HOW TO INSTALL LAMP ON CENTOS 7 (httpd, php, mariadb, myphpadmin)

INSTALL APACHE WEB SERVER

Being the most popular web server, Apache is commonly included in most of recent Linux Distro so installation will be very easy.

Before you proceed to the next steps, it is better to explain that all commands in this tutorial are written without the “sudo” prefix. In this tutorial I use root but you may alsologin as separate user with root privilege. However if you disabled root login and you logged in using another username with root privilege, you can add the “sudo” prefix all by your self. Alternatively you can simply type su, hit Enter and type in your password twice to switch as root.

Step 1 – Login to your server via Putty or Terminal.

 

 

Step 2 – Now issue command below to install Apache 2.4 on your CentOS 7 server:

 

 

1	yum install httpd -y

 

 

As you can see the command is still the same.

 

 

And when the process finished, you’ll see something like this:

 

 

Step 3 – Now you have Apache 2.4 installed which you can then start the service by typing command below:

 

 

1	systemctl start httpd.service

 

 

or,..

 

 

1	service httpd start

 

 

 

 

Available commands:

 

 

1 2 3 4 5

systemctl status|start|stop|restart|reload httpd.service   # OR, old command :   service httpd status|start|stop|restart|reload

 

 

Step 4 – You can verify that Apache is really running by opening your favorite web browser and access your vps via its IP address:

http://xxx.xxx.xxx.xxx

and you’ll see default Apache welcome page.

In current example I’ve installed Apache v2.4.6.

or, you can directly issue this command:

systemctl status httpd.service

you’ll see something like this:

Enable Apache to automatically run every time your server reboot:

1	systemctl enable httpd.service

INSTALL PHP5 -삭제

INSTALL PHP7 

 

먼저, 

# yum info php | egrep 'Name|Version'

하면 인식되는 php이름이랑 버전이 나올것인데, 대충 버전 결과값이 5.4로 되어있을것임.

 

이펠 설치 안되어 있음 이펠 설치하자. 아마 yum update했으니까 안깔아도 깔려있을거임

# yum -y install epel-release

그리고 레미? 리미? 저장소 깔자. 그리고 php7버전을 활성화 시켜주자.

# yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm # yum-config-manager --enable remi-php72

만약 여기서 yum-config-manager 명령어를 찾을수 없다고 나오면,

 

# yum install yum-utils

한번 설치 해주면 먹힌다.

 

php 7.2 설치

# yum install -y php # php -v   PHP 7.2.18 (cli) (built: Apr 30 2019 15:26:52) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

INSTALL MARIADB MYSQL SERVER

Step 6 – Installing MariaDB mysql server on CentOS 7 is pretty easy and once again we’ll make us of yum package manager:

1	yum install mariadb-server mariadb -y

and once done you’ll see something like this:

Step 7 – Now you can start MariaDB server for the very first time using this simple systemctl command :

1	systemctl start mariadb.service

You may also see the status of MariaDB by typing:

systemctl status mariadb

MARIADB INITIAL CONFIGURATION

Step 8 – So its service is now running but there is one thing you should do immediately: configuring MariaDB setup for the very first time like setting up your mysql root password. Issue this command:

1	mysql_secure_installation

Then you’ll see a series of question, just answer it accordingly. The main important part is to define your root password while everything else is just up to you or you can simply hit the “ENTER” key through each prompt to accept the default values.

If you need to automatically run MariaDB everytime your server boot, simply issue this command:

1	systemctl enable mariadb.service

You may also need to test your newly installed MariaDB by logging in as root:

1	mysql -u root -p

As you can see from the screenshot above, it is Maria DB v5.5.37.

Step 9 – Also test if Apache and PHP is running well and able to process any *.php files. Create a php info page using this command followed by restarting apache

1	echo "<?php phpinfo(); ?>" > /var/www/html/info.php

Restart apache:

1	systemctl restart httpd.service

Now open up your browser and access that newly created php page:

http://xxx.xxx.xxx.xxx/info.php

You’ll see a page similar to this one:

 

 

+ firewall configure -> info.php 페이지가 보임

 

3. On the next step start Apache service using systemd init script and open RHEL/CentOS 7.0 Firewall rules using firewall-cmd, which is the default command to manage iptables throughfirewalld daemon.

# firewall-cmd --add-service=http

NOTE: Make notice that using this rule will lose its effect after a system reboot or firewalld service restart, because it opens on-fly rules, which are not applied permanently. To apply consistency iptables rules on firewall use –permanent option and restart firewalld service to take effect.

# firewall-cmd --permanent --add-service=http # systemctl restart firewalld

Enable Firewall in CentOS 7

Other important Firewalld options are presented below:

# firewall-cmd --state # firewall-cmd --list-all # firewall-cmd --list-interfaces # firewall-cmd --get-service # firewall-cmd --query-service service_name # firewall-cmd --add-port=8080/tcp

INSTALLING PHPMYADMIN

Step 10 – Now your server has Apace, PHP and MariaDB installed. It means it should be OK now to install PhpMyAdmin, a popular web-based database management system so you can easily manage your database without having to login via SSH and issuing several command lines. Unluckily, this piece of awesome software is not available in CentOS 7.0 default repositories. In this case you have to add / enable third-party repo like EPEL orRPMForge.

Method #1: RPMForge

First, download the rpm file.

1	wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm

then enable the repository and delete the .rpm file as it is not needed again.

1 2	rpm -ivh rpmforge-release-* rm rpmforge-release-*

Method #2: EPEL

Download the .rpm file:

1	wget http://download.fedoraproject.org/pub/epel/beta/7/x86_64/epel-release-7-0.2.noarch.rpm

The url above is still its beta version. However if the repository is out of beta status, the link most likely will be different. In case that happens, you can find out its latest download url at Fedora Project website.

enable the repository and delete the .rpm file:

1 2	rpm -ivh epel-release* rm epel-release*

 

Step 10 - epel저장소 추가 및 인스톨

yum install epel-release

yum update

2. 그리고 나서 phpmyadmin을 설치해주자.

yum install phpmyadmin

 

 

Step 11 – Next, install it using yum again:

1	yum install phpmyadmin -y

screenshot:

Step 12 – That’s it. Now you also have phpMyAdmin (PMA) installed but you should be better if you change its default configuration before using it. First, you’ll need to backup default PMA’s config file:

1	cp /etc/httpd/conf.d/phpMyAdmin.conf /etc/httpd/conf.d/phpMyAdmin.conf.old

then edit file phpMyAdmin.conf file using your favorite editor. In this example I use Nano editor:

1	nano /etc/httpd/conf.d/phpMyAdmin.conf

Step 13 – You’ll now see the content of phpMyAdmin.conf, next you have to allow connections from remote hosts by editing few lines inside section <Directory “/usr/share/phpMyAdmin”>.

Before changes:

After:

Also you’ll need to edit few lines next:

Before:

After:

Shortly it should look like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<Directory /usr/share/phpMyAdmin/>    <IfModule mod_authz_core.c>      # Apache 2.4      <RequireAny>        Require all granted      </RequireAny>    </IfModule>    <IfModule !mod_authz_core.c>      # Apache 2.2      #Order Deny,Allow      #Deny from All      AllowOverride None      Options None      Allow from All      Require all granted    </IfModule> </Directory>

Once done, save and exit editor (In Nano it is Control+O then Control+X).

Step 14 – Restart Apache again::

1	systemctl restart httpd.service

Now you can test opening PMA on your browser via your server’s IP address:

http://xxx.xxx.xxx.xxx/phpmyadmin

and default login page of phpMyAdmin should be displayed:

 

That’s all. Now you can host your websites or blogs in that server, even WordPress.
