最近在学习mysql，发现其实在linux下安装的时候还是挺麻烦的，于是做个记录和大家分享，不足之处，欢迎留言指正

一,下载并上传至linux

首先下载tar文件放到/usr/local/链接：http://pan.baidu.com/s/1kVtnpdX 密码：3r40

解压到指定目录mkdir mysql

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

二,安装到mysql-client,mysql-server

切换到mysql目录cd /usr/local/mysql

安装mysql-clientrpm -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

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

file /usr/share/mysql/czech/errmsg.sys 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

file /usr/share/mysql/danish/errmsg.sys from install of MySQL-server-5...

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

安装日志的一段(生成一个随机密码到/root/.mysql_secret)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.

New default config file was created as /usr/my.cnf and

will be used by default by the server when you start it.

You may edit this file to change server settings

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！

启动mysql

service mysql start

三,初始化

查看刚才生成的密码

[root@localhost xiaoli]# cat /root/.mysql_secret

通过 mysql_secure_installation执行一些初始化

[root@localhost xiaoli]# mysql_secure_installation

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

[root@localhost xiaoli]# mysql_secure_installation

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.

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...

安装完毕 ！！！
