Installing MySQL in a Linux environment

There are two methods, one is source installation, and the other is RPM installation. Mainly the latter:

2. First Check if it is installed, and the-I option of grep indicates that the case is ignored when matching . Rpm-qa|grep-i MySQL. The uninstallation that will be detected. rpm-e mysql-libs-5.1.61-4.el6.x86_64--nodeps (represents ignoring dependencies)

4. Install the server-side software for MySQL, and note the switch to the root user.  RPM-IVH mysql-server-5.5.29-1.rhel5.i386.rpm. installation When finished, the installation process adds a MySQL group to Linux and MySQL for users who belong to the MySQL group. Can be viewed through the ID command.

6. My After the SQL Server installation, although the relevant files are configured, but do not automatically start the MYSQLD service, you need to start: service MySQL start.netstat-anp|grep 3306 is used to detect whether it is started.

7. < Span style= "Color:rgb (51,51,51); Font-family:arial;font-size:14px;line-height:26px;background-color:rgb ( 255,255,255); " > Install the client software. Some are installed at the end of the installation service.

   < Span style= "Color:rgb (51,51,51); Font-family:arial;font-size:14px;line-height:26px;background-color:rgb ( 255,255,255); " >

Relative to the RPM installation, the source code installation will be much more complex, temporarily regardless.

Summary: Delete the installed MySQL-related programs, then install the server-side and install the client first.
