CentOS6.5二进制文件安装MySQL5.6.39
准备工作
MySQ二进制安装Lmysql-5.6.39-linux-glibc2.12-x86_64.tar.gz 准备( 官网下载 )
一、检查是否安装过MySQL并卸载
# 检查是否安装过MySQL
[root@csxf ~]# rpm -qa|grep mysql
# 删除所有MySQL
[root@csxf ~]# yum -y remove mysql*
二、上传镜像文件至：/usr/local，解压，移动
[root@csxf ~]# su - root
[root@csxf ~]# cd /usr/local/
[root@csxf local]# tar -xzvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@csxf local]# mv mysql-5.6.39-linux-glibc2.12-x86_64/ mysql
三、添加MySQL用户和组赋予权限
#添加mysql用户和组
[root@csxf ~]# groupadd -g 101 dba
[root@csxf ~]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@csxf ~]# id mysqladmin
#添加环境变量
[root@csxf local]# cp /etc/skel/.* /usr/local/mysql
四、配置my.cnf及修改权限
