1:cmake -DCMAKE_INSTALL_PREFIX=/opt/mysql -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS:STRING=all   -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_DATADIR=/data/mysql -DMYSQL_USER=mysql-test/

2:  sudo make && sudo make install

apt-get install php5curl

修改basedir=/usr/local/mysql

         datadir=/var/mysql/data

 

mv mysqld /etc/init.d/mysqld

phpMyAdmin出现#2002 无法登录 MySQL 服务器

 

ln -s /tmp/mysql.sock  /var/lib/mysql/mysql.sock

要将 config.inc.php 中

$cfg['Servers'][$i]['host'] = ’localhost’;
改成 $cfg['Servers'][$i]['host'] = '127.0.0.1';
