CentOS 6.5下 Zabbix 3.0监控部署

1、准备LAMP环境

（1）安装php

Zabbix 3.0对PHP的要求最低为5.4，而CentOS默认为5.3.3，完全不满足要求，故需要利用第三方资源，将PHP升级到5.4以上

rpm -ivh http://repo.webtatic.com/yum/el6/latest.rpm
yum install php56w php56w-gd php56w-mysql php56w-bcmath php56w-mbstring php56w-xml php56w-ldap
vim /etc/php.ini
date.timezone = Asia/Shanghai
post_max_size = 32M
max_execution_time = 300
max_input_time = 300
always_populate_raw_post_data = -1
service php-fpm start  #启动服务
chkconfig php-fpm on

（2）安装MySQL

我安装的是MySQL5.7,安装方式是二进制安装。

此处省略了MySQL安装的过程

（3）在MySQL种创建zabbix所需要的库和用户

mysql> CREATE DATABASE zabbix CHARACTER SET utf8 COLLATE utf8_bin;
mysql> GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@localhost IDENTIFIED BY 'zabbix';
mysql> flush privileges;  
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| hp_cougar_transfer |
| mysql              |
| performance_schema |
| sys                |
| t1                 |
| test               |
| zabbix             |
+--------------------+

（4）安装apache

#yum install httpd libxml2-devel net-snmp-devel libcurl-devel

配置apache

[root@localhost /]# vim /etc/httpd/conf/httpd.conf
ServerName 127.0.0.1
DirectoryIndex index.html index.html.var index.php
启动apache
[root@localhost /]# /etc/init.d/httpd start
Starting httpd:                                            [  OK  ]

（5）创建zabbix用户

[root@localhost /]# groupadd zabbix
[root@localhost /]# useradd -g zabbix zabbix

（6）依赖包安装

# yum -y install gcc mysql-community-devel libxml2-devel unixODBC-devel net-snmp-devel libcurl-devel libssh2-devel OpenIPMI-devel openssl-devel openldap-devel

（7）安装zabbix

#wget http://sourceforge.net/projects/zabbix/files/ZABBIX%20Latest%20Stable/3.0.3/zabbix-3.0.3.tar.gz
解压到当前目录：
[root@localhost tools]#tar -zxvf zabbix-3.0.3.tar.gz
[root@localhost tools]#cd zabbix-3.0.3
[root@localhost zabbix-3.0.3]#./configure --prefix=/usr/local/zabbix --sysconfdir=/etc/zabbix/ --enable-server --enable-agent --with-net-snmp --with-libcurl --with-mysql --with-libxml2
[root@localhost zabbix-3.0.3]#make &&make install

编译过程可能遇到的问题：

checking size of void *... 8
checking for mysql_config... no
configure: error: MySQL library not found

解决方法：

安装 mysql-devel
#yum install mysql-devel -y

（8）导入zabbix库

[root@localhost mysql]# pwd
/home/tools/zabbix-3.0.3/database/mysql
[root@localhost mysql]# ll
total 3012
-rw-r--r-- 1 1000 1000  990351 May 18  2016 data.sql
-rw-r--r-- 1 1000 1000 1978341 May 18  2016 images.sql
-rw-r--r-- 1 1000 1000  113197 May 18  2016 schema.sql
[root@localhost mysql]# mysql -uzabbix -pzabbix zabbix -h localhost < database/mysql/schema.sql
[root@localhost mysql# mysql -uzabbix -pzabbix zabbix -h localhost< database/mysql/images.sql
[root@localhost mysql# mysql -uzabbix -pzabbix zabbix  -h localhost< database/mysql/data.sql

（9）配置zabbix_server

vim /etc/zabbix/zabbix_server.conf
DBHost=192.168.2.11   #数据库IP地址
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/home/mysql57/run/mysql.sock      #和MySQL安装的配置文件保持一致
ListenIP=192.168.2.11  zabbix server ip地址
StartIPMIPollers=10
StartPollersUnreachable=10
StartTrappers=10
StartPingers=10
StartDiscoverers=10
CacheSize=256M
StartDBSyncers=40
HistoryCacheSize=128M
TrendCacheSize=128M
HistoryTextCacheSize=128M
ValueCacheSize=128M
Timeout=30
AlertScriptsPath=/etc/zabbix/alertscripts      //修改
ExternalScripts=/etc/zabbix/externalscripts    //修改
LogSlowQueries=10000
StartProxyPollers=50

创建zabbix所需要的脚本目录

#mkdir /etc/zabbix/alertscripts 
#mkdir /etc/zabbix/externalscripts

#ln -s /usr/local/zabbix/sbin/* /usr/sbin/

#######添加Zabbix服务器和Zabbix代理启动脚本
#cp /home/tools/zabbix-3.0.3/misc/init.d/Fedora/core/zabbix_* /etc/init.d/  #复制服务启动脚本
#chmod +x /etc/init.d/zabbix_*
#sed -i "s@BASEDIR=/usr/local@BASEDIR=/usr/local/zabbix@g" /etc/init.d/zabbix_server

(10)配置web

vim /etc/httpd/conf/httpd.conf
ServerName 127.0.0.1
DocumentRoot  "/var/www/html"

（11）创建一个新的web前端文件

#mkdir -p /var/www/html/zabbix
#cp -r /home/tools/zabbix-3.0.3/frontends/php/* /var/www/html/zabbix/

设置Apache作为Web用户接口文件的所有者

#chown -R apache:apache /var/www/html/zabbix

添加权限给Zabbix Web界面执行文件

#chmod +x /var/www/html/zabbix/conf/

添加Zabbix服务器和Zabbix代理服务器

#chkconfig --add /etc/init.d/zabbix_server
#chkconfig --add /etc/init.d/zabbix_server
#chkconfig httpd on
#chkconfig zabbix_server on
#chkconfig zabbix_agentd on

启动zabbix_server

/etc/init.d/zabbix_server start    #报错
Starting zabbix_server:  /etc/init.d/functions: line 546: /usr/local/sbin/zabbix_server: No such file or directory
                                                           [FAILED]
# vim /etc/init.d/zabbix_server
BASEDIR=/usr/local/zabbix     #更改下路径

 
# /etc/init.d/zabbix_server start
Starting zabbix_server:                                    [  OK  ]

2、Zabbix Sever Web界面安装

（1）在web界面配置zabbixserver

用浏览器访问：http://192.168.2.11/zabbix/setup.php

需要确认每个Required都是ok的才会显示Next按钮，如果有Fail的需要完善系统要求

解决方法：vim /etc/php.ini

post_max_size =16M
max_input_time =300
max_execution_time = 300
date.timezone = Asia/Shanghai

解决方法：always-populate-raw-post-data must be set -1 的问题：

#vim /var/www/html/zabbix/include/classes/setup/CFrontendSetup.php
找到第366行
如下：
public function checkPhpAlwaysPopulateRawPostData() {             
    $current = ini_get('always_populate_raw_post_data');  

    $current = -1;      ###添加的内容          
     return ['name' => _('PHP always_populate_raw_post_data'), 'current' => ($current != -1) ? _('on') : _('off'),                     
    'required' => _('off'),                         
   'result' => ($current != -1) ? self::CHECK_FATAL : self::CHECK_OK,                         
  'error' => _('PHP always_populate_raw_post_data must be set to -1.')                 ];         
  }
