1.解压及创建目录
1.1 解压mysql压缩包并将其重命名为mysql
[root@hadoop001 local]# tar -xzvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
[root@hadoop001 local]# mv mysql-5.7.11-linux-glibc2.5-x86_64 mysql
1.2 在mysql目录下创建arch（归档）、data、tmp文件夹
[root@hadoop001 local]# mkdir mysql/arch mysql/data mysql/tmp
2.创建my.cnf文件（按如下配置）
[root@hadoop001 local]# vi /etc/my.cnf
[client]
port = 3306
socket = /usr/local/mysql/data/mysql.sock
default-character-set=utf8mb4

3.创建用户组及用户
[root@hadoop001 local]# groupadd -g 101 dba
[root@hadoop001 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@hadoop001 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
##if user mysqladmin is existing,please execute the following command of usermod.
#[root@hadoop001 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
4.copy环境变量的配置文件/etc/skel/.*到/usr/local/mysql/中，目的是为了配置个人环境变量如下：
[root@hadoop001 local]# vi mysql/.bashrc
# .bashrc
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
export MYSQL_BASE=/usr/local/mysql
export PATH=${MYSQL_BASE}/bin:$PATH
unset USERNAME
#stty erase ^H
set umask to 022
umask 022
PS1=`uname -n`":"'$USER'":"'$PWD'":>"; export PS1
## end
5.赋权限给用户组，切换用户及安装
[root@hadoop001 local]# chown mysqladmin:dba /etc/my.cnf
[root@hadoop001 local]# chmod 640 /etc/my.cnf
[root@hadoop001 local]# chown -R mysqladmin:dba /usr/local/mysql
[root@hadoop001 local]# chmod -R 755 /usr/local/mysql
6.安装libaio及安装mysql的初始db
[root@hadoop001 local]# yum -y install libaio
[root@hadoop001 local]# sudo su - mysqladmin
hadoop001:mysqladmin:/usr/local/mysql:> bin/mysqld \
> --defaults-file=/etc/my.cnf \
> --user=mysqladmin \
> --basedir=/usr/local/mysql/ \
> --datadir=/usr/local/mysql/data \
> --initialize
在初始化时如果加上 –initial-insecure，则会创建空密码的 root@localhost 账号，否则会创建带密码的 root@localhost 账号，密码直接写在 log-error 日志文件中
（在5.6版本中是放在 ~/.mysql_secret 文件里，更加隐蔽，不熟悉的话可能会无所适从）
7.查看临时密码
hadoop001:mysqladmin:/usr/local/mysql/data:>cat hostname.err |grep password
2017-07-22T02:15:29.439671Z 1 [Note] A temporary password is generated for root@localhost: qw/5O;Ekwdweo
hadoop001:mysqladmin:/usr/local/mysql/data:>
8.启动
hadoop001:mysqladmin:/usr/local/mysql/data:>
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
这种启动方式较为麻烦，下面介绍一个以service启动的方式，需要做如下配置
9.配置服务及开机自启动
[root@hadoop001 local]# cd /usr/local/mysql
#将服务文件拷贝到init.d下，并重命名为mysql
[root@hadoop001 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
#赋予可执行权限
[root@hadoop001 mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[root@hadoop001 mysql]# chkconfig --del mysql
#添加服务
[root@hadoop001 mysql]# chkconfig --add mysql
[root@hadoop001 mysql]# chkconfig --level 345 mysql on
[root@hadoop001 mysql]# vi /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
su - mysqladmin -c "/etc/init.d/mysql start --federated"
"/etc/rc.local" 9L, 278C written
9.启动
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
10.登录及修改用户密码
hadoop39.ruoze:mysqladmin:/usr/local/mysql/data:>mysql -uroot -p'qw/5O;Ekwdweo'
mysql: [Warning] Using a password on the command line interface can be insecure.

Bye
11.重启
hadoop39.ruoze:mysqladmin:/usr/local/mysql:> service mysql restar
hadoop39.ruoze:mysqladmin:/usr/local/mysql/data:>mysql -uroot -pruozedata

12.设置开机自启动
`
[root@hadoop001~]# chkconfig --add mysql
[root@hadoop001~]# chkconfig mysql on
[root@hadoop001~]# chkconfig --level 2345 mysql on
[root@hadoop001~]# chkconfig --list
