mysql5.6 centos7下安装之rpm安装

参考：mysql安装一 rpm包安装

一：下载与解压

下载地址：mysql-5.6-30 密码：mg0r 我放到了 /usr/local/mysql 传输的话可以考虑winscp

创建并解压至mysql目录

mkdir mysql
tar xvf MySQL-5.6.30-1.linux_glibc2.5.x86_64.rpm-bundle.tar -C /usr/local/mysql/

二：安装前的准备

安装MySQL-shared-compat替换mysql-libs，如果不替换，在删除mysql-libs，会提示postfix依赖于mysql-libs：

# rpm -ivh MySQL-shared-compat-5.6.21-1.el6.i686.rpm
# rpm -qa | grep -i mysql
mysql-libs-5.1.71-1.el6.i686
MySQL-shared-compat-5.6.21-1.el6.i686
# yum remove mysql-libs

测试MySQL-server安装，提示需要安装perl：

# rpm -ivh --test MySQL-server-5.6.21-1.el6.i686.rpm
# yum install perl

–test 安装测试，并不实际安装,可以检查依赖关系

+

三：安装客户端与服务端

cd /usr/local/mysql

安装客户端

rpm -ivh  MySQL-client-5.6.30-1.linux_glibc2.5.x86_64.rpm

安装server

yum install MySQL-server-5.6.30-1.linux_glibc2.5.x86_64.rpm

注意：yum install 和rpm -ivh差不多，猜想差别是yum会自动安装依赖吧。

我遇到的问题，由于我之前编译安装过mysql报了:

Transaction check error:
file /usr/share/mysql/charsets/README from install of MySQL-server-5.6.30-1.linux_glibc2.5.x86_64 conflicts      with file from package mariadb-libs-1:5.5.41-2.el7_0.x86_64

解决方法执行：yum remove mariadb-libs 和yum remove mysql-libs 也不知哪个起到了作用

安装成功会出现以下日志（会产生一个随机的root密码保存在/root/.mysql_secret中）：如果没有这句话顺利安装了，那么密码就是空，初始化让输入旧密码的时候直接回车即可

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.
（一个随机的root密码已经生成被放在'/root/.mysql_secret文件中）
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.

验证中      : MySQL-server-5.6.30-1.linux_glibc2.5.x86_64                                                                                                                                                  1/1
已安装:
MySQL-server.x86_64 0:5.6.30-1.linux_glibc2.5
完毕！

copy配置文件 没有这一步也可以按内置参数

[root@host2 mysql_rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

[root@host2 mysql_rpm]#

四：初始化

查看刚才产生的密码：

cat /root/.mysql_secret

输出：

The random password set for the root user at Thu Apr 28 03:43:28 2016 (local time): TtuLj3wmj345xpmX

启动mysql：

service mysql start

通过mysql_secure_installation执行mysql初始化

[root@localhost xiaoli]# mysql_secure_installation

输出：

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
（下面的意思，输入mysql生成的密码）
Enter current password for root (enter for none):

输入密码：TtuLj3wmj345xpmX

The random password set for the root user at Thu Apr 28 03:43:28 2016 (local time): TtuLj3wmj345xpmX

再次执行：

[root@localhost xiaoli]# mysql_secure_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.
（是否要修改root密码）
Change the root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.
（是否删掉匿名用户？用来测试的果断删除）
Remove anonymous users? [Y/n] y
... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.
（禁止用户远程登录？开发环境安全要求不严格 n，生产环境要求严格 y,我是个严格的人，y）
Disallow root login remotely? [Y/n] y
... Success!

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.
（是否删掉测试数据库，果断y）
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
（重载权限让权限立即生效？y）
Reload privilege tables now? [Y/n] y
... Success!
All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
Cleaning up...
