Update installation dependencies

To set permissions before you install the Magento software:

1. Log in to your Magento server.

2. Use a file manager application provided by your shared hosting provider to verify write permissions are set on the following directories:

   • vendor (Composer or compressed archive installation)
   • app/etc
   • pub/static
   • var
   • Any other static resources

3. If you have command-line access, enter the following commands in the order shown:

   cd <your Magento install dir>
   find var vendor pub/static pub/media app/etc -type f -exec chmod u+w {} \;
   find var vendor pub/static pub/media app/etc -type d -exec chmod u+w {} \;
   chmod u+x bin/magento
   

   Copy

   To optionally enter all commands on one line, enter the following assuming Magento is installed in /var/www/html/magento2:

   cd /var/www/html/magento2 && find var vendor pub/static pub/media app/etc -type f -exec chmod u+w {} \; && find var vendor pub/static pub/media app/etc -type d -exec chmod u+w {} \; && chmod u+x bin/magento
   

   Copy

4. If you haven’t done so already, get the Magento software in one of the following ways:

   • Compressed archive
   • Composer metapackage
   • Clone the repository (contributing developers only)

5. After you have set file system ownership and permissions, continue with any of the following:

   • Command-line installation
   • Setup Wizard installation

Complete the following tasks in the order shown:

• About the shared group
• Step 1: Create the Magento file system owner and give the user a strong password
• Step 2: Find the web server group
• Step 3: Put the Magento file system owner in the web server’s group
• Step 4: Get the Magento software
• Step 5: Set ownership and permissions for the shared group

About the shared group

To enable the web server to write files and directories in the Magento file system but to also maintain ownership by the Magento file system owner, both users must be in the same group. This is necessary so both users can share access to Magento files (including files created using the Magento Admin or other web-based utilities).

This section discusses how to create a new Magento file system owner and put that user in the web server’s group. You can use an existing user account if you wish; we recommend the user have a strong password for security reasons.

Step 1: Create the Magento file system owner and give the user a strong password

This section discusses how to create the Magento file system owner. (Magento file system owner is another term for the command-line user.)

To create a user on CentOS or Ubuntu, enter the following command as a user with root privileges:

adduser <username>

To give the user a password, enter the following command as a user with root privileges:

passwd <username>

Follow the prompts on your screen to create a password for the user.

For example, to create a user named magento_user and give the user a password, enter:

sudo adduser magento_user
sudo passwd magento_user

Step 2: Find the web server user’s group

To find the web server user’s group:

• CentOS: egrep -i '^user|^group' /etc/httpd/conf/httpd.conf

  Typically, the user and group name are both apache

• Ubuntu: ps aux | grep apache to find the apache user, then groups <apache user> to find the group

  Typically, the user name and the group name are both www-data

Step 3: Put the Magento file system owner in the web server’s group

To put the Magento file system owner in the web server’s group (assuming the typical Apache group name for CentOS and Ubuntu), enter the following command as a user with root privileges:

• CentOS: usermod -a -G apache <username>
• Ubuntu: usermod -a -G www-data <username>

For example, to add apache as a secondary group to user magento_user on CentOS:

sudo usermod -a -G apache magento_user

To confirm your Magento user is a member of the web server group, enter the following command:

groups magento_user

The following sample result shows the user’s primary (magento) and secondary (apache) groups.

magento_user : magento_user apache

To complete the task, restart the web server:

• Ubuntu: service apache2 restart
• CentOS: service httpd restart

Step 4: Get the Magento software

If you haven’t done so already, get the Magento software in one of the following ways:

• Compressed archive
• Composer metapackage
• Clone the repository (contributing developers only)

Step 5: Set ownership and permissions for the shared group

To set ownership and permissions before you install the Magento software:

1. Log in to your Magento server as, or switch to, the Magento file system owner.

2. Enter the following commands in the order shown:

   cd <your Magento install dir>
   find var vendor pub/static pub/media app/etc -type f -exec chmod g+w {} \;
   find var vendor pub/static pub/media app/etc -type d -exec chmod g+ws {} \;
   sudo chown -R :<web server group> .
   chmod u+x bin/magento
   

   Copy

cd /var/www/html/magento2 && find var vendor pub/static pub/media app/etc -type f -exec chmod g+w {} \; && find var vendor pub/static pub/media app/etc -type d -exec chmod g+ws {} \; && chown -R :apache . && chmod u+x bin/magento

cd /var/www/html/magento2 && sudo find var vendor pub/static pub/media app/etc -type f -exec chmod g+w {} \; && sudo find var vendor pub/static pub/media app/etc -type d -exec chmod g+ws {} \; && sudo chown -R :apache . && sudo chmod u+x bin/magento
