zabbix4.0的安裝與配置過程

#安裝zabbix監控首先的先安裝LNMP環境，在這裏我採用事先準備好的腳本進行安裝LNMP環境 腳本內容如下：

###################################################################################################This is a lnmp-install~

以上爲lnmp環境的搭建，不要準備包，全部在線下載，整個過程最多30分鐘，這個只是基本的lnmp環境

如果說要安裝zabbix4.0的話還需要滿足他的先決條件，在這裏我們一步步的來，遇到阻擋了再去安裝。

zabbix4.0的先決條件先貼出來

Pre-requisite	Minimum value	Description
PHP version	5.4.0
PHP memory_limit option	128MB	In php.ini: memory_limit = 128M
PHP post_max_size option	16MB	In php.ini: post_max_size = 16M
PHP upload_max_filesize option	2MB	In php.ini: upload_max_filesize = 2M
PHP max_execution_time option	300 seconds (values 0 and -1 are allowed)	In php.ini: max_execution_time = 300
PHP max_input_time option	300 seconds (values 0 and -1 are allowed)	In php.ini: max_input_time = 300
PHP session.auto_start option	must be disabled	In php.ini: session.auto_start = 0
Database support	One of: MySQL, Oracle, PostgreSQL, IBM DB2	One of the following modules must be installed: mysql, oci8, pgsql, ibm_db2
bcmath		php-bcmath
mbstring		php-mbstring
PHP mbstring.func_overload option	must be disabled	In php.ini: mbstring.func_overload = 0
PHP always_populate_raw_post_data option	must be disabled	Required only for PHP versions 5.6.0 or newer. In php.ini: always_populate_raw_post_data = -1
sockets		php-net-socket. Required for user script support.
gd	2.0 or higher	php-gd. PHP GD extension must support PNG images (--with-png-dir), JPEG (--with-jpeg-dir) images and FreeType 2 (--with-freetype-dir).
libxml	2.6.15	php-xml or php5-dom
xmlwriter		php-xmlwriter
xmlreader		php-xmlreader
ctype		php-ctype
session		php-session
gettext		php-gettext Since Zabbix 2.2.1, the PHP gettext extension is not a mandatory requirement for installing Zabbix. If gettext is not installed, the frontend will work as usual, however, the translations will not be available.

下面開始安裝zabbix4.0

軟件包下載地址：https://www.zabbix.com/download_sources

解壓軟件包：

yum install -y net-snmp-devel
tar zxf zabbix-4.0.0.tar.gz
cd zabbix-4.0.0
./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-libxml2

在這裏有可能會發生報錯：

現象1：

configure: error: Not found mysqlclient library

解決：將編譯時的--with-mysql後面跟上數據庫的安裝路徑

1 make && make install

到這裏安裝成功，下面開始配置各項配置文件

1 vim /usr/local/zabbix/etc/zabbix_server.conf
2 DBHost=localhost #默認註釋掉了，直接取消註釋即可
3 DBName=zabbix #數據庫名字
4 DBUser=zabbix #默認是root，我們授權的用戶是zabbix
5 DBPassword=zabbix #密碼我們授權的也是zabbix

下面是數據庫的導入與授權操作

1.先登錄數據庫

在這裏也許你會不知道數據庫該怎麼登錄，因爲你並不知道數據庫密碼

初始密碼獲取方法： cat /usr/local/mysql/log/mysql.err | grep password

黃色框裏面的就是數據庫的初始密碼了

登錄數據庫以後必須更改初密碼，否則無法進行建庫等操作

更改密碼：

1 use mysql;
2 update user set password=password('mysql') where user='root';
3 flush privileges;
4 create database zabbix;
5 grant all on zabbix.* to zabbix@'localhost' identified by 'zabbixmysql';
6 flush privileges;

接下來是導入數據庫：

1 cd /usr/src/zabbix-4.0.0
2 mysql -uzabbix -pzabbixmysql zabbix < database/mysql/schema.sql
3 mysql -uzabbix -pzabbixmysql zabbix < database/mysql/images.sql
4 mysql -uzabbix -pzabbixmysql zabbix < database/mysql/data.sql

下面我們可以寫一個數據庫連通性的測試頁面放到nginx的html目錄下：

1 vim /usr/local/nginx/html/mysqltest.php

1 <?php
2 $link=mysql_connect('localhost','zabbix','zabbix');
3 if($link) echo "<h1>The database connection was successful!</h1>";
4 else echo "<h1>The database connection was Fail!!</h1>";
5 mysql_close();
6 ?>

瀏覽器訪問nginx的IP後面加上測試文件文件名出先下面內容則代表連接成功：

接下來就是進入zabbix的web界面了，這時候需要把前端文件copy到nginx的HTML目錄下

1 mkdir /usr/local/nginx/html/zabbix
2 cd /usr/src/zabbix-4.0.0/frontends/php/
3 cp * /usr/local/nginx/html/zabbix/

進入web界面：http://ip/zabbix/

下面是安裝過程遇到的問題

提示不滿足zabbix的先決條件

根據提示去更改php.ini的相關數值，參考上面的先決條件

在這個過程可能會涉及到php模塊的安裝，可以參考php擴展模塊的安裝方法安裝就能完成
