How To Install Apache SVN on CentOS 7

Apache Subversion which is commonly referred to in its abbreviated form as SVN, (named after the command name SVN) is a popular software versioning and revision control system which is distributed as a free software under the Apache License. Mainly used by developers to maintain present and historic file versions like documentation, source code, and web pages, it primarily aims to be a compatible successor to the extensively used CVS (Concurrent Versions System).

SVN supports several protocols for network access: SVN, SVN+SSH, HTTP, HTTPS. If you are behind a firewall, HTTP-based Subversion is advantageous since SVN traffic will go through the firewall without any additional firewall rule setting.

 nano /etc/httpd/conf.d/subversion.conf

LoadModule dav_svn_module     modules/mod_dav_svn.so
LoadModule authz_svn_module   modules/mod_authz_svn.so

<Location /svn>
   DAV svn
   SVNParentPath /var/www/svn
   AuthType Basic
   AuthName "Subversion User Authentication "
   AuthUserFile /etc/svn-users
   Require valid-user
</Location>

cd /var/www/svn
svnadmin create testrepo
chown -R apache.apache testrepo

If you still have issues with SELinux Security please apply this:

chcon -R -t httpd_sys_content_t /var/www/svn/testrepo
chcon -R -t httpd_sys_rw_content_t /var/www/svn/testrepo

Step 5. Restart your web server.

 systemctl restart httpd.service

Step 6. Finally, You can visit the url http://your-ip-address/svn/testrepo to check out the content, you will be asked to enter the user name and password.

Step 7. Create basic repository structure with the below commands.

How To Install Apache Tomcat 8 on CentOS

Apache Tomcat is an open source web server and servlet container developed by the Apache Software Foundation. It implements the Java Servlet, JavaServer Pages (JSP), Java Unified Expression Language and Java WebSocket specifications from Sun Microsystems and provides a web server environment for Java code to run in. This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS.

Install Apache Tomcat 8 on CentOS

Step 1. JAVA is the first requirement of Tomcat installation.

CentOS 32 bit:

wget --no-cookies \
--no-check-certificate \
--header "Cookie: oraclelicense=accept-securebackup-cookie" \
"http://download.oracle.com/otn-pub/java/jdk/8u5-b13/jdk-8u5-linux-i586.rpm" \
-O /opt/jdk-8-linux-i586.rpm

 rpm -Uvh /opt/jdk-8-linux-i586.rpm

CentOS 64 bit:

wget --no-cookies \
--no-check-certificate \
--header "Cookie: oraclelicense=accept-securebackup-cookie" \
"http://download.oracle.com/otn-pub/java/jdk/8u5-b13/jdk-8u5-linux-x64.rpm" \
-O /opt/jdk-8-linux-x64.rpm

 rpm -Uvh /opt/jdk-8-linux-x64.rpm

Next, configure newly installed JAVA 8 files using command ‘alternatives‘, run the following series of commands on the terminal to configure Java.

# alternatives --install /usr/bin/java java /usr/java/jdk1.8.0_05/jre/bin/java 20000
# alternatives --install /usr/bin/jar jar /usr/java/jdk1.8.0_05/bin/jar 20000
# alternatives --install /usr/bin/javac javac /usr/java/jdk1.8.0_05/bin/javac 20000
# alternatives --install /usr/bin/javaws javaws /usr/java/jdk1.8.0_05/jre/bin/javaws 20000
# alternatives --set java /usr/java/jdk1.8.0_05/jre/bin/java
# alternatives --set javaws /usr/java/jdk1.8.0_05/jre/bin/javaws
# alternatives --set javac /usr/java/jdk1.8.0_05/bin/javac
# alternatives --set jar /usr/java/jdk1.8.0_05/bin/jar

You can also verify it, by issuing the following command.

 java -version

Step 2. Download and extract Tomcat archive.

Once installing and configuring JAVA on the system, now it’s time to download latest version of Apache Tomcat.

cd /opt
wget http://www.apache.org/dist/tomcat/tomcat-8/v8.0.33/bin/apache-tomcat-8.0.33.tar.gz
tar -xvf pache-tomcat-8.0.21.tar.gz

Step 3. Add tomcat user and group.

ln -s /opt/apache-tomcat-8.0.21 /opt/tomcat-latest
chown -hR tomcat8: /opt/tomcat-latest /opt/apache-tomcat-8.0.21

Step 4. Configure Tomcat to run as a service.

cd /opt/apache-tomcat-8.0.21/bin
./startup.sh

You will get the following output.

Using CATALINA_BASE:   /var/local/apache-tomcat-8.0.21
Using CATALINA_HOME:   /var/local/apache-tomcat-8.0.21
Using CATALINA_TMPDIR: /var/local/apache-tomcat-8.0.21/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /var/local/apache-tomcat-8.0.21/bin/bootstrap.jar:/var/local/apache-tomcat-8.0.21/bin/tomcat-juli.jar
Tomcat started.

You can verify the service running, by default tomcat runs on port no 8080.

[root@server ~]# netstat -antup | grep 8080
tcp        0      0 0.0.0.0:8080                0.0.0.0:*                   LISTEN

Step 5. Finally, open Tomcat from your browser, go to your IP or domain with the 8080 port (because Tomcat will always run on the 8080 port) as an example: mydomain.com:8080, replace mydomain.com with your IP or domain.

To shutdown Tomcat you can simply run the shutdown script in the same folder like this:

 /opt/apache-tomcat-8.0.21/bin/shutdown.sh

Step 6. Setup user accounts.

Configure Tomcat users so they can access admin/manager sections. You can do this by adding the users in the conf/tomcat-users.xml file with your favorite text editor. Add this text to the file:

 nano /opt/apache-tomcat-8.0.21/conf/server.xml

Place the following two lines just above the last line.

<!-- user manager can access only manager section -->
<role rolename="manager-gui" />
<user username="manager" password="_SECRET_PASSWORD_" roles="manager-gui" />

<!-- user admin can access manager and admin section both -->
<role rolename="admin-gui" />
<user username="admin" password="_SECRET_PASSWORD_" roles="manager-gui,admin-gui" />

Congratulation’s! You have successfully Apache Tomcat. Thanks for using this tutorial for installing Apache Tomcat 8 on CentOS system. For additional help or useful information, we recommend you to check the official Apache Tomcat web site.

How To Install phpMyAdmin on Nginx

PhpMyaAdmin is the web based administration tool for managing the MySQL, MariaDB and Drizzle servers, it helps in performing databases activities such as creating, deleting ,querying , tables, columns, relations, indexes, users, permissions, etc. This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS and asume and that you already have Nginx installed on the system. You will also need php-fpm to have phpmyadmin working on Nginx.

In this tutorial we will show you how to install and configuration of phpMyaAdmin on Nginx web server on your CentOS 6 server.

Install phpMyAdmin on Nginx

Step 1. First add EPEL yum repository your system.

CentOS 6:

 rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

CentOS 7:

 rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-1.noarch.rpm

Step 2. Install phpMyAdmin using the following command.

 yum -y install phpmyadmin php

Step 3. Configure nginx to serve phpMyAdmin.

In Nginx, virtual host file can be found in /etc/nginx/conf.d directory. Lets create file called “phpmyadmin.conf”.

#nano /etc/nginx/conf.d/phpmyadmin.wpcademy.com.conf

server {
listen   80;
server_name phpmyadmin.wpcademy.com;
root /var/www/html/phpMyAdmin;
 
location / {
index  index.php;
}
 
## Images and static content is treated different
location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ {
access_log        off;
expires           30d;
}
 
location ~ /\.ht {
deny  all;
}
 
location ~ /(libraries|setup/frames|setup/libs) {
deny all;
return 404;
}
 
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/html/phpMyAdmin$fastcgi_script_name;
}
}

Create required directory and enable Nginx virtual host for phpmyadmin.

 mkdir -p /var/www/html/phpMyAdmin

Step 4. Restart the services.

service nginx restart
service php-fpm restart

Step 5. Finally, test phpMyAdmin.

Now open your browser and surf to http://youripaddress/phpMyAdmin or http://yourdomin.com/phpMyAdmin and your phpmyadmin will ask you for user and password of your mysql installation, you can use root as user and the root mysql password, or any other mysql user/password.
