phpMyAdmin – ./tmp/ is not accessible

安裝完的 phpMyAdmin 在首頁都會顯示.

The $cfg['TempDir'] (./tmp/) is not accessible. phpMyAdmin is not able to cache templates and will be slow because of this.

無法存取 $cfg['TempDir'] (./tmp/)。phpMyAdmin 會無法快取模版，並且會因為此原因變得很慢。

測試環境為 CentOS 8 x86_64

主要 phpMyAdmin 會使用一個資料夾當作暫存資料的快取,不設定也可以(會影響 phpMyAdmin 效能),照下面的方式來設定.

[root@localhost ~]# cd /var/www/html/phpMyAdmin
[root@localhost phpMyAdmin]# mkdir tmp
[root@localhost phpMyAdmin]# chmod 777 tmp

還需在 config.inc.php 加入以下的設定.

[root@localhost phpMyAdmin]# vi config.inc.php
$cfg['TempDir'] = 'tmp';

請重新登入 phpMyAdmin 以載入新設定並使其生效.

如果還不行請先把 SELinux disable 試試看 (預設為 enforcing ).我們只能調整開機後不要啟動 selinux 功能.所以必須重新開關機.

[root@localhost ~]# vi /etc/sysconfig/selinux 
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
#SELINUX=enforcing
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

[root@localhost ~]# reboot

[root@localhost ~]# sestatus 
SELinux status:                 disabled
