一、Zabbix特性簡介
Zabbix可以監控網絡和服務的監控狀況. Zabbix利用靈活的告警機制，允許用戶對事件發送基於Email的告警. 這樣可以保證快速的對問題作出相應. Zabbix可以利用存儲數據提供傑出的報告及圖形化方式. 這一特性將幫助用戶完成容量規劃。
二、本次實戰環境
名稱 主機名 ip zabbix server server134 192.168.159.134 zabbix agent server135 192.168.159.135三、服務器安裝步驟
3.1、安裝開發軟件包及zabbix安裝所依賴的軟件包
[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 ntpdate
3.2、同步服務端的時間，避免時間不同導致不可用的監控數據
[root@server134 ~]# ntpdate pool.ntp.org
8 Feb 18:41:20 ntpdate[2871]: step time server 85.199.214.100 offset 4.665038 sec
3.3、創建zabbix服務運行的用戶和組
[root@server134 ~]# groupadd -g 201 zabbix
[root@server134 ~]# useradd -g zabbix -u 201 -m zabbix
3.4、啟動mysql、創建zabbix數據庫、設置用戶密碼訪問
[root@server134 ~]# /etc/init.d/mysqld start
[root@server134 ~]# mysql -u root -p
mysql> 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默認開啟了validate_password插件，進行密碼驗證，需要很強的密碼強度才能通過認證此版本對密碼的要求比較嚴格，本文做了如下調整
查閱官方文檔後發現有以下三種密碼策略：
Policy Tests Performed0 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;#設置密碼的策略為low
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_mixed_case_count=0#設置指定了密碼中大小字母的長度
-> ;
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_number_count=2;#設置指定了密碼中數據的長度
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_special_char_count=0;#設置密碼中的特殊字符為0
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_length=6;#設置密碼長度為6
Query 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、安裝zabbix，並導入zabbix包中的數據到mysql的zabbix數據庫中
[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.sql
mysql: [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.sql
mysql: [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.sql
mysql: [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端的啟動腳本，並設置執行權限
[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、調整使用zabbix服務所需的php參數
[root@server134 zabbix-2.4.8]# vi /etc/php.ini
date.timezone = Asia/Shanghai
max_execution_time = 300
max_input_time = 300
post_max_size = 32M
memory_limit = 128M
mbstring.func_overload = 0
[root@server134 zabbix-2.4.8]# service httpd restart
3.8、調整zabbix服務所需的參數
[root@server134 ~]# vi /etc/zabbix/zabbix_server.conf
DBHost=192.168.159.134
DBName= zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/var/lib/mysql/mysql.sock
StartPollers=30 開啟多線程數，一般不要超過30個
StartTrappers=20 trapper線程數
StartPingers=10 fping線程數
StartDiscoverers=120
ListenIP=0.0.0.0
MaxHousekeeperDelete=5000
CacheSize=128M 用來保存監控數據的緩存數，根據監控主機的數量適當調整
StartDBSyncers=8 數據庫同步時間
HistoryCacheSize=128M
TrendCacheSize=128M 總趨勢緩存大小
HistoryTextCacheSize=128M
AlertScriptsPath=/etc/zabbix/alertscripts
LogSlowQueries=1000
[root@server134 ~]# service httpd restart
[root@server134 ~]# /etc/init.d/zabbix_server start
3.8、圖形化安裝zabbix
