linux 安装完phpadmin后登陆报错：mysqli_real_connect(): (HY000/2002): No such file or directory

解决办法：

1，#查看mysql.sock文件地址
[root@localhost ~]# mysql -uroot -p
Enter password:

2，#修改php.ini文件，参数填入mysql.scok的文件地址
[Pdo_mysql]
······
pdo_mysql.default_socket=/data/mysql/mysql.sock

[MySQLi]
······
mysqli.default_socket = /data/mysql/mysql.sock

重启php-fpm，重新登录

解决两个警告提示：

警告1：phpMyAdmin 高级功能尚未完全设置，部分功能未激活。查找原因。 或者也可以去某个数据库的“操作”选项卡那里进行设置。

#在phpmyadmin的程序目录下面找到sql目录，执行下create_tables.sql
cd phpadmin/sql
mysql -uroot -p -e 'source create_tables.sql'

警告2：配置文件现在需要一个短语密码

#修改程序根目录下config.sample.inc.php文件 和  libraries目录下config.default.php文件
vim config.sample.inc.php
······· 
$cfg['blowfish_secret'] = '1111-1111-1111-1111-1111-1111-1111'; //修改超过32个以上的字符即可

vim libraries/config.default.php
$cfg['blowfish_secret'] = '1111-1111-1111-1111-1111-1111-1111';
