## How to upgrade PHP on RHEL/CentOS from php71 to php72?
## How to upgrade PHP on RHEL/CentOS?
To our knowledge, there is no way to "upgrade" PHP. You'll need to install php72 like you're doing a fresh install
You may try copying your `php71-php.ini` to your php72-directory which may work. We would recommend redoing the config though.
To our knowledge, there is no way to "upgrade" PHP. You'll need to install the new PHP version like you're doing a fresh install.
You may try copying your old `php.ini` to your new PHP config directory which may work. We would recommend redoing the config though.
### Example: Upgrade from PHP 7.2 to 7.3 on CentOS 7
#### Enable repository
```
$ sudo yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm
$ sudo yum-config-manager --enable remi-php73
```
#### Install packages
```
$ sudo yum install -y php73-php php73-php-cli php73-php-fpm php73-php-devel php73-php-mysqlnd php73-php-mbstring php73-php-xml php73-php-bcmath php73-php-opcache php73-php-gd php73-php-pecl-redis4 php73-php-pecl-gnupg php73-php-pear

> Fingerprint: 1ee0 4cce 88a4 ae4a a29a 5df5 004e 6f47 00f9 7f56
> Package : remi-release-7.6-2.el7.remi.noarch (installed)
> From : /etc/pki/rpm-gpg/RPM-GPG-KEY-remi
> Is this ok [y/N]: y
> ```
#### Install required PEAR-modules
```
$ sudo php73-pear channel-update pear.php.net
Updating channel "pear.php.net"
Update of Channel "pear.php.net" succeeded
$ sudo php73-pear install /var/www/MISP/INSTALL/dependencies/Console_CommandLine/package.xml
install ok: channel://pear.php.net/Console_CommandLine-1.2.2
$ sudo php73-pear install /var/www/MISP/INSTALL/dependencies/Crypt_GPG/package.xml
install ok: channel://pear.php.net/Crypt_GPG-1.6.3
```
#### PHP configuration
Edit `/etc/opt/remi/php73/php.ini`:
> ```
> date.timezone = "Europe/Berlin"
> max_execution_time = 300
> memory_limit = 512M
> upload_max_filesize = 50M
> post_max_size = 50M
> ```
#### Switch to PHP 7.3
```
$ sudo systemctl stop rh-php70-php-fpm
$ sudo systemctl start php73-php-fpm
# check if everything's fine
$ sudo systemctl status php73-php-fpm
```
Now check if the MISP web UI is accessible and if the diagnostics page shows any errors.
> The diagnostics page will show "PHP CLI Version (>7.2 recommended): Unknown (Issues determining version)". That's a [known issue](https://github.com/MISP/MISP/issues/2334).
#### Disable/enable services
```
$ sudo systemctl disable rh-php70-php-fpm
Removed symlink /etc/systemd/system/multi-user.target.wants/rh-php70-php-fpm.service.
$ sudo systemctl enable php73-php-fpm
Created symlink from /etc/systemd/system/multi-user.target.wants/php73-php-fpm.service to /usr/lib/systemd/system/php73-php-fpm.service.
