Mysql安装编译
一 cmake-3.0.2编译
yum install gcc-c++
yum install ncurses-devel
tar xf cmake-3.0.2.tar.gz
cd cmake-3.0.2
./configure --prefix=/usr/local/cmake3.0.2 && make && make install
vi /etc/profile // 修改环境变量
#在文件末尾追加以下两行代码：
PATH=/usr/local/cmake3.0.2/bin:$PATH
export PATH
source /etc/profile //使修改生效
echo $PATH //查看PATH值
cmake --version //查看是否安装成功
二 jemalloc-3.6.0编译
yum install gcc gcc-c++ cmake ncurses-devel bison
tar xf jemalloc-3.6.0.tar.bz2
cd jemalloc-3.6.0
./configure
make
make install
echo ‘/usr/local/lib‘ > /etc/ld.so.conf.d/local.conf
ldconfig
三 mysql5.6.21编译
useradd -M -s /sbin/nologin mysql
mkdir -p /mysql/data
chown mysql.mysql -R /mysql/data
tar xf mysql-5.6.21.tar.gz
cd mysql-5.6.21
make clean

五、初始化和安全性
初始化数据库：
/mysql/mysql/scripts/mysql_install_db --user=mysql --basedir=/mysql/mysql --datadir=/mysql/data
除去隐患：
grant all privileges on *.* to [email protected]‘127.0.0.1‘ identified by "123456" with grant option;
grant all privileges on *.* to [email protected]‘localhost‘ identified by "123456" with grant option;
delete from mysql.user where Password=‘‘;
delete from mysql.db where User=‘‘;
delete from mysql.proxies_priv where Host!=‘localhost‘;
drop database test;
reset master;
#删除所有index file 中记录的所有binlog 文件，将日志索引文件清空，创建一个新的日志文件，这个命令通常仅仅用于第一次用于搭建主从关系的时的主库，
最后一步：
export PATH=/mysql/mysql/bin:$PATH #增加环境变量
或PATH=/mysql/mysql/bin:$PATH
export PATH
启动mysql，操作试试吧：
mysql -uroot -p
