说明：
忘记从哪个版本开始，mysql开始采用cmake进行编译安装，所以在安装MySQL之前我们首先要把Cmake装在我们的系统。
实现：
1. 安装cmake依赖包
# yum -y install ntp vim-enhanced gcc gcc-c++ flex bison autoconf automake bzip2-devel ncurses-devel zlib-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel libXpm-devel gettext-devel pam-devel libtool libtool-ltdl openssl openssl-devel fontconfig-devel libxml2-devel curl-devel libicu libicu-devel libmcrypt libmcrypt-devel libmhash libmhash-devel
2. 下载Cmake的源码包
# wget http://www.cmake.org/files/v2.8/cmake-2.8.7.tar.gz # tar zxvf cmake-2.8.7.tar.gz # cd cmake-2.8.7 # ./configure # make && make install
3. 编译安装配置MySQL
3.1 创建用户及所需目录
# mkdir -pv /usr/local/mysql/data // # groupadd mysql //创建mysql用户和mysql组 # useradd -g mysql -s /usr/sbin/nologin mysql
3.2 cmake编译安装
# tar zxvf mysql-5.5.22.tar.gz # cd mysql-5.5.22 # cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_unicode_ci -DWITH_READLINE=1 -DWITH_SSL=system -DWITH_EMBEDDED_SERVER=1 -DENABLED_LOCAL_INFILE=1 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_DEBUG=0 # make && make install
3.3 复制配置文件及设置权限
# cp support-files/my-medium.cnf /etc/my.cnf # chmod +x /usr/local/mysql # chown -R mysql：mysql /usr/local/mysql # chown -R mysql:mysql /usr/local/mysql/data
3.4 配置启动脚本及开机自启动
# cp support-files/mysql.server /etc/init.d/mysqld # chmod +x /etc/init.d/mysqld # chkconfig --add mysqld # chkconfig mysqld on
3.5 修改配置文件,在[mysqld]中添加
# vim /etc/my.cnf datadir = /usr/local/mysql/data log-error = /usr/local/mysql/data/error.log pid-file = /usr/local/mysql/data/mysql.pid user = mysql tmpdir = /tmp
3.6 初始化数据库
# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
3.7 手动启动MySQL
# service mysqld start
4. 测试MySQL是否启动，查看是否有mysql进程，查看是否有mysql端口
# ps -ef | grep mysql # netstat -tnlp | grep 3306
5. 添加mysql的软链接可以使用用户直接使用
# ln -sv /usr/local/mysql/bin/mysql /usr/bin/mysql # ln -sv /usr/local/mysql/bin/mysqladmin /usr/bin/mysqladmin # ln -sv /usr/local/mysql/bin/mysqldump /usr/bin/mysqldump # mysqladmin version //获取MySQL的版本信息测试mysql,mysqladmin,mysqldump命令是否能正常使用

附录1：centos 5.8 编译 mysql 5.5.32时，参数-DWITH_SSL=system报错
在centos 5.8上编译mysql5.5.32，加了-DWITH_SSL=system参数，编译时报错如下，
/usr/local/src/mysql-5.5.32/vio/viossl.c: In function 'ssl_do': /usr/local/src/mysql-5.5.32/vio/viossl.c:175: error: 'SSL_OP_NO_COMPRESSION' undeclared (first use in this function) /usr/local/src/mysql-5.5.32/vio/viossl.c:175: error: (Each undeclared identifier is reported only once /usr/local/src/mysql-5.5.32/vio/viossl.c:175: error: for each function it appears in.) make[2]: *** [vio/CMakeFiles/vio.dir/viossl.c.o] Error 1 make[1]: *** [vio/CMakeFiles/vio.dir/all] Error 2 make: *** [all] Error 2
网上查了一下，应该是openssl的版本太低造成的，在centos6上编译就没有这个问题。官方已经给出了解决的patch，内容如下
