从mysql网站下载mysql rpm安装包（包括server、client）
1、安装server
rpm -ivh MySQL-server-5.6.19-1.el6.x86_64.rpm
强制安装
rpm -ivh --force MySQL-server-5.5.17-1.linux2.6.x86_64.rpm
报如下错误
[root@iZ257d4pjcoZ ~]# rpm -ivh MySQL-server-5.6.19-1.el6.x86_64.rpm --nodepsPreparing... ################################# [100%]
file /usr/share/mysql/charsets/README from install of MySQL-server-5.6.19-1.el6.x86_64 conflicts with file from package mariadb-libs-1:5.5.40-1.el7_0.x86_64
原因是与之前lib库冲突，解决方式删除老版本lib库（注意根据你的提示更改相应版本）
yum -y remove mariadb-libs-1:5.5.40-1.el7_0.x86_64* yum -y remove mysql-libs-*
再次执行 rpm -ivh MySQL-server-5.6.19-1.el6.x86_64.rpm 即可安装成功
报如下错误
[root@test0001 tools]# rpm -ivh MySQL-server-5.6.19-1.el6.x86_64.rpm error: Failed dependencies: /usr/bin/perl is needed by MySQL-server-5.6.19-1.el6.x86_64 libaio.so.1()(64bit) is needed by MySQL-server-5.6.19-1.el6.x86_64 libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.19-1.el6.x86_64 libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.19-1.el6.x86_64
需要安装 libaio
报如下错误，错少perl安装perl
error: Failed dependencies: /usr/bin/perl is needed by MySQL-server-5.6.19-1.el6.x86_64
安装perl
yum install perl
2、启动mysql
启动
service mysql start
停止
service mysql stop
重启
service mysql restart
查看当前mysql状态
service mysql status
3、安装client
rpm -ivh MySQL-client-5.6.19-1.el6.x86_64.rpm
4、客户端登陆
mysql -uroot -p
5、mysql初始化
[root@xcldtc5m mysql]# /usr/bin/mysql_install_db
[root@xcldtc5m mysql]# service mysql start
[root@xcldtc5m mysql]# cat /root/.mysql_secret
# The random password set for the root user at Sat Feb 7 10:54:24 2015 (local time): VoKvw3vpo_3LiA3c
[root@xcldtc5m mysql]# mysql -uroot -pVoKvw3vpo_3LiA3c
mysql> SET PASSWORD = PASSWORD('2345678');
mysql> exit
[root@xcldtc5m mysql]# mysql -uroot -p2345678
6、远程登录配置
mysql> use mysql
mysql> select host ,user ,password from user;
+-----------+------+-------------------------------------------+
| host | user | password |
+-----------+------+-------------------------------------------+
| localhost | root | *BC1C4715C23459AB982AD2D6617B4F8790161763 |
| xcldtc5m | root | *44CF61DA6CDeeee2085F4598F728CF221DA8F167 |
| 127.0.0.1 | root | *44CF61DA6CD83e32085F4598F728CF221DA8F167 |
| ::1 | root | *44CF61DA6CD86832345F4598F728CF221DA8F167 |
+-----------+------+-------------------------------------------+
mysql> update user set password=password('234567') where user='root';
mysql> update user set host='%' where host='localhost';
mysql> FLUSH PRIVILEGES;
重新启动mysql或是刷新
7、设置开机自启动
[root@xcldtc5m mysql]# chkconfig mysql on [root@xcldtc5m mysql]# chkconfig --list | grep mysql mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
8、查看mysql配置文件位
[root@xcldtc5m mysql]# mysqld --verbose --help | grep -A 1 'Default options'
9、MYSQL默认安装位置
/var/lib/mysql/ #数据库目录 /usr/share/mysql #配置文件目录 /usr/bin #相关命令目录 /etc/init.d/mysql #启动脚本
10、更改mysql默认引擎为Innodb
在配置文件my.ini中的 [mysqld] 下面加入default-storage-engine=INNODB
之后重启即可
