没有网络的服务器要下载那个版本的mysql mysql没网可以安装吗

过程不需要联网
1、下载安装包
http://dev.mysql.com/downloads/mysql/#downloads

2.检查库文件是否存在，如有删除。

[root@localhost Desktop]$ rpm -qa | grep mysql
 mysql-libs-5.1.52-1.el6_0.1.x86_64[root@localhost ~]# rpm -e mysql-libs-5.1.52.x86_64--nodeps
 [root@localhost ~]#

3.检查mysql组和用户是否存在，如无创建。

[root@localhost ~]# cat /etc/group | grep mysql
 mysql:x:490:
 [root@localhost ~]# cat /etc/passwd | grep mysql
 mysql:x:496:490::/home/mysql:/bin/bash

以上为默认存在的情况，如无，执行添加命令：
[root@localhost ~]#groupadd mysql
[root@localhost ~]#useradd -r -g mysql mysql
//useradd -r参数表示mysql用户是系统用户，不可用于登录系统。

4.开始解压,。

[root@localhost ~]# mysql-5.7.21-linux-glibc2.5-x86_64.tar.gz

再解压,得到我们想要的,并解压到/usr/local/apps/

apps是我前面创建的用户存放应用

[root@localhost ~]# tar -zxvf mysql-5.7.21-linux-glibc2.5-x86_64.tar.gz -C  /usr/local/apps/

 

这时在program下得到的目录名很长，如果不想改名，则可以建立一个连接(类似于Windows快捷方式)：

[root@localhost apps]# ln -s mysql-5.7.21-linux-glibc2.5-x86_64 mysql

这么配置后,就可以用/usr/local/apps/mysql来找到mysql的安装目录了

注意，如果mysql目录下没有data目录，手动建一个。用户存放数据

初始化

[root@localhost ~]# /usr/local/apps/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/apps/mysql/data --basedir=/usr/local/apps/mysql

时间可能长了一点,稍微等下.

[root@Ta-GVSM-M-016@00502 apps]# /usr/local/apps/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/apps/mysql/data --basedir=/usr/local/apps/mysql
如果执行完以上代码报如下错：
/usr/local/apps/mysql/bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
请先安装：libaio-0.3.107-10.el6.x86_64.rpm
[root@Ta-GVSM-M-016@00502 ~]# rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm
warning: libaio-0.3.107-10.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]
   1:libaio                 ########################################### [100%]
以上操作表示安装！

再次执行以下操作：
[root@Ta-GVSM-M-016@00502 apps]# /usr/local/apps/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/apps/mysql/data --basedir=/usr/local/apps/mysql
如果执行完报以下操作表示缺少：libnuma.so.1 文件
/usr/local/apps/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory
下载并安装：numactl-2.0.9-2.el6.x86_64.rpm
[root@Ta-GVSM-M-016@00502 ~]# rpm -ivh numactl-2.0.9-2.el6.x86_64.rpm 
warning: numactl-2.0.9-2.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]
   1:numactl                ########################################### [100%]
以上展示说明安装成功！

没有ERROR信息跳过以上操作进入下一步

5、设置mysql以服务运行并且开机启动

将 /usr/local/apps/mysql/support-files/mysql.server 拷贝为/etc/init.d/mysql并设置运行权限

#cp mysql.server /etc/init.d/mysql

#chmod +x /etc/init.d/mysql

 把mysql注册为开机启动的服务

#chkconfig --add mysql

 当然也可以手动进行服务的开启和关闭：

#/etc/init.d/mysql start

#/etc/init.d/mysql stop

【添加本地配置】安装文件夹->本机

将mysql/support-files下的my-default.cnf改名为my.cnf，拷到/etc下      

[root@localhost ~]#cp /usr/local/apps/mysql/support-files/my-default.cnf   /etc/my.cnf

如果不存在my-default.cnf 请直接到/etc/my.cnf下寻找！！！

使用vi打开后编辑(以下仅为基础配置)

将三个都进行简单的配置可以解决不少bug,我前面踩了许多坑

[mysqld]
[mysql]
[client]
# For advice on how to change settings please see
 # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
 # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
 # *** default location during install, and will be replaced if you
 # *** upgrade to a newer version of MySQL.[mysqld]
 character-set-server = utf8
 basedir = /usr/local/apps/mysql
 datadir = /usr/local/apps/mysql/data
 port = 3306
 socket = /usr/local/apps/mysql/tmp/mysql.sock
 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
  [client]
 default-character-set=utf8
 socket=/usr/local/apps/mysql/tmp/mysql.sock[mysql]
 default-character-set=utf8
 socket=/usr/local/apps/mysql/tmp/mysql.sock
 # Remove leading # and set to the amount of RAM for the most important data
 # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
 # innodb_buffer_pool_size = 128M# Remove leading # to turn on a very important data integrity option: logging
 # changes to the binary log between backups.
 # log_bin# These are commonly set, remove the # and set as required.
 # basedir = .....
 # datadir = .....
 # port = .....
 # server_id = .....
 # socket = .....# Remove leading # to set options mainly useful for reporting servers.
 # The server defaults are faster for transactions and fast SELECTs.
 # Adjust sizes as needed, experiment to find the optimal values.
 # join_buffer_size = 128M
 # sort_buffer_size = 2M
 # read_rnd_buffer_size = 2M

此外：socket =/usr/local/apps/mysql/tmp/mysql.sock，这里的tmp文件夹为自行创建

sock文件是用于建立两个程序之间的连接使用的。需要给与mysql用户（上文创建了）权限。

首先mkdirtmp,然后进入/usr/local/apps/mysql目录，修改权限

[root@localhost mysql]# chown -R mysql:mysql tmp

运行

#{mysql}/bin/mysqld_safe&

注：在这个启动脚本里已默认设置--user=mysql；在脚本末尾加&表示设置此进程为后台进程，区别就是在控制台输入bg，即可将当前进程转入后台，当前shell可进行其他操作。

 

客户端连接测试

[root@localhost mysql]# /usr/local/apps/mysql/bin/mysql -uroot -p

我在登陆时时出现了这个错误(密码不正确)：

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

解决方法：

打开my.cnf文件

在[mysqld]下添加这么一行

skip-grant-tables
[mysqld]
character-set-server = utf8
basedir = /usr/local/apps/mysql
datadir = /usr/local/apps/mysql/data
port = 3306
socket = /usr/local/apps/mysql/tmp/mysql.sock
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
skip-grant-tables

跳过密码校验，这样登陆mysql就不需要密码了

然后使用sql语句修改root用户的密码

update mysql.user set authentication_string=password('123456') where user='root' ;

然后，再将skip-grant-tables从my.cnf文件中去掉，即可完成。

重启mysql服务

再次运行

service mysql restart

[root@localhost mysql]# /usr/local/apps/mysql/bin/mysql -uroot -p

就完成了 

最后还有一步,将MySQL加入环境变量

vim /etc/profile
#MySQL
 export MYSQL_HOME=/usr/local/apps/mysql
 export PATH=$PATH:$MYSQL_HOME/bin

添加在里面

然后 source /etc/profile

就可以在任意目录下使用 mysql -root -p 命令了

再授权所有其他主机都可访问

 

mysql>grant all on *.* to root@'%' identified by '123456'; 
mysql>flush privileges;
如果遇到ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement

解决方案:

 

安装完mysql 之后，登陆以后，不管运行任何命令，总是提示这个

step 1: SET PASSWORD = PASSWORD('your new password');

step 2: ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;

step 3: flush privileges;
