安装mysql5.5时常见错误--缺失make
首先我这是一台centos release 6.2 (final)，新安装的系统，没有任何软件及库文件。安装mysql5.5之前，先需要大概了解一下，需要注意的信息，mysql5.5的安装与其它版本不同的是编译安装时，需要用到cmake，所以做如下操作：
1.yum install gcc* c++ * autoconf automake zlib*  libxml* ncurses-devel libmcrypt* libtool-ltdl-devel*安装系统所需要的库文件
2.安装cmake工具。yum install cmake*
3.由于我这个系统是新安装的没有任何软件，所以如果用yum install cmake*安装成功后，到安装mysql时会出现如下错误，请看：
[root@localhost mysql]# cd mysql-5.5.25a
[root@localhost mysql-5.5.25a]# cmake -dcmake_install_prefix=/usr/local/mysql -dmysql_unix_addr=/data/mysql/mysql.sock -ddefault_charset=utf8 -ddefault_collation=utf8_general_ci -dwith_extra_charsets:string=utf8,gbk -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 -dmysql_tcp_port=3306
cmake error: cmake was unable to find a build program corresponding to unix makefiles.  cmake_make_program is not set.  you probably need to select a different build tool.

大概的意思就是说cmake没有安装好，我明明用yum install cmake*安装好了呀？后来yum install make 后，[root@localhost mysql-5.5.25a]# yum install make
