mysql5.6 二进制安装

1. 解压mysql软件包

tar zxvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz -C /usr/local

cd /usr/local
mv mysql-5.6.23-linux-glibc2.5-x86_64/ mysql

2. 新建mysql 管理用户

groupadd -g 101 dba
useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

cp /etc/skel/.* /usr/local/mysql

3. 编辑mysql配置文件
   vi /etc/my.cnf

[client]
port = 3306
socket = /usr/local/mysql/data/mysql.sock

[mysqld]
port = 3306
socket = /usr/local/mysql/data/mysql.sock

4. 根据配置文件 进行权限的修改

chown mysqladmin:dba /etc/my.cnf
chmod 640 /etc/my.cnf
mkdir /usr/local/mysql/arch
chown -R mysqladmin:dba /usr/local/mysql
chmod -R 755 /usr/local/mysql

5. 切换用户进行安装
   su - mysqladmin

初始化数据库：
scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysqladmin

6. 添加环境变量 （root 用户执行）

vi /etc/profile.d/mysql.sh

export PATH=$PATH:/usr/local/mysql/bin

7. 配置开机自启动
   cp support-files/mysql.server /etc/init.d/mysqld
   chmod 755 /etc/init.d/mysqld
   chkconfig mysqld

8. 启动数据库并修改密码（mysqladmin)
   mysqld_safe --defaults-file=/etc/my.cnf &
   /usr/local/mysql/bin/mysqladmin -u root password ‘123’

9. 服务端测试登录
   mysql -uroot -p123
