Zabbix二：在nginx上搭建

介绍就不再次介绍了。目前很多公司都在nginx上搭建服务了，所以我又搭建了一个LNMP+Zabbix，具体步骤如下

-----------LNMP+Zabbix----------------------------
##两台服务器防火墙关闭
[root@cacti ~]# systemctl stop firewalld.service
[root@cacti ~]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@cacti ~]# setenforce 0

===========LNMP安装环境（安装nginx1.14）========
##手动配置yum仓库
[root@cacti ~]# vim /etc/yum.repos.d/nginx.repo

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

-------------------安装nginx------------------
[root@cacti ~]# yum list
[root@cacti ~]# yum install nginx -y
[root@cacti ~]# systemctl start nginx
[root@cacti ~]# netstat -ntap | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 45100/nginx: master
[root@cacti ~]# systemctl enable nginx

------------------安装mariadb-----------------
[root@cacti ~]# yum install mariadb-server mariadb -y
[root@cacti ~]# systemctl start mariadb.service
[root@cacti ~]# systemctl enable mariadb.service
##设置数据库
[root@cacti ~]# mysql_secure_installation
回车
y
abc123 ##密码自己定义
abc123
n
n
n
y

##登录数据库
[root@cacti ~]# mysql -uroot -p
Enter password: ##输入密码
MariaDB [(none)]>

-----------------安装php7.2------------------------
#安装epel源
[root@cacti ~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
##或者
[root@cacti ~]# yum install epel-release -y
[root@cacti ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

[root@cacti ~]# yum install php72w php72w-devel php72w-fpm php72w-gd php72w-mbstring php72w-mysql -y
[root@cacti ~]# php -v
PHP 7.2.10 (cli) (built: Sep 15 2018 07:10:58) ( NTS )

[root@cacti ~]# vim /etc/php-fpm.d/www.conf
user = nginx ##8行
group = nginx ##10行

[root@cacti ~]# vim /etc/php.ini
expose_php = Off ##359行（隐藏php版本）
short_open_tag = On ##202行（支持php短标签）

##以下为Zabbix配置要求
max_execution_time = 300 ##368行（执行时间）
max_input_time = 300 ##378行（接收数据等待时间）
memory_limit = 128M ##389行（每个脚本占用内存）
post_max_size = 16M ##656行（POST数据大小）
upload_max_filesize = 2M ##799行（下载文件大小）
always_populate_raw_post_data = -1 ##800行
date.timezone = Asia/Shanghai ##877行（时区）

[root@cacti ~]# vim /etc/nginx/conf.d/default.conf
index index.php index.html index.htm; ##10行
location ~ .php$ { ##30-36行（去掉注释）
root /usr/share/nginx/html; #修改路径
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /document_root$fastcgi_script_name; #修改用户root
include fastcgi_params;
}

##启动服务
[root@cacti ~]# systemctl start php-fpm.service
[root@cacti ~]# systemctl enable php-fpm.service
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.
[root@cacti ~]# netstat -ntap | grep 9000
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 3250/php-fpm: maste
[root@cacti ~]# systemctl restart nginx

##测试
[root@cacti ~]# cd /usr/share/nginx/html/
[root@cacti html]# ls
50x.html index.html
[root@cacti html]# vim info.php

phpinfo();
?>

http：//192.168.120.183/info.php
##测试连接数据库

$link=mysqli_connect('127.0.0.1','root','abc123');
if ($link) echo "true !!!";
else echo "false !!!";
?>

[root@cacti html]# mysql -uroot -p
Enter password:
MariaDB [(none)]> CREATE DATABASE zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.02 sec)

MariaDB [(none)]> GRANT all privileges ON . TO 'zabbix'@'%' IDENTIFIED BY 'admin123';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

[root@cacti html]# mysql -uzabbix -p
Enter password:
MariaDB [(none)]>

##如果zabbix用户登录失败，参考以下方法
-------------解决本地无法登录问题（可忽略）---------------------------
[root@cacti html]# mysql -uzabbix -p
Enter password:
ERROR 1045 (28000): Access denied for user 'zabbix'@'localhost' (using password: YES)
##出错##
##解决方案：
##进入root用户数据库
[root@cacti html]# mysql -uroot -p

MariaDB [(none)]> select user,host from mysql.user;
+--------+-----------+
| user | host |
+--------+-----------+
| zabbix | % |
| root | 127.0.0.1 |
| root | ::1 |
| | cacti |
| root | cacti |
| | localhost |
| root | localhost |
+--------+-----------+
##出现空用户，删除空用户
MariaDB [(none)]> drop user ''@localhost;
Query OK, 0 rows affected (0.02 sec)

MariaDB [(none)]> drop user ''@cacti;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> select user,host from mysql.user;
+--------+-----------+
| user | host |
+--------+-----------+
| zabbix | % |
| root | 127.0.0.1 |
| root | ::1 |
| root | cacti |
| root | localhost |
+--------+-----------+
##空用户已删除

[root@cacti html]# mysql -uzabbix -p
Enter password:
MariaDB [(none)]>
##登录成功
