SUSE11
检测系统是否安装MySQL
#rpm -qa | grep -i mysql
若已安装过,会出现:
MySQL-server-5.0.22-0.i386
MySQL-client-5.0.22-0.i386
那么输入以下命令删除它:
#rpm -ev MySQL-server-5.0.22-0.i386
# rpm -ev MySQL-client-5.0.22-0.i386
注意:若删除的时候,出现删除不成功,出现依赖的包,前提必须删除依赖项。rpm -ev dovecot-1.0.7-7.el5.x86_64
在suse11.2-64上先安装一个本地库: 用国内镜像,注意mysql 5.6.22 由于版本更新,所以可以直接访问http://mirrors.sohu.com/mysql/MySQL-5.6/ 查看新的版本,否则wget 下载不到需要的rpm文件.
wget -c http://mirrors.sohu.com/mysql/MySQL-5.6/MySQL-server-5.6.22-1.sles11.x86_64.rpm (for suse11-64版本)
wget -c http://mirrors.sohu.com/mysql/MySQL-5.6/MySQL-client-5.6.22-1.sles11.x86_64.rpm
wget -c http://mirrors.sohu.com/mysql/MySQL-5.6/MySQL-devel-5.6.22-1.sles11.x86_64.rpm
下载完成后开始安装:
rpm -ivh MySQL-server-5.6.22-1.sles11.x86_64.rpm MySQL-client-5.6.22-1.sles11.x86_64.rpm MySQL-devel-5.6.22-1.sles11.x86_64.rpm

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in ‘/root/.mysql_secret‘.
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.
Please report any problems at http://bugs.mysql.com/
The latest information about MySQL is available on the web at
Support MySQL by buying support/licenses at http://shop.mysql.com
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
linux:~ # more .mysql_secret
# The random password set for the root user at Mon Dec 22 16:36:58 2014 (local time): lXNgZ2zmMi1MsIht
linux:/usr # mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 10
Server version: 5.6.22
mysql>
重新设置密码为 123456
mysql> SET PASSWORD = PASSWORD(‘123456‘); #设置密码为123456
mysql> exit
编辑 my.cnf 修改字符集:
[client]
#password = 123456
port = 3306
default-character-set=utf8
[mysqld]
port = 3306
character_set_server=utf8
character_set_client=utf8
collation-server=utf8_general_ci
#(注意linux下mysql安装完后是默认:表名区分大小写,列名不区分大小写; 0:区分大小写,1:不区分大小写)
lower_case_table_names=1
#(设置最大连接数,默认为 151,MySQL服务器允许的最大连接数16384; )
max_connections=1000
[mysql]
default-character-set = utf8
重新启动 service mysql restart ,注意看是否错误.
