ENVIRONMENT VARIABLES

Many parts of Mojolicious can be tuned with environment variables. Debug environment variables are excluded because they are for developer use only.

MOJO_APP

Decides which Mojolicious or Mojo application will be used, should always contain a class name like MyApp, usually defaults to Mojo::HelloWorld.

    MOJO_APP=MyApp

MOJO_CA_FILE

The path to the TLS CA authority file, should always contain a path like /etc/tls/cacerts.pem. Note that IO::Socket::SSL must be installed for TLS support.

    MOJO_CA_FILE=/etc/tls/cacerts.pem

MOJO_CHUNK_SIZE

Chunk size used for IO operations in bytes, a bigger chunk size speeds up IO operations but will also use more memory, defaults to 262144.

    MOJO_CHUNK_SIZE=1024

MOJO_DNS_SERVER

DNS server to use for non-blocking lookups.

    MOJO_DNS_SERVER=8.8.8.8

MOJO_EPOLL

Force epoll mainloop for IO operations. Note that IO::Epoll must be installed for epoll support.

    MOJO_EPOLL=1

MOJO_HOME

Home directory for the Mojolicious application, should always contain a path like /home/sri/myapp.

    MOJO_HOME=/home/sri/myapp

MOJO_KQUEUE

Force kqueue mainloop for IO operations. Note that IO::KQueue must be installed for kqueue support.

    MOJO_KQUEUE=1

MOJO_LOG_LEVEL

Log level for the Mojolicious application, should contain a valid log level like debug or error.

    MOJO_LOG_LEVEL=debug
    MOJO_LOG_LEVEL=error

MOJO_MAX_LINE_SIZE

Maximum line size for HTTP message start lines and headers in bytes, defaults to 10240.

    MOJO_MAX_LINE_SIZE=2048

MOJO_MAX_MEMORY_SIZE

Maximum size in bytes for HTTP content to keep in memory, bigger content will be written to temporary files, defaults to 262144.

    MOJO_MAX_MEMORY_SIZE=2048

MOJO_MAX_MESSAGE_SIZE

Maximum size for HTTP messages in bytes, defaults to 5242880.

    MOJO_MAX_MESSAGE_SIZE=1024

MOJO_MAX_REDIRECTS

    MOJO_MAX_REDIRECTS=3

Maximum number of redirects Mojo::Client will follow, defaults to 0.

MOJO_MODE

Run mode for the Mojolicious application, should contain a valid mode like development or production.

    MOJO_MODE=development
    MOJO_MODE=production

MOJO_NO_BONJOUR

Disable Bonjour support. Note that Net::Rendezvous::Publish must be installed for Bonjour support.
