Centos6.9安装Myql数据库RPM包

1、进入/usr/src目录

[root@ljctest nginx-1.12.1]# cd /usr/src/

[root@ljctest src]# ls

debug kernels nginx-1.12.1 nginx-1.12.1.tar.gz

2、下载Myql5.7.19的rpm包

[root@ljctest****src]#wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.19-1.el6.x86_64.rpm-bundle.tar

--2017-10-12 11:16:50-- https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.19-1.el6.x86_64.rpm-bundle.tar

3、查看文件！

[root@ljctest src]# file mysql-5.7.19-1.el6.x86_64.rpm-bundle.tar

mysql-5.7.19-1.el6.x86_64.rpm-bundle.tar: POSIX tar archive (GNU)

4、创建mysql-5.7的目录

[root@ljctest src]# mkdir mysql-5.7

5、解压RPM包到mysql-5.7文件夹中

[root@ljctest src]# tar -xf mysql-5.7.19-1.el6.x86_64.rpm-bundle.tar -C mysql-5.7/

6、****检查操作系统上是否安装了MySQL

[root@mydb1 backup]# rpm -qa |grep mysql 
qt-mysql-4.6.2-26.el6_4.x86_64 
mysql-5.1.71-1.el6.x86_64 
mysql-server-5.1.71-1.el6.x86_64 
mysql-devel-5.1.71-1.el6.x86_64 
mysql-libs-5.1.71-1.el6.x86_64

删除MyQL(RedHat6.3服务器自带的mysql-libs是mysql-libs-5.1.61-4.el6.x86_64，可能会和高版本的mysql-libs有冲突)

yum remove mysql-libs

7、单独安装报错（一般都是依赖安装的有问题）！

[root@ljctest mysql-5.7]# rpm -ivh mysql-community-server-5.7.19-1.el6.x86_64.rpm

warning: mysql-community-server-5.7.19-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

8、有网络的情况，用如下的安装方式安装，安装成功。

[root@ljctest mysql-5.7]# yum install ./*.rpm

9、启动mysql

[root@ljctest mysql-5.7]# service mysqld start

Initializing MySQL database: [ OK ]

Starting mysqld: [ OK ]

[root@ljctest mysql-5.7]#

[root@ljctest mysql-5.7]# grep 'temporary password' /var/log/mysqld.log

2017-10-12T07:20:33.419494Z 1 [Note] A temporary password is generated for root@localhost: ?OJo0_Wrpv70

[root@ljctest mysql-5.7]#

10、进入mysql ，修改mysql的密码。

[root@ljctest mysql-5.7]# mysql -uroot -p

Enter password:

以上，MySQL 5.7.10安装完成。

之后还可以放开防火墙、设定自启动、增强MySQL安全设置等。

iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT

/etc/init.d/iptables save

chkconfig mysqld on
