开始安装mysql

把刚刚那两个包全部放入Linux

tar zxf cmake-*.tar.gz

cd cmake-*

./configure

gmake && gmake install

cmake安装好了

groupadd  mysql

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

cd

回到默认目录，和mysql解压包同级目录

tar zxvf mysql-*.tar.gz -C /usr/src/

cd /usr/src/mysql-*

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DSYSCONFDIR=/etc

make && make install

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

rm -rf /etc/my.cnf

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

/usr/local/mysql/scripts/mysql_install_db  --user=mysql  --basedir=/usr/local/mysql  --datadir=/usr/local/mysql/data/

初始化 

echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile

写入环境变量

source /etc/profile

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

写入系统服务 

chmod +x /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

现在就安装好了

现在就正式安装好了 

chkconfig mysqld on

 开启开机自启

chkconfig mysqld off

关闭开机自启

systemctl start mysqld
