我这里是RHEL6.5的系统,因此选择RedHat 6 x86,64bit操作系统---下载第一个RPM Bundle即可--mysql-8.0.11-1.el6.x86_64.rpm-bundle.tar。

我这里是RHEL6.5的系统,因此选择RedHat 6 x86,64bit操作系统---下载第一个RPM Bundle即可--mysql-8.0.11-1.el6.x86_64.rpm-bundle.tar。

目前MySQL8.0.11社区版提供了多种多样的安装方式,你也可以通过下载Linux Generic安装包mysql-8.0.11-linux-glibc2.12-x86_64.tar.gz来安装,这种安装方式无需考虑包兼容性,本文只描述rpm安装方式。

目前MySQL8.0.11社区版提供了多种多样的安装方式,但是并未发现针对Linux Generic安装包包含的mysql_secure_installation的安装说明。

一、mysql-8.0.11-1.el6.x86_64.rpm-bundle.tar解压后有如下7个文件:

因此这里使用推荐的RPM安装:

-rw-r--r-- 1 root root  28987588 Apr  9 01:06 mysql-community-client-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root    672184 Apr  9 01:06 mysql-community-common-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root   4443296 Apr  9 01:06 mysql-community-devel-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root   2579460 Apr  9 01:06 mysql-community-libs-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root   1902676 Apr  9 01:06 mysql-community-libs-compat-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 395918848 Apr  9 01:07 mysql-community-server-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root  49092596 Apr  9 01:07 mysql-community-test-8.0.11-1.el6.x86_64.rpm

一、mysql-8.0.11-1.el6.x86_64.rpm-bundle.tar解压后有如下7个文件:

然后创建mysql用户:

-rw-r--r-- 1 root root 28987588 Apr 9 01:06 mysql-community-client-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root  672184 Apr 9 01:06 mysql-community-common-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root  4443296 Apr 9 01:06 mysql-community-devel-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root  2579460 Apr 9 01:06 mysql-community-libs-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root  1902676 Apr 9 01:06 mysql-community-libs-compat-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 395918848 Apr 9 01:07 mysql-community-server-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 49092596 Apr 9 01:07 mysql-community-test-8.0.11-1.el6.x86_64.rpm
useradd mysql
passwd mysql

然后创建mysql用户:

二、安装顺序为:(建议装之前先把之前的mysql相关包全部卸载,rpm -e --nodeps <包名>即可)

useradd mysql
passwd mysql

[root@python ~]# mysql -V
mysql  Ver 8.0.11 for Linux on x86_64 (MySQL Community Server - GPL)
[root@python ~]# ll /etc/init.d/mysqld 
-rwxr-xr-x 1 root root 7166 Apr  8 16:21 /etc/init.d/mysqld
[root@python ~]# ll /etc/my.cnf --配置文件位置
-rw-r--r-- 1 root root 1188 Apr  8 16:21 /etc/my.cnf

三、安装完毕后相关信息如下:

默认的datadir是在/var/lib/mysql/,可以通过修改my.cnf修改,启动命令如下:

[root@python ~]# mysql -V
mysql Ver 8.0.11 for Linux on x86_64 (MySQL Community Server - GPL)
[root@python ~]# ll /etc/init.d/mysqld
-rwxr-xr-x 1 root root 7166 Apr 8 16:21 /etc/init.d/mysqld
[root@python ~]# ll /etc/my.cnf --配置文件位置
-rw-r--r-- 1 root root 1188 Apr 8 16:21 /etc/my.cnf
[root@python ~]# service mysqld start
Initializing MySQL database:                               [  OK  ]
Starting mysqld:                                           [  OK  ]

默认的datadir是在/var/lib/mysql/,可以通过修改my.cnf修改,启动命令如下:

四、发现没密码不能登录,于是添加skip-grant-tables到my.cnf,重启进去重置密码:

[root@python ~]# service mysqld start
Initializing MySQL database:                [ OK ]
Starting mysqld:  
[ OK ]

Ps:20180517新添加:在安装完后,/var/log/mysqld.log里应该含有临时的root密码,可以直接登录,但是依然建议按本文方法修改掉密码认证的策略。 而在Windows平台使用msi安装时,则有自主选择密码认证方式的步骤,可以比较方便的进行设置。

四、发现没密码不能登录,于是添加skip-grant-tables到my.cnf,重启进去重置密码

mysql> alter user root@'localhost' identified by 'mysql';
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
mysql> exit
Bye
mysql> alter user root@'localhost' identified by 'mysql';
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
mysql> exit
Bye

居然不能改。。。于是:

居然不能改。。。于是:

于是设置为0,然后将validate_password.length设置为4,表示最少需要4字符。之所以设置为4是因为这个参数的值不能小于如下公式的计算结果:
