEDIUM | Length; numeric, lowercase/uppercase, and special characters |
2 or STRONG | Length; numeric, lowercase/uppercase, and special characters; dictionary file |
mysql> select @@validate_password_policy;+----------------------------+| @@validate_password_policy |+----------------------------+| MEDIUM |+----------------------------+1 row in set (0.00 sec)mysql> SHOW VARIABLES LIKE "validate_password%";+--------------------------------------+--------+| Variable_name | Value |+--------------------------------------+--------+| validate_password_check_user_name | OFF || validate_password_dictionary_file | || validate_password_length | 8 || validate_password_mixed_case_count | 1 || validate_password_number_count | 1 || validate_password_policy | MEDIUM || validate_password_special_char_count | 1 |+--------------------------------------+--------+7 rows in set (0.08 sec)mysql> set global validate_password_policy=0;#设置密码的策略为lowQuery OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_mixed_case_count=0#设置指定了密码中大小字母的长度 -> ;Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_number_count=2;#设置指定了密码中数据的长度Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_special_char_count=0;#设置密码中的特殊字符为0Query OK, 0 rows affected (0.00 sec)mysql> set global validate_password_length=6;#设置密码长度为6Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)mysql> grant all privileges on *.* to "zabbix"@"%" identified by "zabbix";Query OK, 0 rows affected, 1 warning (0.06 sec)
3.5、安装zabbix,并导入zabbix包中的数据到mysql的zabbix数据库中[root@server134 mnt]# tar zxvf zabbix-2.4.8.tar.gz[root@server134 mnt]# cd zabbix-2.4.8[root@server134 mnt]# cd zabbix-2.4.8[root@server134 zabbix-2.4.8]# mysql -uzabbix -pzabbix zabbix<database/mysql/schema.sqlmysql: [Warning] Using a password on the commnd line interface can be insecure.[root@server134 zabbix-2.4.8]# mysql -uzabbix -pzabbix zabbix<database/mysql/images.sqlmysql: [Warning] Using a password on the command line interface can be insecure.[root@server134 zabbix-2.4.8]# mysql -uzabbix -pzabbix zabbix<database/mysql/data.sqlmysql: [Warning] Using a password on the command line interface can be insecure.[root@server134 zabbix-2.4.8]# ./configure --sysconfdir=/etc/zabbix --enable-server --enable-agent --with-net-snmp --with-libcurl --with-mysql --with-ssh2 --enable-java
configure: error: MySQL library not found[root@server134 zabbix-2.4.8]# yum install mysql-devel[root@server134 zabbix-2.4.8]# make &&make install
3.6、Copy zabbixserver端跟agent端的启动脚本,并设置执行权限[root@server134 zabbix-2.4.8]# cp misc/init.d/tru64/zabbix_agentd /etc/init.d/[root@server134 zabbix-2.4.8]# cp misc/init.d/tru64/zabbix_server /etc/init.d/[root@server134 zabbix-2.4.8]# chmod +x /etc/init.d/zabbix_*[root@server134 zabbix-2.4.8]# cp misc/init.d/tru64/zabbix_agentd /etc/init.d/[root@server134 zabbix-2.4.8]# cp misc/init.d/tru64/zabbix_server /etc/init.d/[root@server134 zabbix-2.4.8]# chmod +x /etc/init.d/zabbix_*[root@server134 zabbix-2.4.8]# mkdir /var/www/html/zabbix[root@server134 zabbix-2.4.8]# cp -a frontends/php/* /var/www/html/zabbix/[root@server134 zabbix-2.4.8]# chown -R apache.apache /var/www/html/zabbix/
3.7、调整使用zabbix服务所需的php参数[root@server134 zabbix-2.4.8]# vi /etc/php.inidate.timezone = Asia/Shanghaimax_execution_time = 300max_input_time = 300post_max_size = 32Mmemory_limit = 128Mmbstring.func_overload = 0[root@server134 zabbix-2.4.8]# service httpd restart
3.8、调整zabbix服务所需的参数[root@server134 ~]# vi /etc/zabbix/zabbix_server.confDBHost=192.168.159.134DBName= zabbixDBUser=zabbixDBPassword=zabbixDBSocket=/var/lib/mysql/mysql.sockStartPollers=30 开启多线程数,一般不要超过30个StartTrappers=20 trapper线程数StartPingers=10 fping线程数StartDiscoverers=120 ListenIP=0.0.0.0MaxHousekeeperDelete=5000 CacheSize=128M 用来保存监控数据的缓存数,根据监控主机的数量适当调整StartDBSyncers=8 数据库同步时间HistoryCacheSize=128M TrendCacheSize=128M 总趋势缓存大小HistoryTextCacheSize=128MAlertScriptsPath=/etc/zabbix/alertscriptsLogSlowQueries=1000[root@server134 ~]# service httpd restart[root@server134 ~]# /etc/init.d/zabbix_server start3.8、图形化安装zabbixhttp://192.168.159.134/zabbix/setup.php
