进入MySQL5.5以后，MySQL的安装都变成了用Cmake来安装了。

一：准备工作

cd /usr/local/src/

在当前目录下准备好安装包，

cmake-3.0.2.tar.gz

mysql-5.6.20.tar.gz

二：安装

#cmake

tar -zxvf cmake-3.0.2.tar.gz

cd cmake-3.0.2

./bootstrap

gmake

gmake install

#mysql

tar zxvf mysql-5.6.20.tar.gz

cd mysql-5.6.20

cmake \

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

-DMYSQL_DATADIR=/usr/local/mysql/data \

-DSYSCONFDIR=/etc \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_PARTITION_STORAGE_ENGINE=1 \

-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \

-DMYSQL_TCP_PORT=3306 \

-DENABLED_LOCAL_INFILE=1 \

-DEXTRA_CHARSETS=all \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci

make && make install

#生成配置文件

cd support-files

cp my-default.cnf /etc/my.cnf

groupadd mysql

useradd -M -s /sbin/nologin -g mysql mysql

chown -R mysql:mysql /usr/local/mysql

cd /usr/local/mysql

#初始化数据库

scripts/mysql_install_db --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql

#添加服务，拷贝服务脚本到init.d目录，并设置开机启动

cp support-files/mysql.server /etc/init.d/mysqld

chkconfig mysqld on

#启动MySQL

service mysqld start

#更改密码

/usr/local/mysql/bin/mysqladmin -u root password 123456

#测试连接mysql

/usr/local/mysql/bin/mysql -u root -p

修改/etc/profile文件，在文件末尾添加

vi /etc/profile

PATH=/usr/local/mysql/bin:$PATH

export PATH

source /etc/profile
