Minimum server and PHP requirements

Always use a supported PHP version for your Magento release. Running on unsupported versions:

• Causes fatal errors and broken functionality
• Creates security vulnerabilities
• Voids support eligibility

These extensions must be installed and enabled:

bcmath
ctype
curl
dom
fileinfo
filter
gd
hash
iconv
intl
json
libxml
mbstring
openssl
pcre
pdo_mysql
simplexml
soap
sockets
sodium
spl
tokenizer
xmlwriter
xsl
zip
zlib

Check installed extensions:

php -m

Recommended php.ini settings:

memory_limit = 2G
max_execution_time = 18000
max_input_vars = 10000
post_max_size = 64M
upload_max_filesize = 64M
realpath_cache_size = 10M
realpath_cache_ttl = 7200
opcache.enable = 1
opcache.memory_consumption = 512
opcache.max_accelerated_files = 60000
opcache.validate_timestamps = 0

Note: Set opcache.validate_timestamps = 1 in development for file change detection.
