zabbix4.0的安装与配置

#安装zabbix监控首先的先安装LNMP环境，在这里我采用事先准备好的脚本进行安装LNMP环境 脚本内容如下：

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

以上为lnmp环境的搭建，不要准备包，全部在线下载，整个过程最多30分钟，这个只是基本的lnmp环境

如果说要安装zabbix4.0的话还需要满足他的先决条件，在这里我们一步步的来，遇到阻挡了再去安装。

zabbix4.0的先决条件先贴出来

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.

下面开始安装zabbix4.0

软件包下载地址：https://www.zabbix.com/download_sources

解压软件包：

yum install -y net-snmp-devel

 tar zxf zabbix-4.0..tar.gz
 cd zabbix-4.0.
 ./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-libxml2

在这里有可能会发生报错：

现象1：

configure: error: Not found mysqlclient library

解决：将编译时的--with-mysql后面跟上数据库的安装路径

 make && make install

接下来是配置的修改

 cd /usr/src/zabbix-4.0./misc/init.d/
 cp fedora/core/zabbix_server /etc/init.d/
 cp fedora/core/zabbix_agentd /etc/init.d/
 vim /etc/init.d/zabbix_server
 BASEDIR=/usr/local/zabbix  #找到此行，并修改
 vim /etc/init.d/zabbix_agentd
 BASEDIR=/usr/local/zabbix  #找到此行，并修改

到这里安装成功，下面开始配置各项配置文件

 vim /usr/local/zabbix/etc/zabbix_server.conf
 DBHost=localhost #默认注释掉了，直接取消注释即可
 DBName=zabbix #数据库名字
 DBUser=zabbix #默认是root，我们授权的用户是zabbix
 DBPassword=zabbix #密码我们授权的也是zabbix

下面是数据库的导入与授权操作

1.先登录数据库

在这里也许你会不知道数据库该怎么登录，因为你并不知道数据库密码

初始密码获取方法：

 cat /usr/local/mysql/log/mysql.err | grep password

黄色框里面的就是数据库的初始密码了

登录数据库以后必须更改初密码，否则无法进行建库等操作

更改密码：

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

接下来是导入数据库：

 cd /usr/src/zabbix-4.0.
 mysql -uzabbix -pzabbixmysql zabbix < database/mysql/schema.sql
 mysql -uzabbix -pzabbixmysql zabbix < database/mysql/images.sql
 mysql -uzabbix -pzabbixmysql zabbix < database/mysql/data.sql

下面我们可以写一个数据库连通性的测试页面放到nginx的html目录下：

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

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

浏览器访问nginx的IP后面加上测试文件文件名出先下面内容则代表连接成功：

接下来就是进入zabbix的web界面了，这时候需要把前端文件copy到nginx的HTML目录下

 mkdir /usr/local/nginx/html/zabbix
 cd /usr/src/zabbix-4.0./frontends/php/
 cp * /usr/local/nginx/html/zabbix/

进入web界面：http://ip/zabbix/

下面是安装过程遇到的问题

提示不满足zabbix的先决条件

根据提示去更改php.ini的相关数值，参考上面的先决条件

在这个过程可能会涉及到php模块的安装，可以参考php扩展模块的安装方法安装就能完成
