tar zxvf mysql-5.5.9.tar.gz

cd mysql-5.5.9

cmake . \

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ \

-DMYSQL_DATADIR=/var/mysql\

-DMYSQL_UNIX_ADDR=/var/mysql/mysqld.sock \

-DWITH_INNOBASE_STORAGE_ENGINE=1\

-DENABLED_LOCAL_INFILE=1\

-DMYSQL_TCP_PORT=3306\

-DEXTRA_CHARSETS=all \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8-general_ci \

-DMYSQL_UNIX_ADDR=/var/mysql/mysql.sock \

-DWITH_DEBUG=0

报错：

解决：yum install ncurses*

rm CMakeCache.txt

再执行上面命令

cmake . \

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ \

-DMYSQL_DATADIR=/var/mysql\

-DMYSQL_UNIX_ADDR=/var/mysql/mysqld.sock \

-DWITH_INNOBASE_STORAGE_ENGINE=1\

-DENABLED_LOCAL_INFILE=1\

-DMYSQL_TCP_PORT=3306\

-DEXTRA_CHARSETS=all \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8-general_ci \

-DMYSQL_UNIX_ADDR=/var/mysql/mysql.sock \

-DWITH_DEBUG=0

复制配置文件

cp support-files/my-huge.cnf /etc/my.cnf

cp support-files/mysql.server /etc/init.d/mysqld

chmod 755 /etc/init.d/mysqld

/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data &

修改配置文件my.cnf

在[mysqld]下添加　：datadir = /usr/local/mysql/data/

没添加的话数据库无法启动

service mysqld start

设置密码：mysqladmin -uroot password "yourpassword"
