phpMyAdmin
1 下載phpMyAdmin-4.0.5-all-languages.zip，並解壓之
[root@husa ~]# ls
99.sh a.sh latest.tar.gz phpMyAdmin-4.0.5-all-languages service.sh wordpress-4.4.1.tar.gz
anaconda-ks.cfg grub.bak linux-3.10.67.tar.xz phpMyAdmin-4.0.5-all-languages.zip show.sh2 複製phpMyAdmin-4.0.5-all-languages目錄至/var/www/html目錄
[root@husa ~]# cp -r phpMyAdmin-4.0.5-all-languages /var/www/html/
[root@husa ~]# ls /var/www/html/
index.php.bak phpMyAdmin-4.0.5-all-languages wordpress3 修改pma配置文件
[root@husa ~]# cd /var/www/html/
[root@husa html]# ln -sv phpMyAdmin-4.0.5-all-languages pma
"pma" -> "phpMyAdmin-4.0.5-all-languages"
[root@husa html]# ls
index.php.bak phpMyAdmin-4.0.5-all-languages pma wordpress
[root@husa ~]# openssl rand -base64 15
u9T2XpvocJvx3NyD/Yj9
[root@husa pma]# pwd
/var/www/html/pma
[root@husa pma]# cp config.sample.inc.php config.inc.php
[root@husa pma]# vim config.inc.php
# 修改下面的這個字段
$cfg['blowfish_secret'] = 'u9T2XpvocJvx3NyD/Yj9'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
4 啓動httpd
[root@husa pma]# systemctl start httpd
[root@husa pma]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 50 *:3306 *:*
LISTEN 0 128 *:22 *:*
LISTEN 0 100 127.0.0.1:25 *:*
LISTEN 0 128 :::80 :::*
LISTEN 0 128 :::22 :::*
LISTEN 0 100 ::1:25 :::* 5 訪問站點發現缺少mbstring(多字節字符串庫)
6 安裝之
[root@husa pma]# yum install php-mbstring7 重啓httpd再次訪問，仍然不能訪問！

8 也就是設置root用戶的密碼：這裏不是答案中的密碼，而是你自己給root設置的密碼，因爲一開始不知道，所以最後又一次的修改了密碼，修改方法如下：即修改mysql.user表中的root用戶的password字段。
MariaDB [(none)]> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [mysql]> update user set password=password('root') where user='root';
Query OK, 4 rows affected (0.05 sec)
Rows matched: 5 Changed: 4 Warnings: 0
MariaDB [mysql]> flush privileges;
Query OK, 0 rows affected (0.00 sec)9 再次連接結果！
出現這種現象的原因是：If you are installing first time then please try login with username and password as root。也就是首次安裝mysql後要以root用戶登錄
