cd mysql-5.5.10

#开始编译并安装

/usr/local/bin/cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/webserver/mysql/ -DMYSQL_DATADIR=/usr/local/webserver/mysql/data -DWITH_INNOBASE_STORAGE_ENGINE=1 -DMYSQL_TCP_PORT=3306 -DMYSQL_UNIX_ADDR=/usr/local/webserver/mysql/data/mysql.sock -DMYSQL_USER=mysql -DWITH_DEBUG=0

make && make install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cp support-files/my-small.cnf /etc/my.cnf
chown mysql:mysql /etc/my.cnf

执行下面的
/usr/local/webserver/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/webserver/mysql --datadir=/usr/local/webserver/mysql/data

在/etc/my.cnf  打开下面的InnoDB配置以减少内存即可：
default-storage-engine=MyISAM
server-id       = 1
innodb_buffer_pool_size = 21M
innodb_additional_mem_pool_size = 2M
innodb_log_file_size = 5M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50

/usr/local/webserver/mysql/bin/mysqld_safe --user=mysql
