一、卸载原来的mysql:

卸载一:
输入:
#rpm -qa | grep -i mysql
显示:
mysql-libs-5.1.52-1.el6_0.1.i686
卸载方法:
yum -y remove mysql-libs-5.1.52-1.el6_0.1.i686
 
卸载二:
输入:
#rpm -qa | grep -i mysql
显示:
MySQL-client-5.1.62-1.glibc23.i386
MySQL-server-5.1.62-1.glibc23.i386
卸载方法:
#rpm -ev MySQL-client-5.1.62-1.glibc23.i386 MySQL-server-5.1.62-1.glibc23.i386
 
二、安装MySQL服务器端:
安装文件:MySQL-server-5.1.62-1.glibc23.i386.rpm
# rpm -ivh /software/mysql/MySQL-server-5.1.62-1.glibc23.i386.rpm
这是在/usr/share/mysql 目录下生成一些 文件,其中有一个文件名为:my-medium.cnf 将其拷贝到/etc/my.cnf中
# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
现在就安装完了,可以看看他运行的进程:
# ps -ef | grep mysql
 
三、安装MySQL客户端:
# rpm -ivh /software/mysql/MySQL-client-5.1.62-1.glibc23.i386.rpm
现在就安装客户端成功了,可以看看关于MySQL一些文件:
# ls /usr/bin/mysql*
 
四、登录mysql:
刚开始装上mysql时是没有密码的,输入:
# mysql
就可登录到mysql数据库上了。
 
五、设置MySQL密码:
# mysqladmin -u root password 123456
这样就将mysql中用户名为root密码设为123456
 
六、登录设置有密码的mysql:
命令和dos下登录mysql是一样的:
# mysql -uroot -p123456
或者
# mysql -uroot -p[回车]
再输入密码

MySQL BLOB: how to optimize BLOBs requestsMySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
