Install LAMP PHP5.4 in CentOS yum

Install LAMP PHP5.4 in CentOS yum

Linux: CentOS 6.5

1. there is no difference between yum installation and source code compilation, but the installation process is quite different. yum only requires three commands to complete. The source code requires 13 packages and requires pressure compilation, the steps are troublesome and sometimes errors occur. It takes about two hours to compile and install the source code. The advantage is that you can configure parameters such as the address by yourself. yum will be installed for half an hour and will not cause errors, it is easy to update.

2. my machine is a CentOS release 5.9 64-bit system. Generally, the machine carries the yum command, and the yum package source can be used, that is, you do not need to download it yourself, directly add the software you want to install after yum-y install. It will automatically download and automatically install the software, which is very convenient. For example, yum-y install httpd automatically downloads and installs the apache server. In the lamp environment, you only need to install httpd, mysql, and php.

3. update yum-y update first.

4. install Apache, Mysql, and PHP with yum.

4.1 install Apache
Yum install httpd-devel
After the installation is complete, start apache with/etc/init. d/httpd start
Set to boot: chkconfig httpd on

4.2 install mysql
Yum install mysql-server mysql-devel
Similarly, start mysql with/etc/init. d/mysqld start

4.3 set the mysql password
Mysql>; USE mysql;
Mysql>; UPDATE user SET Password = PASSWORD ('newpassword') WHERE user = 'root ';
Mysql>; flush privileges;

You can also use the mysql_secure_installation command to set the mysql password.

4.4 Allow Remote Login
Mysql-u root-p
Enter Password: <your new password>
Mysql> grant all privileges on *. * TO 'username '@' % 'identified by 'Password' with grant option;
After that, you can use mysql-front to remotely manage mysql.
Set to boot
Chkconfig mysqld on
