1.解压及创建目录

[root@hadoop39 local]# tar xzvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz

[root@hadoop39 local]# mv mysql-5.7.11-linux-glibc2.5-x86_64 mysql

[root@hadoop39 local]# mkdir mysql/arch mysql/data mysql/tmp2.创建my.cnf(见文件)

[root@hadoop39 local]# vi/etc/my.cnf

[root@hadoop39 local]# groupadd-g 101dba

[root@hadoop39 local]# useradd-u 514 -g dba -G root -d /usr/local/mysql mysqladmin

[root@hadoop39 local]# id mysqladmin

uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)

## 一般不需要设置mysqladmin的密码，直接从root或者LDAP用户sudo切换

#[root@hadoop39 local]# passwd mysqladmin

Changing passwordforuser mysqladmin.

New UNIX password:

BAD PASSWORD: itis too simplistic/systematic

RetypenewUNIX password:

passwd: all authentication tokens updated successfully.

##if user mysqladmin isexisting,please execute the following command of usermod.

#[root@hadoop39 local]# usermod-u 514 -g dba -G root -d /usr/local/mysql mysqladmin4.copy 环境变量配置文件至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量

[root@hadoop39 local]# cp/etc/skel/.* /usr/local/mysql ###important5.配置环境变量

[root@hadoop39 local]# vi mysql/.bash_profile

# .bash_profile

# Get the aliases and functionsif [ -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^Hset umask to 022umask022PS1=`uname -n`":"'$USER'":"'$PWD'":>"; export PS1

## end6.赋权限和用户组，切换用户mysqladmin，安装

[root@hadoop39 local]# chown mysqladmin:dba/etc/my.cnf

[root@hadoop39 local]# chmod640 /etc/my.cnf

[root@hadoop39 local]# chown-R mysqladmin:dba /usr/local/mysql

[root@hadoop39 local]# chmod-R 755 /usr/local/mysql7.配置服务及开机自启动

[root@hadoop39 local]# cd/usr/local/mysql

#将服务文件拷贝到init.d下，并重命名为mysql

[root@hadoop39 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql

#赋予可执行权限

[root@hadoop39 mysql]# chmod+x /etc/rc.d/init.d/mysql

#删除服务

[root@hadoop39 mysql]# chkconfig--del mysql

#添加服务

[root@hadoop39 mysql]# chkconfig--add mysql

[root@hadoop39 mysql]# chkconfig--level 345mysql on8.安装libaio及安装mysql的初始db

[root@hadoop39 mysql]# yum-y install libaio

[root@hadoop39 mysql]# sudo su-mysqladmin

hadoop39.ruoze: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)9.查看临时密码

hadoop39.ruoze:mysqladmin:/usr/local/mysql/data:>cat hostname.err |grep password2017-07-22T02:15:29.439671Z 1 [Note] A temporary password is generated for root@localhost: kFCqrXeh2y(0hadoop39.ruoze:mysqladmin:/usr/local/mysql/data:>

10.启动/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &

11.登录及修改用户密码

hadoop39.ruoze:mysqladmin:/usr/local/mysql/data:>mysql -uroot -p'kFCqrXeh2y(0'mysql: [Warning] Using a password on the command lineinterfacecan be insecure.
