[root@centos ]#make && make install
--------------------------------------------------------------------------------
修改权限：
[root@centos ]#chown mysql:mysql /etc/my.cnf
[root@centos ]#chown -R mysql:mysql /usr/local/mysql/mysqldir

修改配置文件：
[root@centos ]#vim /etc/my.cnf
序号18 basedir = /usr/local/mysql/mysqldir
19 datadir = /usr/local/mysql/mysqldir/data
20 port = 3306
21 server_id = 1
22 socket = /usr/local/mysql/mysqld.sock

创建系统数据库的表:
[root@centos ]#/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql

添加系统服务
[root@centos ]#cp support-files/mysql.server /etc/init.d/mysqld
[root@centos ]#vim /etc/init.d/mysqld
46 basedir==/usr/local/mysql/mysqldir
47 datadir=/usr/local/mysql/mysqldir/data
[root@centos ]#chkconfig --add mysqld
[root@centos ]#chkconfig mysql on
[root@centos ]#service mysqld start

设置环境变量
[root@centos ]#vim ~/.bash_profile
第10行 PATH=$PATH:$HOME/bin:/usr/local/mysql/mysqldir/bin

登陆mysql:
[root@centos ]#cd /usr/local/mysql/mysqldir/bin
[root@centos ]#./mysqladmin -u root password '123456' //设置root用户密码为123456
[root@centos ]#./mysql -u root -p （提示输入密码后登陆成功）
[root@centos ]#

出错：
CMake Error at cmake/readline.cmake:82 (MESSAGE):
Curses library not found. Please install appropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on RedHat and derivates it is ncurses-devel.
Call Stack (most recent call first):
cmake/readline.cmake:126 (FIND_CURSES)
cmake/readline.cmake:216 (MYSQL_USE_BUNDLED_LIBEDIT)

-- Configuring incomplete, errors occurred!

缺少包：ncurses-devel
解决：
[root@centos ]#yum install ncurses-devel
[root@centos ]#rm -f CMakeCache.txt (前面已安装但仍出问题直接执行这句)

==========================================================================
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock

解决1：mysql -u 你的mysql用户名 -p -S /usr/local/mysql/mysqldir/mysql.sock (my.cnf中socket目录)
解决2：my.cnf中改为socket =/tmp/mysql.sock

mysql>use mysql;
mysql>SELECT `Host`,`User` FROM user;
mysql>UPDATE user SET `Host` = '%' WHERE `User` = 'root' LIMIT 1;
mysql>flush privileges;
