[root@hadoop-01 ~]# cd /usr/local

61affe944eff55fcf51b31e67f25dc10  mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

检查是否已安装

[root@hadoop-01 local]# ps -ef|grep mysqld

解压重命名

[root@hadoop-01 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

[root@hadoop-01 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql

创建用户组

[root@hadoop-01 local]# groupadd -g 101 dba

[root@hadoop-01 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

[root@hadoop-01 local]# id mysqladmin

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

[root@hadoop-01 local]# passwd mysqladmin

# 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@hadoop-01 local]# cp /etc/skel/.* /usr/local/mysql

创建配置文件 /etc/my.cnf(640)

[root@hadoop-01 mysql]# vi /etc/my.cnf

删除内容，并将以下内容复制进去

指定文件用户组、修改权限、尝试首次安装

[root@hadoop-01 local]# chown  mysqladmin:dba /etc/my.cnf 

[root@hadoop-01 local]# chmod  640 /etc/my.cnf  

[root@hadoop-01 etc]# ll my.cnf

-rw-r----- 1 mysqladmin dba 2201 Aug 25 23:09 my.cnf    

[root@hadoop-01 local]# chown -R mysqladmin:dba /usr/local/mysql

[root@hadoop-01 local]# chmod -R 755 /usr/local/mysql 

[root@hadoop-01 local]# su - mysqladmin

[mysqladmin@hadoop-01 ~]# pwd

/usr/local/mysql

[mysqladmin@hadoop-01 ~]# mkdir arch

[mysqladmin@hadoop-01 ~]# scripts/mysql_install_db ###import

Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory  #缺少libaio.so 包

[root@hadoop-01 local]# yum -y install libaio

再次安装

[mysqladmin@hadoop-01 ~]# scripts/mysql_install_db  --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 

配置mysql服务自启动

[root@sht-sgmhadoopnn-01 ~]# cd /usr/local/mysql

#将服务文件拷贝到init.d下，并重命名为mysql

[root@sht-sgmhadoopnn-01 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql 

#赋予可执行权限

[root@sht-sgmhadoopnn-01 mysql]# chmod +x /etc/rc.d/init.d/mysql

#删除服务

[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql

#添加服务

[root@sht-sgmhadoopnn-01 mysql]# chkconfig --add mysql

[root@sht-sgmhadoopnn-01 mysql]# chkconfig --level 345 mysql on

[root@sht-sgmhadoopnn-01 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"

查看进程

[root@hadoop-01 mysql]# su - mysqladmin

[mysqladmin@hadoop-01 ~]# pwd

/usr/local/mysql

[mysqladmin@hadoop-01 ~]# rm -rf my.cnf

[mysqladmin@hadoop-01 ~]#  bin/mysqld_safe &

[mysqladmin@hadoop-01 ~]# ps -ef|grep mysqld

[mysqladmin@hadoop-01 ~]# netstat -tulnp | grep mysql

[root@hadoop-01 local]# service mysql status

登录mysql

[mysqladmin@hadoop-01 ~]# bin/mysql

mysql> show databases;

+--------------------+

| Database           |

+--------------------+

| information_schema |

| mysql              |

| performance_schema |

| test               |

+--------------------+

修改密码

mysql> use mysql;

mysql> update user set password=password('password') where user='root';

配置环境变量

[mysqladmin@hadoop-01 ~]$ vi ./.bash_profile

# insert

export MYSQL_HOME=/usr/local/mysql

export PATH=${MYSQL_HOME}/bin:$PATH

[mysqladmin@hadoop-01 ~]$ source ./.bash_profile    

[mysqladmin@hadoop-01 ~]$ vi ./.bash_profile

实现window和其他工具远程连接linux服务器

1、登陆mysql数据库    

   mysql -u root -p

   查看user表

mysql> use mysql;

Database changed

mysql> select host,user,password from user;

+--------------+------+-------------------------------------------+

| host         | user | password                                  |
