How to build a LAMP environment in centos7.2

1. Installation of apache, php and mysql

Installation order: apache/mysql and finally install php. The order of the first two does not matter.

1. Installationapache

Requires server networking

Installation:yum install -y httpd

Run: /bin/systemctl start httpd.service

After executing the run command, you will not see the effect. At this time, enter the check apache service status command to check whether the service has been started:

View status: service httpd status

## Apache Start service: systemctl start httpd

ApacheStop service: systemctl stop httpd

## To test whether the apache service is started normally, enter the public address of the cloud server in our local browser Networkip, I am taking 118.89.32.6 as an example

As shown above, it means

apache is opened normally;

2. Install mysql

　　rpm -ivh mysql-community-release-el7-5.noarch.rpm
　　yum install mysql-community-server　　　After successful installation, restart
mysql service

　　

　 service mysqld restart

Initial installation

mysql is the root account and does not have a password How to set a password
：## Enter

mysql -uroot

to enter the mysql database　　　　mysql>
set password for 'root'@'localhost' = password('mypasswd'); 　　 mysql>
exit## 　　 If an error is reported: can't find any matching row in the user table Execute the following statement

##　mysql> grant all privileges on testDB.* to 'test'@' 1.1.1.1'identified by 'yourpassword';

This time the prompt is executed successfully, but don’t forget to execute it again:

mysql> FLUSH PRIVILEGES; Make changes in time Write grant table

Remote authorization connectionmysql

　

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@' %' IDENTIFIED BY 'The database password you want to set
' WITH GRANT OPTION;　mysql>FLUSH PRIVILEGES;

Removal software：yum remove foo-x.x.x.rpmoryum erase foo-x.x.x.rpm

Upgrade software: yum upgrade foo or yum update fo

Query information：yum info foo

Search software (to include the foo field For example)：yum search foo

Display package dependencies：yum deplist foo

3. One-click installation: (convenient and easy ^_^)

##　

One-click installation package is required. I am using the installation package provided by Alibaba Cloud:

Open

xshell,Enter the xftp interface: will Drag the local installation package into the remote server root directory:

Switch to the

xshell window and enter the root directory: cd /root

in sequence Type the following command to install

:

2. ./install.sh

The remaining configuration steps are the same as above. The specific directories are as follows:

After that, you can use xftp Upload your project to the root directory of the website.
