(一)
#./configure --prefix=/usr/local/mysql-5.1.54
(mysql指定路径安装报错:)
checking for termcap functions library... configure: error: No curses/termcap library found 安装:
ncurses-devel.***.rpm 包解决
#cd /media/CentOS_5.5_Final/CentOS/
#ls ncurses-devel*
找到这个包并用rpm安装。
# rpm -ivh ncurses-devel-5.5-24.20060715.i386.rpm (或者去下载一个ncurses-5.6.tar.gz,
wget http://ftp.gnu.org/pub/gnu/ncurses/ncurses-5.6.tar.gz 解压并安装)
(二)
make时出错
../depcomp: line 571: exec: g++: not found
make[1]: *** [my_new.o] 错误 127
make[1]: Leaving directory `/usr/local/src/mysql/mysql-5.1.32/mysys`
make: *** [all-recursive] 错误 1
解决:
#yum install gcc-c++ 可解决问题。 重新指定安装路径:
#./configure --prefix=/usr/local/mysql-5.0.90 make make install ?
(三)
初始化数据库时出错:
# scripts/mysql_install_db --user=mysql
或
#bin/mysql_install_db --basedir=/usr/local/mysql-5.1.54 --datadir=/usr/local/mysql-5.1.54/data --user=mysql [Warning] '--skip-locking' is deprecated and will be removed in a future release. Please use '--skip- external-locking' instead.
?
(解决方法:将my.cnf 中的'--skip-locking' 换成'--skip-external-locking' 就可以了。) ? (四)修改/etc/my.cnf 的配置文件: [client]
#password = your_password
port = 3306
socket = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server
[mysqld]
port = 3306
socket = /tmp/mysql.sock basedir=/usr/local/mysql-5.1.54
datadir=/usr/local/mysql-5.1.54/data skip-external-locking
key_buffer_size = 16M
max_allowed_packet = 1M
table_open_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K

read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M [mysql]

(五:提示:) 出错时,可及时查看错误日志:
vi /usr/local/mysql-5.1.54/data/localhost.localdomain.err 显示如下:

(1)
#cd /usr/local/ mysql-5.1.54/libexec
#./mysqld --defaults-file=../my.cnf --user=mysql (2)
#cd /usr/local/mysql-5.1.54/bin

#mysql -S /tmp/mysql.sock (4)
#cd /usr/local/mysql-5.1.54/share/mysql

(可以将mysql添加的系统服务中)
#cp ./mysql.server /etc/init.d/mysql
#chkconfig --add mysql
#service mysql start

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.
