新的项目启动了,要做托管型的呼叫中心,分析了竞争对手的业务流程,大概估计是基于asterisk开发出来的,前阵子看到一个开源的项目asterCRM,有部分

呼叫中心和CRM的功能,所以新搭建一个Linux环境分析下,昨天已经安装了RedHat 4,接下来我需要安装MySQL:

通过rpm包安装、配置及卸载mysql的详细过程.

以MySQL-server-4.0.14-0.i386.rpm为例,,放在/usr/src目录下

cd /usr/src

rpm -ivh MySQL-server-4.0.14-0.i386.rpm

安装完成后在/usr/share/mysql目录中会有一个mysql的启动脚本mysql.server及示例配置文件等(如my-huge.cnf、my-large.cnf、my-medium.cnf)

拷贝一个示例配置文件作为mysql的配置文件:

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

rpm包安装完后自动将mysql安装成系统服务,所以可以使用下面命令启动、停止mysql

启动mysql

/etc/init.d/mysql start 或 service mysql start

停止mysql

/etc/init.d/mysql stop 或 service mysql stop

到此,mysql服务就安装配置完成。

安装mysql客户端

rpm -ivh MySQL-client-4.0.14-0.i386.rpm

mysql安装好后目录结构如下:

工具程序在/usr/bin目录中---ls /usr/bin/mysql*

服务器程序/usr/sbin/mysqld

数据目录/var/lib/mysql

默认情况下mysql将错误日志文件、二进制日志文件及进程文件写在/var/lib/mysql目录中,如localhost.err、localhost.pid、localhost-bin.001等

要改变这些情况可以修改/etc/my.cnf文件

如将日志文件写在/var/log目录中,可以在my.cnf文件中加入下面两行:

[mysqld_safe]

err-log = /var/log/mysqld.log

有个实用程序/usr/bin/mysql_install_db,该程序可以用来初始化mysql数据库,即创建/var/log/mysql目录,及创建mysql数据库(mysql授权表等信息)及test数据库(空库),如果不小心删除了/var/log/mysql目录可以通过该程序来初始化.

卸载mysql

rpm -qa|grep -i mysql

rpm -ev MySQL-server-4.0.14-0 MySQL-client-4.0.14-0

卸载后/var/lib/mysql中的数据及/etc/my.cnf不会删除,如果确定没用后就手工删除

rm -f /etc/my.cnf

rm -rf /var/lib/mysql

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.

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

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.
