二、概述
1.环境准备
(1).安装yum源
[root@node6 src]# wget [root@node6 src]# rpm -ivh epel-release-6-8.noarch.rpm(2).同步时间(系统与硬件)
[root@node6 src]# yum install -y ntp [root@node6 src]# ntpdate 202.120.2.101 [root@node6 src]# hwclock -w2.安装mysql 5.1
[root@node6 mysql-5.1.73]# tar xf mysql-5.1.73.tar.gz [root@node6 mysql-5.1.73]# cd mysql-5.1.73 [root@node6 mysql-5.1.73]# ./configure --prefix=/usr/local/mysql --localstatedir=/data/mysql --enable-assembler --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --with-pthread --enable-static --with-big-tables --without-ndb-debug --with-charset=utf8 --with-extra-charsets=all --without-debug --enable-thread-safe-client --enable-local-infile --with-plugins=max出错1:checking for termcap functions library... configure: error: No curses/termcap library found。
原因:缺少ncurses安装包。
解决方法,
[root@node6 mysql-5.1.73]# yum -y install ncurses ncurses-devel下面继续,
[root@node6 mysql-5.1.73]# ./configure --prefix=/usr/local/mysql --localstatedir=/data/mysql --enable-assembler --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --with-pthread --enable-static --with-big-tables --without-ndb-debug --with-charset=utf8 --with-extra-charsets=all --without-debug --enable-thread-safe-client --enable-local-infile --with-plugins=max上面配置内容省略……
This version of MySQL Cluster is no longer maintained. Please use the separate sources provided for MySQL Cluster instead. See for more details. Thank you for choosing MySQL! Remember to check the platform specific part of the reference manual for hints about installing MySQL on your platform. Also have a look at the files in the Docs directory.到这里我们编译配置就完成了,下面我们编译并安装。
[root@node6 mysql-5.1.73]# make && make install注,编译与安装时间比较长请大家耐心等待,当然会看各位博友机器的配置,相对来说配置越好,相对的编译与安装时间相对就少。
3.创建数据目录并授权
[root@node6 mysql-5.1.73]# mkdir -pv /data/mysql mkdir: 已创建目录 "/data/mysql" [root@node6 mysql-5.1.73]# useradd mysql [root@node6 mysql-5.1.73]# chown mysql.mysql /data/mysql/ [root@node6 mysql-5.1.73]# ll /data/ 总用量 20 drwx------. 2 root root 16384 8月 17 18:42 lost+found drwxr-xr-x. 2 mysql mysql 4096 1月 4 16:10 mysql4.为mysql提供配置文件
[root@node6 mysql-5.1.73]# cp support-files/my-huge.cnf /etc/my.cnf cp:是否覆盖"/etc/my.cnf"? y5.简单修改一下配置文件
[root@node6 mysql-5.1.73]# vim /etc/my.cnf [client] default-character-set = utf8 [mysqld] default-character-set = utf8 datadir = /data/mysql6.提供启动脚本
[root@node6 mysql-5.1.73]# cp support-files/mysql.server /etc/init.d/mysqld [root@node6 mysql-5.1.73]# chmod +x /etc/init.d/mysqld [root@node6 ~]# chkconfig mysqld --add [root@node6 ~]# chkconfig mysqld on7.初始化mysql
[root@node6 mysql-5.1.73]# /usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql/ --datadir=/data/mysql/ --user=mysql Installing MySQL system tables... 140104 16:18:43 [Warning] '--default-character-set' is deprecated and will be removed in a future release. Please use '--character-set-server' instead. 140104 16:18:43 [Warning] '--skip-locking' is deprecated and will be removed in a future release. Please use '--skip-external-locking' instead. OK Filling help tables... 140104 16:18:43 [Warning] '--default-character-set' is deprecated and will be removed in a future release. Please use '--character-set-server' instead. 140104 16:18:43 [Warning] '--skip-locking' is deprecated and will be removed in a future release. Please use '--skip-external-locking' instead. OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands: /usr/local/mysql//bin/mysqladmin -u root password 'new-password' /usr/local/mysql//bin/mysqladmin -u root -h node6.test.com password 'new-password' Alternatively you can run: /usr/local/mysql//bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd /usr/local/mysql/ ; /usr/local/mysql//bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd /usr/local/mysql//mysql-test ; perl mysql-test-run.pl Please report any problems with the /usr/local/mysql//scripts/mysqlbug script!注,从上面的内容中我们看到了几个警告,我们查看一下。
140104 16:18:43 [Warning] '--default-character-set' is deprecated and will be removed in a future release. Please use '--character-set-server' instead. 140104 16:18:43 [Warning] '--skip-locking' is deprecated and will be removed in a future release. Please use '--skip-external-locking' instead. OK Filling help tables... 140104 16:18:43 [Warning] '--default-character-set' is deprecated and will be removed in a future release. Please use '--character-set-server' instead. 140104 16:18:43 [Warning] '--skip-locking' is deprecated and will be removed in a future release. Please use '--skip-external-locking' instead.从上面的警告可以看到,--default-character-set、--skip-locking选项已经过时,建议使用--character-set-server、--skip-external-locking。
8.查看一下初始化目录
[root@node6 data]# ls /data/mysql/ mysql mysql-bin.000001 mysql-bin.000002 mysql-bin.index test9.启动一下mysql
[root@node6 ~]# service mysqld start Starting MySQL.. SUCCESS!
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.

MySQL is suitable for beginners because: 1) easy to install and configure, 2) rich learning resources, 3) intuitive SQL syntax, 4) powerful tool support. Nevertheless, beginners need to overcome challenges such as database design, query optimization, security management, and data backup.

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
