CentOS 6.6下安装MySQL 5.6.24
1、先查看本机上已经安装的MySQL
rpm –qa | grep -i mysql
如果存在信息说明已经安装MySQL
需要完全卸载以前的MySQL
yum remove mysql mysql-server mysql-libs compat-mysql51
rm -rf /var/lib/mysql
rm /etc/my.cnf
查看是否还有mysql软件:
rpm -qa|grep mysql
如果存在的话,继续删除即可
2、rpm方式安装的mysql
查看系统中是否以rpm包安装的mysql:
[root@develop ~]# rpm -qa | grep -i mysql
MySQL-server-5.6.24-1.rhel5.x86_64
[root@develop ~]#
b)卸载mysql
[root@localhost local]# rpm -e MySQL-server-5.6.24-1.rhel5.x86_64
c)删除mysql服务
[root@localhost local]# chkconfig --list | grep -i mysql
[root@develop ~]# chkconfig --list | grep -i mysql
mysql 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
[root@localhost local]# chkconfig --del mysql
d)删除分散mysql文件夹
[root@localhost local]# whereis mysql 或者 find / -name mysql
mysql: /usr/lib/mysql /usr/share/mysql
清空相关mysql的所有目录以及文件
rm -rf /usr/lib/mysql
rm -rf /usr/share/mysql
rm -rf /usr/my.cnf
通过以上几步,mysql应该已经完全卸载干净了
使用wget 直接在CentOS上下载MySQL(server、client)
若提示wget:command not found,则需先安装wget。
yum install wget –y
下载
wget
wget
安装时若提Failed depaendencies:/usr/bin/perl is needed by MySQL-.......,则需安装perl
yum install perl -y
安装:
安装服务
rpm -ivh MySQL-server-5.6.24-1.rhel5.x86_64.rpm
安装客户端
rpm -ivh MySQL-client-5.6.24-1.rhel5.x86_64.rpm
conflicts with file from package mysql-libs-5.1.....
包冲突,需将老版本的包卸载(删除)。
rpm -e mysql-libs --nodeps
继续安装。。。
安装完毕,启动数据库
service mysql start
输入:mysqld
提示:
image
这个是MySQL的权限问题。
永远不要使用root帐号启动MySQL Server。这样做很微笑,因为拥有FILE'权限的用户会使得MySQL Server使用root帐户创建文件(比如,~root/.bashrc),
为了防止类似的事情发生,mysqld默认拒绝用户使用root帐户启动,但root用户可以通过在命令后面加上"--user=root"选项来强行启动mysqld。
查看初始密码
cat /root/.mysql_secret
设置密码
mysql -uroot -p
粘贴查看到的初始密码
set password for 'root'@'localhost'=password('newpass');
设置mysql为开机自动启动
首先查看mysql是否是开机自动启动
-------------------------------------------------------
[root@localhost test]# chkconfig --list | grep mysql
mysqld 0:off 1:off 2:off 3:off 4:off 5:off 6:off
---------------------------------------------------------
我们发现mysqld服务并没有开机自动启动,我们当然可以通过 chkconfig mysqld on 命令来将其设置成开机启动,这样就不用每次都去手动启动了
设置初始化密码
mysqladmin -u root password '123456'
test->show databases;
关闭mysql数据库
service mysql stop
3、卸载mysql数据库
rpm -e MySQL-server
rpm -e MySQL-client
CentOS下mysql默认安装位置
如果采用RPM包安装,,安装路径应在/usr/share/mysql目录下
mysqldump文件位置:/usr/bin/mysqldump
mysqli配置文件:
/etc/my.cnf或/usr/share/mysql/my.cnf
mysql数据目录在/var/lib/mysql目录下
如果采用源代码安装,一般默认安装在/usr/local/mysql目录下

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.
