编译安装MySQL
1、安装MySQL需要的依赖包和编译软件
（1）安装MySQL需要的依赖包
#yum install ncurses-devel libaio-devel -y
（2）安装编译MySQL需要的软件
#ls -lh cmake-2.8.8.tar.gz
#tar xf cmake-2.8.8.tar.gz
#cd cmake-2.8.8
#./configure
#gmake && gmake install
或者直接yum安装
#yum install cmake -y
2、开始安装MySQL
（1）建立MySQL用户帐号
#useradd -s /sbin/nologin -M mysql
(2)获取MySQL软件包
http://mirrors.sohu.com/
（3）采用编译方式安装MySQL
#tar xf mysql-5.5.49.tar.gz
#cd mysql-5.5.49
cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.49\ -DMYSQL_DATADIR=/application/mysql-5.5.49/data \ -DMYSQL_UNIX_ADDR=/application/mysql-5.5.49/tmp/mysql.sock\ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \ -DENABLED_LOCAL_INFILE=ON \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_FEDERATED_STORAGE_ENGINE=1 \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \ -DWITHOUT_PARTITION_STORAGE_ENGINE=1 \ -DWITH_FAST_MUTEXES=1 \ -DWITH_ZLIB=bundled \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_READLINE=1 \ -DWITH_EMBEDDED_SERVER=1 \ -DWITH_DEBUG=0
#make && make install
