== Install PHP 8.1 Remi Repository ==

36

37

Currently, PHP 8.1 is not featured in Rocky Linux’s AppStream, given it’s still relatively new and hasn’t filtered down the chain in Rhel’s repositories yet. However, you can install PHP from (Remi) repository, a free-to-use third-party repository that deploys the latest PHP 8.1 builds.

38

39

The first task is to install the **(EPEL**) repository, which stands for (**Extra Packages for Enterprise Linux). **For newer users to Rhel and Rocky Linux, EPEL contains the most commonly used software packages for Enterprise Linux.

40

41

To install EPEL, use the following **(dnf)** terminal command:

42

43

{{{sudo dnf install epel-release}}}

//Example output~://

[[[[image:https://www.linuxcapable.com/wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2021/11/install-epel-release-rocky-linux-8-for-php-8.1.png.webp||alt="How to Install PHP 8.1 on Rocky Linux 8" height="337" width="734"]]>>url:https://www.linuxcapable.com/wp-content/uploads/2021/11/install-epel-release-rocky-linux-8-for-php-8.1.png]]

48

49

Type **“Y,”** then press the **“ENTER KEY”** to proceed with the installation.

50

51

Now that you have added the EPEL repository, enable** (Remi repository) **with the following:

52

53

{{{sudo dnf install dnf-utils http://rpms.remirepo.net/enterprise/remi-release-8.rpm}}}

//Example output~://

[[[[image:https://www.linuxcapable.com/wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2021/11/install-php-8.1-on-rocky-linux-8-import-remi-repository.png.webp||alt="How to Install PHP 8.1 on Rocky Linux 8" height="445" width="734"]]>>url:https://www.linuxcapable.com/wp-content/uploads/2021/11/install-php-8.1-on-rocky-linux-8-import-remi-repository.png]]

58

59

Type **“Y,”** then press the **“ENTER KEY”** to proceed with the installation.

60

61

Next, use the **(dnf)** command to update your repository list:

62

63

{{{sudo dnf update}}}

64

65

You will notice a query in your terminal about importing the **(GPG key)** for the Remi repository.

//Example~://

[[[[image:https://www.linuxcapable.com/wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2021/11/import-gpg-key-rocky-linux-8-remi-repository-for-php-8.1.png.webp||alt="How to Install PHP 8.1 on Rocky Linux 8" height="211" width="734"]]>>url:https://www.linuxcapable.com/wp-content/uploads/2021/11/import-gpg-key-rocky-linux-8-remi-repository-for-php-8.1.png]]

70

71

Type **“Y,” **then press the **“ENTER KEY”** to proceed with importing the GPG key and completing the installation.

72

73

Note, you will be prompt **x2 **more times to type **“Y”** to import more GPG keys. This is fine to do.

74

75

== Enable PHP 8.1 (Remi) Repository ==

76

77

PHP 7.2 is the default PHP choice for standard installation on Rhel/Rocky Linux with Remi’s repository. A quick tip is to use the **(list php) **command to see the options available and the default.

78

79

The following dnf module list command can do this:

80

81

{{{sudo dnf module list php}}}

82

83

You will get the following output as below. Note the **(d)** tag for default PHP to be installed:

84

85

[[[[image:https://www.linuxcapable.com/wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2021/11/remi-module-list-php-8.1-select-example-rocky-linux-8.png.webp||alt="How to Install PHP 8.1 on Rocky Linux 8" height="391" width="734"]]>>url:https://www.linuxcapable.com/wp-content/uploads/2021/11/remi-module-list-php-8.1-select-example-rocky-linux-8.png]]

86

87

As you can see above, the **(d)** tag is next to PHP 7.2, which you will need to reset and change to install PHP 8.1 on Rocky Linux.

88

89

To reset the PHP list is easy with the following command:

90

91

{{{sudo dnf module list reset php}}}

92

93

Next, enable PHP 8.1 with the following command:

94

95

{{{sudo dnf module enable php:remi-8.1}}}

//Example output~://

[[[[image:https://www.linuxcapable.com/wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2021/11/set-php-8.1-remi-repository-default-rocky-linux-8.png.webp||alt="How to Install PHP 8.1 on Rocky Linux 8" height="301" width="734"]]>>url:https://www.linuxcapable.com/wp-content/uploads/2021/11/set-php-8.1-remi-repository-default-rocky-linux-8.png]]

100

101

== Install PHP 8.1 ==

102

103

Now that you have added the Remi PHP repository and enabled PHP 8.1 to be the default version on your Rocky Linux system, you can install PHP 8.1 with the following command:

104

105

{{{sudo dnf install php}}}

//Example output~://

[[[[image:https://www.linuxcapable.com/wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2021/11/install-php-8.1-on-rocky-linux-8.png.webp||alt="How to Install PHP 8.1 on Rocky Linux 8" height="733" width="734"]]>>url:https://www.linuxcapable.com/wp-content/uploads/2021/11/install-php-8.1-on-rocky-linux-8.png]]

110

111

Type **“Y,”** then press the **“ENTER KEY”** to proceed with the installation.

112

113

Note, you will be prompted for more GPG key imports.

114

115

If you would like to install the most commonly used extensions for PHP 8.1, use the following command:

116

117

{{{sudo dnf install php-cli php-fpm php-curl php-mysqlnd php-gd php-opcache php-zip php-intl php-common php-bcmath php-imap php-imagick php-xmlrpc php-json php-readline php-memcached php-redis php-mbstring php-apcu php-xml}}}

118

119

Note, remove the options you do not want this is optional.

//Example output~://

[[[[image:https://www.linuxcapable.com/wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2021/11/install-extra-php-8.1-extensions-rocky-linux-8.1.png.webp||alt="How to Install PHP 8.1 on Rocky Linux 8" height="733" width="734"]]>>url:https://www.linuxcapable.com/wp-content/uploads/2021/11/install-extra-php-8.1-extensions-rocky-linux-8.1.png]]

124

125

Type **“Y,”** then press the **“ENTER KEY”** to proceed with the installation.

126

127

Now that you have installed PHP 8.1 and the extensions, check the version with the following command:

{{{php -v}}}

//Example output~://

[[[[image:https://www.linuxcapable.com/wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2021/11/php-8.1-version-command-example-rocky-linux-8.png.webp||alt="How to Install PHP 8.1 on Rocky Linux 8" height="175" width="734"]]>>url:https://www.linuxcapable.com/wp-content/uploads/2021/11/php-8.1-version-command-example-rocky-linux-8.png]]

134

135

== PHP-FPM Installations of PHP 8.1 ==

136

137

Unlike PHP-FPM installations on Debian/Ubuntu that use the** (www-data) **user, this isn’t the case with RHEL family installations. By default on AlmaLinux, the PHP-FPM service is designed to be run **(Apache)** user, which is incorrect since we are using Nginx, and this needed to be corrected.

138

139

Firstly, open following **(www.conf) **configuration file:

140

141

{{{sudo nano /etc/php-fpm.d/www.conf}}}

142

143

Next, replace the **(Apache) **user and group with the **(Nginx)** user and group:

144

145

[[[[image:https://www.linuxcapable.com/wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2021/09/remove-apache-from-www.conf-lemp-install-php-fpm-almalinux.png.webp||alt="How to Install PHP 8.0 on Rocky Linux 8" height="229" width="734"]]>>url:https://www.linuxcapable.com/wp-content/uploads/2021/09/remove-apache-from-www.conf-lemp-install-php-fpm-almalinux.png]]

146

147

To save, press **(CTRL+O) **then exit **(CTRL+X)**.

148

149

Now you will too reload or restart your PHP-FPM service:

150

151

{{{sudo systemctl restart php-fpm}}}

152

153

=== Nginx Configurement ===

154

155

The Nginx server block needs the following example below for Nginx to process the PHP files.

156

157

Below, example for all server blocks that process PHP files that need the **location ~~ .php$** added.

{{{server {

# … some other code

# Pass the php scripts to FastCGI server specified in upstream declaration.

162

location ~ \.php(/|$) {

163

include fastcgi.conf;

164

fastcgi_pass unix:/run/php-fpm/www.sock;

165

fastcgi_split_path_info ^(.+\.php)(/.*)$;

166

fastcgi_param PATH_INFO $fastcgi_path_info;

167

fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;

168

fastcgi_param DOCUMENT_ROOT $realpath_root;

169

try_files $uri $uri/ /app.php$is_args$args;

170

fastcgi_intercept_errors on;

}

}}}}

Test Nginx to make sure you have no errors with the adjustments made with the code above; enter the following.

{{{sudo nginx -t}}}

//Example output~://

{{{nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

181

nginx: configuration file /etc/nginx/nginx.conf test is successful}}}

182

183

Restart Nginx service for installation to be complete.

184

185

{{{sudo systemctl restart nginx}}}

186

187

== Comments and Conclusion ==

188

189

In the tutorial, you have learned how to install PHP 8.1 and configure how to use it with Apache and Nginx. PHP 8.1 is exciting. However, at the current moment, it is still coming out of beta and not considered stable, such as 8.0 or the old stable 7.4, so beware you may find that many of your favorite software like WordPress or Plugins/Themes for CMS software may conflict until developers can update.

190

191

Do some research, prepare, and have PHP 7.4 or 8.0 installed and ready to replace if anything goes wrong when making the switch. The stable versions such as 8.0 are still actively developed, and packages are pushed simultaneously along with the 8.1 packages.
