Way

首先去http://dev.mysql.com/downloads/mysql/5.5.html#downloads站点下载：

分别下载以下三个文件（由于我的机器是32位，下面是32位版本的包，如果你的机器是64位的请下载64位版本）：

MySQL-server-5.5.16-1.rhel5.i386.rpm

MySQL-client-5.5.16-1.rhel4.i386.rpm

MySQL-devel-5.5.16-1.rhel4.i386.rpm

使用wget命令使用断点传输的方式将这三个文件下载

wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-server-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/

wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-client-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/

wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-devel-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/

下载完成后开始安装：

rpm -ivh MySQL-server-5.5.16-1.rhel4.i386.rpm MySQL-client-5.5.16-1.rhel4.i386.rpm MySQL-devel-5.5.16-1.rhel4.i386.rpm

提示安装完成后，输入mysql 看是否安装成功

mysql

如果出现如下错误信息：

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

说明mysql服务还没有启动，输入service mysql start启动mysql服务

service mysql start

然后再输入mysql，若出现以下提示信息，说明成功。

Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.5.16 MySQL Community Server (GPL)

owners.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

首次安装时，默认密码为空，可以使用如下命令修改root密码，

mysqladmin -u root password mypassword

mypassword 为你设定的新密码

然后再次登录

mysql -u root –p

rpm包安装的MySQL是不会安装/etc/my.cnf文件的，解决方法，只需要复制/usr/share/mysql目录下的my-huge.cnf 文件到/etc目录，并改名为my.cnf即可

cp /usr/share/mysql/my-huge.cnf /etc/my.cnf

配置远程访问

处于安全考虑，Mysql默认是不允许远程访问的，可以使用下面开启远程访问

//赋予任何主机访问数据的权限
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION

//使修改生效
mysql>FLUSH PRIVILEGES

如果依然不能远程访问的话，那就很可能防火墙的原因了，可以在防火墙中开启3306端口或者干脆关掉防火墙。

MySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AM

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

MySQL: What length should I use for VARCHARs?May 09, 2025 am 12:06 AM

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
