linux中源码编译安装mysql常见错误_MySQL
(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_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M [mysql]
no-auto-rehash
# Remove the next comment character if you are not familiar with SQL
#safe-updates
(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:
110107 22:06:31 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql-5.1.54/data
110107 22:06:31 [Warning] '--skip-locking' is deprecated and will be removed in a future release. Please use '--skip-external-locking' instead.
/usr/local/mysql-5.1.54/libexec/mysqld: Table 'mysql.plugin' doesn't exist
110107 22:06:31 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

110107 22:06:31 [ERROR] Do you already have another mysqld server running on socket: var/lib/mysql/mysql.sock ?
110107 22:06:31 [ERROR] Aborting ? 小结1: mysql 的启动方式:
(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
#./mysqld_safe --defaults-file=../my.cnf --user=mysql (3)
#mysql -S /tmp/mysql.sock (4)
#cd /usr/local/mysql-5.1.54/share/mysql
#./mysql.server start
(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

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.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.
