Operation notes: Install mysql in Linux

The IT industry is now very popular. With the development of society, technology is becoming more and more advanced, and the knowledge is gradually enriched. So many people begin to learn about Linux. However, we also encountered many problems during our study. Today we will focus on installing Linux mysql. I hope you will learn how to install mysql in Linux through this article.

1. Download the MySQL Installation File
The following two files are required to install MySQL:
MySQL server-5.1.7-0.i386.rpm

Is: http://dev.mysql. com/downloads/mysql/5.1.html. Open this page and find "Linux x86 generic RPM (statically linked against glibc 2.2.5) downloads" in the drop-down list, find the "Server" and "Client programs" items and download the above two rpm files.

2. Install MySQL
The rpm file is a software installation package developed by Red Hat. rpm frees Linux from complicated procedures when installing software packages. The frequently used parameter of this command during installation is-ivh, where I indicates that the specified rmp package will be installed, and V indicates the detailed information during installation, h indicates that the "#" symbol appears during the installation to display the current installation process. This symbol will not stop until the installation is complete.

1) install the server
Run the following command in the directory with two rmp files:

 
 

  
  
[Root @ test1 local] # rpm-ivh MySQL-server-5.1.7-0.i386.rpm for MySQL-client-5.1.7-0.i386.rpm
  
  
The following information is displayed.
  
  
Warning: MySQL-server-5.1.7-0.i386.rpm.
  
  
Signature: NOKEY, key ID 5072e1f5
  
  
Preparing... ######################################## ### [100%]

/Usr/bin/mysqladmin-u root password 'new-password'
  
  
/Usr/bin/mysqladmin-u root-h test1 password 'new-password'
  
  
Starting mysqld daemon with databases from/var/lib/mysql
 
 

If the preceding information is displayed, the Server installation is complete. Run netstat to check whether the Mysql port is opened. If yes, the service is started and the installation is successful. The default Mysql port is 3306.

 
 

  
  
[root@test1 local]# netstat -nat   
  
  
Active Internet connections (servers and established)   
  
  
Proto Recv-Q Send-Q Local Address　Foreign AddressState　  
  
  
tcp00 0.0.0.0:33060.0.0.0:*　LISTEN　 
 
 

The above shows that the MySQL service has been started.

2) install the client
Run the following command:

 
 

  
  
[root@test1 local]# rpm -ivh MySQL -client-5.1.7-0.i386.rpm   
  
  
warning: MySQL -client-5.1.7-0.i386.rpm : V3 DSA signature: NOKEY, key ID 5072e1f5   
  
  
Preparing...########################################### [100%]   
  
  
1:MySQL -client　 ########################################### [100%]  
 
 

The installation is complete.
Use the following command to connect to mysql and test whether the connection is successful.

In this way, you can complete the installation of Linux mysql.
