2.系统中可能存在自带的MySQL,采用命令进行强制删除
rpm –qa|grep mysql
rpm -e mysql-5.1.61 --nodeps强制删除mysql 不考虑依赖关系 (此处根据上一步查询到的结果)
3.安装mysql
rpm -ivh MySQL-server-community-5.1.61-0.rhel5.x86_64.rpm (包名根据实际情况)
4.在MySQL配置文件/etc/my.cnf中根据实际需要添加
lower_case_table_names=1
skip-name-resolve
event_scheduler=1
default-character-set=utf8
wait_timeout=31536000
interactive_timeout=31536000
5.启动服务
cd /etc/init.d
./mysql restart
或者service mysqld restart
6.登陆MySQL
/usr/local/mysql/bin/mysql -u root –p
7.新增用户,根据允许访问的地址和用户,可能需要多次执行。
GRANT ALL PRIVILEGES ON *.* TO 'user'@'192.168.1.1(你的ip)' IDENTIFIED BY 'password' WITH GRANT OPTION
flush privileges
8.
用SQLyog之类的图形化数据库管理工具把数据库备份出来的sql语句执行一遍
9.完成
5. RPM安装步骤a. 检查是否已安装,grep的-i选项表示匹配时忽略大小写
[root@localhost JavaEE]#rpm -qa|grep -i mysql
mysql-libs-5.1.61-4.el6.x86_64
可见已经安装了库文件,应该先卸载,不然会出现覆盖错误。注意卸载时使用了--nodeps选项,忽略了依赖关系:
[root@localhost JavaEE]#rpm -e mysql-libs-5.1.61-4.el6.x86_64 --nodeps
2. 安装MySQL的服务器端软件,注意切换到root用户:
[root@localhost JavaEE]#rpm -ivh MySQL-server-5.5.29-2.el6.x86_64.rpm
安装完成后,安装进程会在Linux中添加一个mysql组,以及属于mysql组的用户mysql。可通过id命令查看:
[root@localhost JavaEE]#id mysql
uid=496(mysql)gid=493(mysql) groups=493(mysql)
MySQL服务器安装之后虽然配置了相关文件,但并没有自动启动mysqld服务,需自行启动:
[root@localhost JavaEE]#service mysql start
Starting MySQL.. SUCCESS!
可通过检查端口是否开启来查看MySQL是否正常启动:
[root@localhost JavaEE]#netstat -anp|grep 3306
tcp0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 34693/mysqld
c. 安装MySQL的客户端软件:
[root@localhost JavaEE]#rpm -ivh MySQL-client-5.5.29-2.el6.x86_64.rpm
如果安装成功应该可以运行mysql命令,注意必须是mysqld服务以及开启:
[root@localhost JavaEE]#mysql

完全没感觉有什么差别只要你不用到 mysql 一些很特殊的用法,应该一样用
XD 我猜你可能会用到类似存储过程、触发器、行级锁
但是只要不用 MySQL的 簇服务器、Plug in API、行级复制
基本上不用太担心这么细微的版本差异
