###################################################################################################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
