这期内容当中小编将会给大家带来有关linux下安装MySQL-5.6.31采用yum -y install 命令安装的示例分析,文章内容丰富且以专业的角度为大家分析和叙述,阅读完这篇文章希望大家可以有所收获。
1 安装前的准备
系统版本:linux(版本centos6.5 64位系统) 64位操作系统 ;
下载好 MySQL MySQL-5.6.31-1.linux_glibc2.5.x86_64.rpm-bundle.tar
mysql 下载官网:http://dev.mysql.com/downloads/file/?id=463181
2 下载后解压在你自己新建的文件夹:我的放在 mysql 文件夹下
[root@localhost mysql]# tar -ivh MySQL-5.6.31-1.linux_glibc2.5.x86_64.rpm-bundle.tar
3 开始安装
a 检查MySQL及相关RPM包,是否安装,如果有安装,
则移除(rpm –e 名称 或 yum -y remove 名称)
[root@localhost mysql]# rpm -qa |grep -i mysql ## -i是不区分大小写
MySQL-client-5.6.31-1.linux_glibc2.5.x86_64
MySQL-server-5.6.31-1.linux_glibc2.5.x86_64
[root@localhost mysql]# rpm -e MySQL-client-5.6.31-1.linux_glibc2.5.x86_64 ## 两种移除方法都可以
[root@localhost mysql]# rpm -qa |grep -i mysql
MySQL-server-5.6.31-1.linux_glibc2.5.x86_64
[root@localhost mysql]# yum -y remove MySQL-server-5.6.31-1.linux_glibc2.5.x86_64
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Remove Process
Resolving Dependencies
–> Running transaction check
—> Package MySQL-server.x86_64 0:5.6.31-1.linux_glibc2.5 will be erased
–> Finished Dependency Resolution
……..
Removed:
MySQL-server.x86_64 0:5.6.31-1.linux_glibc2.5
Complete!
接下来安装服务端 和客户端:用 yum -y install 方式
1 先查看文件的详细信息
[root@localhost mysql]# ls -l

[root@localhost mysql]#
我们只要安装红色的两个地方即可:
安装服务端:
[root@localhost mysql]# yum -y install MySQL-server-5.6.31-1.linux_glibc2.5.x86_64.rpm
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
…………….
Installed:
MySQL-server.x86_64 0:5.6.31-1.linux_glibc2.5
Complete
安装完毕后启动服务:
[root@localhost mysql]# /etc/init.d/mysql start
Starting MySQL…….. SUCCESS!
(ps:假如你在这边启动服务的时候,出现报错:比如你mysql 是卸载掉后重新安装mysql的话,有可能会报这个错:Starting MySQL………………………………………………………………………………………….. ERROR! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid). 这是你之前卸载的mysql localhost.localdomain.pid 进程没有杀干净,此时你可以先查看你进程号:ps -ef|grep -i mysqld 然后找到进程强制杀死 如下:
[root@localhost mysql]# ps -ef|grep -i mysqld
root 3643 1 0 13:48 pts/0 00:00:00 /bin/sh /usr/bin/mysqld_safe –datadir=/var/lib/mysql –pid-file=/var/lib/mysql/localhost.localdomain.pid
mysql 3756 3643 1 13:48 pts/0 00:00:38 /usr/sbin/mysqld –basedir=/usr –datadir=/var/lib/mysql –plugin-dir=/usr/lib64/mysql/plugin –user=mysql –log-error=/var/lib/mysql/localhost.localdomain.err –pid-file=/var/lib/mysql/localhost.localdomain.pid
root 5023 1 0 14:48 pts/0 00:00:00 /bin/sh /usr/bin/mysqld_safe –datadir=/var/lib/mysql –pid-file=/var/lib/mysql/localhost.localdomain.pid
mysql 5136 5023 6 14:48 pts/0 00:00:04 /usr/sbin/mysqld –basedir=/usr –datadir=/var/lib/mysql –plugin-dir=/usr/lib64/mysql/plugin –user=mysql –log-error=/var/lib/mysql/localhost.localdomain.err –pid-file=/var/lib/mysql/localhost.localdomain.pid
root 5282 2384 0 14:49 pts/0 00:00:00 grep -i mysqld
[root@localhost mysql]# kill -9 3756 ## 5136 3756 的要是杀了没效果5136 的杀掉
[root@localhost mysql]# /etc/init.d/mysql start
Starting MySQL………. SUCCESS!
)
[root@localhost mysql]#
查看 yum 安装后的默认密码:
[root@localhost mysql]# cat /root/.mysql_secret
# The random password set for the root user at Sun Jul 24 12:14:33 2016 (local time): PwEYW3GrS6Yn1kp2
接下来安装客户端
[root@localhost mysql]# yum -y install MySQL-client-5.6.31-1.linux_glibc2.5.x86_64.rpm
Loaded plugins: fastestmirror, refresh-packagekit, security
………………….
Installed:
MySQL-client.x86_64 0:5.6.31-1.linux_glibc2.5
Complete!
[root@localhost mysql]# rpm -qa |grep -i mysql
MySQL-client-5.6.31-1.linux_glibc2.5.x86_64
MySQL-server-5.6.31-1.linux_glibc2.5.x86_64
[root@localhost mysql]#
此时 可以看到服务端客户端都安装好了,现在开始登陆
这边登陆之前说明下,如果你是之前下已经安装过mysql ,并且是修改过随机密码 :PwEYW3GrS6Yn1kp2(每个人的随机密码不一样哈) 然后再重新安装的话 ,你这时候再cat /root/.mysql_secret 虽然还会是 PwEYW3GrS6Yn1kp2 这个,但是这时候,我们登陆mysql:
mysql -uroot -hlocalhost -p
[root@localhost ~]# mysql -uroot -hlocalhost -p
Enter password:
ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES)
[root@localhost ~]#
会出现这个错误,就是登陆不了,因为这时候密码不是这个了,而是你之前修改的过得密码,我这边还不知道是什么原因,总之我用卸载之前用的密码重新登陆,就登陆成功了:
[root@localhost ~]# mysql -uroot -hlocalhost -p
Enter password:

mysql>
可能是有些地方没有完全卸载干净吧,导致记录了之前的用户信息。这个以后再查证
假如你是之前这个系统重来还没安装过 mysql ,那么你登陆后,输入随机密码,就会登陆成功,成功查看数据库
mysql> show databases;
ERROR 1820 (HY000): You must SET PASSWORD before executing this statement
mysql> set password=password(‘123456’);
Query OK, 0 rows affected (0.00 sec)
