1.上傳mysql安裝軟件
MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle.tar
2.解壓mysql安裝包
tar -xvf MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle.tar
MySQL-server-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-shared-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-devel-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-client-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-shared-compat-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-embedded-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-test-5.6.26-1.linux_glibc2.5.x86_64.rpm
3.安裝mysql服務端
rpm -ivh MySQL-server-5.6.26-1.linux_glibc2.5.x86_64.rpm
查看端口 netstat -nltp 端口3306
如果mysql服務器沒有啓動，則啓動服務
service mysql start
4.如果安裝mysql發生衝突，如果沒有衝突，直接跳過第5步
rpm -e mariadb-libs-1:5.5.56-2.el7.x86_64 --nodeps
5.安裝mysql服務端
rpm -ivh MySQL-server-5.6.26-1.linux_glibc2.5.x86_64.rpm
查看端口 netstat -nltp 端口3306
如果mysql服務器沒有啓動，則啓動服務
service mysql start
6.修改密碼
默認密碼：cat /root/.mysql_secret fiUnZpQZgYH3YiVl
修改密碼
a.使用客戶端修改
/usr/bin/mysql_secure_installation
安裝mysql客戶端
rpm -ivh MySQL-client-5.6.26-1.linux_glibc2.5.x86_64.rpm
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] n
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y
7.登錄mysql
mysql -uroot -proot
8.查看mysql數據庫
show databases;
9.退出
exit;
10.授權用戶遠程機器登錄
a.) grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option;
b.) flush privileges;
備註： *.* 所有庫.所有表 'root'@'%' root可以從任何地方訪問
-----------------------------
Q & A
1.缺少perl,
/usr/bin/perl is needed by MySQL-server-5...
libaio.so.1() is needed by MySQL-server-5...
yum list | grep perl
yum install -y perl.x86_64
2.lib io
yum list | grep libaio
yum install -y ;libaio.x86_64
3.掛載軟件
mount -t iso9660 -o loop /dev/cdrom /mnt/cdrom
如果cdrom已經掛載過了，修改一下yum源
cd /etc/yum.repos.d/
ll
cat dvd.repo
baseurl=file:///mnt/cdrom
