在LNMP架构中创建Zabbix监控服务

ASP站长网在上文中我具体操作了在LAMP架构中搭建Zabbix监控服务，在本篇中我将在LNMP中搭建一个Zabbix服务，操作步骤相比于之前要稍微复杂一些，但也只是在细节上LNMP稍多一些，大体过程还是类似的。

操作步骤
一、搭建LNMP
1 安装nginx1.4
 
[root@promote~]#wget http://nginx.org/packages/CentOS/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
[root@promote ~]# rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm    #安装nginx官方源
[root@promote ~]# yum install nginx -y
[root@promote ~]# systemctl start nginx
[root@promote ~]# systemctl enable nginx
[root@promote ~]# netstat -ntap | grep 80
tcp        0      0 0.0.0.0:80              0.0.0.0:*              LISTEN      3024/nginx: master

2 安装mysql5.7（这里为了安装方便我也mariadb来代替mysql，功能都是一样的）：
 
[root@promote ~]# yum install mariadb-server mariadb -y    #下载mariadb安装包
[root@promote ~]# systemctl start mariadb.service
[root@promote ~]# systemctl enable mariadb.service
[root@promote ~]# mysql_secure_installation      #配置mariadb相关参数
Set root password? [Y/n] y
Remove anonymous users? [Y/n] n
Disallow root login remotely? [Y/n] n
Remove test database and access to it? [Y/n] n
Reload privilege tables now? [Y/n] y
 
3 安装PHP7.2
 
[root@promote~]#rpm -Uvh https://dl.Fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@promote ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm    #下载PHPyum源
[root@promote ~]# yum install php72w php72w-devel php72w-fpm php72w-gd php72w-mbstring php72w-mysql -y    #安装PHP相关服务
[root@promote ~]# php -v    #查看版本
PHP 7.2.10 (cli) (built: Sep 15 2018 07:10:58) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
 
4 配置nginx支持PHP：
 
[root@promote ~]# vim /etc/php-fpm.d/www.conf
8 user = nginx    #将Apache改为nginx
10 group = nginx  #将Apache改为nginx
 
5 配置PHP：
 
[root@promote ~]# vim /etc/php.ini
359 expose_php = Off    #隐藏PHP版本
368 max_execution_time = 300    #监控执行时间
378 max_input_time = 300    #接收数据等待时间
389 memory_limit = 128M    #每个脚本占用内存
656 post_max_size = 16M    #POST数据大小
799 upload_max_filesize = 2M    #下载文件大小
800 always_populate_raw_post_data = -1    #可以用$HTTP_RAW_POST_DATA接收post raw data
date.timezone = Asia/Shanghai    #将时区设为上海时区
 
6 配置PHP请求被传送到后端的php-fpm模块，默认情况下php配置模块是被注释掉的:
 
[root@promote ~]# vim /etc/nginx/conf.d/default.conf
10        index  index.php index.html index.htm;
30    location ~ \.php$ {
31        root          /usr/share/nginx/html;
32        fastcgi_pass  127.0.0.1:9000;
33        fastcgi_index  index.php; 34        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_scr    ipt_name; 35        include        fastcgi_params; 36    }    #把fastcgi_param中的/scripts改为$document_root，root是配置php程序用户
 
7 开启服务
 
[root@promote ~]# systemctl start php-fpm.service
[root@promote ~]# systemctl enable php-fpm.service
[root@promote ~]# systemctl restart nginx
[root@promote ~]# vim /usr/share/nginx/html/index.php    #创建PHP测试首页
<?php
  phpinfo();
?>

测试PHP能否连接数据库：
 
[root@promote html]# vim index.php
<?php
$link=mysqli_connect('127.0.0.1','root','123123');
 if ($link) echo "true";
 else echo "false";
?>

8 创建zabbix数据库与zabbix用户：
 
[root@promote html]# mysql -u root -p
MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;
MariaDB [(none)]> grant all privileges on *.* to 'zabbix'@'%' identified by '123123';
MariaDB [(none)]> flush privileges;
 
解决本地无法登陆问题：
 
[root@promote ~]# mysql -u zabbix -p    #现在用zabbix用户是无法登陆数据库的，因为有空用户在进行占用
Enter password:
ERROR 1045 (28000): Access denied for user 'zabbix'@'localhost' (using password: YES)
 
MariaDB [(none)]> select user,host from mysql.user;
+--------+-------------------------+
| user  | host                    |
+--------+-------------------------+
| zabbix | %                      |
| root  | 127.0.0.1              |
| root  | ::1                    |
|        | localhost              |
| root  | localhost              |
|        | promote.cache-dns.local |
| root  | promote.cache-dns.local |
+--------+-------------------------+
7 rows in set (0.00 sec)
 
MariaDB [(none)]> drop user ''@'localhost';    #删除库中的空用户
Query OK, 0 rows affected (0.00 sec)
 
MariaDB [(none)]> drop user ''@'promote.cache-dns.local';    #删除空用户
Query OK, 0 rows affected (0.00 sec)
 
测试zabbix用户能否连接PHP：
 
[root@promote ~]# vim /usr/share/nginx/html/index.php
<?php
$link=mysqli_connect('127.0.0.1','zabbix','123123');
 if ($link) echo "true";
 else echo "false";
?>
