Zabbix二：在nginx上搭建
-----------LNMP+Zabbix----------------------------
##兩臺服務器防火墻關閉
[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.
===========LNMP安裝環境（安裝nginx1.14）========
##手動配置yum倉庫
[root@cacti ~]# vim /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
-------------------安裝nginx------------------
[root@cacti ~]# yum list
[root@cacti ~]# yum install nginx -y
[root@cacti ~]# netstat -ntap | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 45100/nginx: master
[root@cacti ~]# systemctl enable nginx
------------------安裝mariadb-----------------
[root@cacti ~]# yum install mariadb-server mariadb -y
[root@cacti ~]# systemctl enable mariadb.service
##設置數據庫
[root@cacti ~]# mysql_secure_installation
回車
y
abc123 ##密碼自己定義
abc123
n
n
n
y
##登錄數據庫
[root@cacti ~]# mysql -uroot -p
Enter password: ##輸入密碼
MariaDB [(none)]>
-----------------安裝php7.2------------------------
#安裝epel源
[root@cacti ~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
##或者
[root@cacti ~]# yum install epel-release -y
[root@cacti ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
[root@cacti ~]# yum install php72w php72w-devel php72w-fpm php72w-gd php72w-mbstring php72w-mysql -y
[root@cacti ~]# php -v
PHP 7.2.10 (cli) (built: Sep 15 2018 07:10:58) ( NTS )
[root@cacti ~]# vim /etc/php-fpm.d/www.conf
user = nginx ##8行
group = nginx ##10行
[root@cacti ~]# vim /etc/php.ini
expose_php = Off ##359行（隱藏php版本）
short_open_tag = On ##202行（支持php短標簽）
##以下為Zabbix配置要求
max_execution_time = 300 ##368行（執行時間）
max_input_time = 300 ##378行（接收數據等待時間）
memory_limit = 128M ##389行（每個腳本占用內存）
post_max_size = 16M ##656行（POST數據大小）
upload_max_filesize = 2M ##799行（下載文件大小）
always_populate_raw_post_data = -1 ##800行
date.timezone = Asia/Shanghai ##877行（時區）
[root@cacti ~]# vim /etc/nginx/conf.d/default.conf
index index.php index.html index.htm; ##10行
location ~ .php$ { ##30-36行（去掉註釋）
root /usr/share/nginx/html; #修改路徑
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /document_root$fastcgi_script_name; #修改用戶root
include fastcgi_params;
}
##啟動服務
[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
##測試
[root@cacti ~]# cd /usr/share/nginx/html/
[root@cacti html]# ls
50x.html index.html
[root@cacti html]# vim info.php
<?php
phpinfo();
?>
http：//192.168.120.183/info.php
##測試連接數據庫
<?php
$link=mysqli_connect(‘127.0.0.1‘,‘root‘,‘abc123‘);
if ($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用戶登錄失敗，參考以下方法
-------------解決本地無法登錄問題（可忽略）---------------------------
[root@cacti html]# mysql -uzabbix -p
Enter password:
ERROR 1045 (28000): Access denied for user ‘zabbix‘@‘localhost‘ (using password: YES)
##出錯##
##解決方案：
##進入root用戶數據庫
[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 |
+--------+-----------+
##出現空用戶，刪除空用戶
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 |
+--------+-----------+
##空用戶已刪除
[root@cacti html]# mysql -uzabbix -p
Enter password:
MariaDB [(none)]>
##登錄成功
----------------以下開始部署zabbix Server-------
