准备rpm包
yum install -y gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel*
安装cmake
官网下载cmake，为绿色软件，添加环境变量后：
[root@ycr ~]# which cmake
/u02/cmake-3.6.1-Linux-x86_64/bin/cmake
安装boost
下载后解压，进入解压目录后运行
./booststrap之后运行./b2此过程耗时
安装ncurses-5.9.tar.gz
./configure
make
make install

解压安装包mysql-5.5.50
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/tmp/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=/var/mysql/data \
-DMYSQL_USER=mysql

运行完成后make和make install
chmod +w /usr/local/mysql 
chown -R mysql:mysql /usr/local/mysql
ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18
cp my-large.cnf /etc/my.cnf 
cp mysql.server /etc/init.d/mysqld
 
vi /etc/my.cnf添加如下行
basedir = /usr/local/mysql    
datadir = /usr/local/mysql     此处应该和下面的统一，不然会启动报错
log-error = /usr/local/mysql-5.5.14/mysql_error.log
pid-file = /usr/local/mysql-5.5.14/data/mysql.pid
default-storage-engine=MyISAM
user = mysql

mysql初始化，执行如下命令
/usr/local/mysql/scripts/mysql_install_db \
--basedir=/usr/local/mysql \        此处应该和上面的统一，不然启动报错
--datadir=/var/mysql/data \
--user=mysql

加入开机启动mysql
chmod +x /etc/init.d/mysqld 
vi /etc/init.d/mysqld添加如下行
basedir=/usr/local/mysql
datadir=/var/mysql/data

chkconfig --add mysqld 
chkconfig --level 345 mysqld on

为MySQL配置环境变量，以后使用起来方便 
# export PATH=/usr/local/mysql/bin:$PATH
启动mysql
service mysqld start
