mysql服务器安装在linux居多，网上有很多种方法，本人推荐用用二进制。理由如下：
1，二进制安装安装方便。
2，oralce制定的在二进制包优化方面也是很优秀的，而大多数dba对GCC编译了解也不是很深，编译源码并不一定会比二进制好。
3，二进制有一定的对比性方便排查问题，源码添加的模块不同不好参考。
=================二进制安装mysql
系统：CentOS 6 x86_64
下载MySQL
mkdir /soft
cd /soft && wget
解压MySQL
tar xf mysql-5.6.29-linux-glibc2.5-x86_64.tar.gz -C /opt
软链接到/usr/local
ln -s /opt/mysql-5.6.29-linux-glibc2.5-x86_64 /usr/local/mysql
创建mysql用户
groupadd mysql && useradd -g mysql -M -s /sbin/nologin mysql
创建必要目录(参考my.cnf)
mkdir -p /log/mysql/{bin_log,relay_log} && chown mysql.mysql -R /log/mysql/
mkdir -p /data/mysql/{tmp,data3306} && chown mysql.mysql -R /data/mysql
修改环境变量
echo "PATH=$PATH:/usr/local/mysql/bin">>/etc/profile && . /etc/profile
编辑my.cnf配置文件虚拟机配置
vi /etc/my.cnf

#=============================================
初始化
cd /usr/local/mysql && ./scripts/mysql_install_db
路径要这么写，此处看到两个OK表示初始化成功
配置启动脚本
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
启动
/etc/init.d/mysqld start
安全加固
/usr/local/mysql/bin/mysqladmin -u root password ‘e10adc3949ba59abbe56e057f20f883e‘
/usr/local/mysql/bin/mysql -uroot -p‘e10adc3949ba59abbe56e057f20f883e‘ -e "delete from mysql.user where password=‘‘;"
/usr/local/mysql/bin/mysql -uroot -p‘e10adc3949ba59abbe56e057f20f883e‘ -e "flush privileges;"
mysql> truncate table mysql.db;
mysql> drop database test;
mysql> flush privileges;
总结：目录规划也很重要，本人是将日志和数据文件完全分开的。本文出自 “11767337” 博客，请务必保留此出处http://11777337.blog.51cto.com/11767337/1792599
