源码安装mysql，按文档执行一遍

下载源码包

tar zxf 进入目录

./configure --prefix=/usr/local/mysql --enable-assembler &&make && make install

创建mysql用户，chown -R mysql.mysql /usr/local/mysql/

然后数据库初始化

/usr/local/mysql/bin/mysql_install_db --user=mysql  --datadir=./var --basedir=/usr/local/mysql/

重新

然后启动

/usr/local/mysql/bin/mysqld_safe --user=mysql&

配置源码mysql为系统服务：

cp /usr/local/mysql/share/mysql/my-medium.cnf /etc/my.cnf

cp /usr/local/mysql/share/mysql/mysql.server /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

chkconfig --level 35 mysqld on

service mysqld restart

mysql5.5

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql55/  \

-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \

-DMYSQL_DATADIR=/data/mysql \

-DDEFAULT_COLLATION=utf8_general_ci \

make && make install

创建mysql用户，chown -R mysql.mysql /usr/local/mysql/

/usr/local/mysql/scripts/mysql_install_db --user=mysql  --datadir=./var --basedir=/usr/local/mysql/

这一步初始化数据库系统，初始化数据目录和根目录

nohup /usr/local/mysql55/bin/mysqld_safe --user=mysql & 服务器后台启动mysql

ps -ef |grep mysql 看看开成功没

还不行，要把主机名写在hosts文件里，保证主机名能ping通

然后就可以mysql了

mysql编译安装
