setup-openresty

This is just a small bash script for downloading + installing OpenResty.

It will install OpenResty to /opt/openresty-${OPENRESTY_VERSION} (or to a prefix of your choosing). It can use it's own copy of LibreSSL or OpenSSL. For other libraries (like zlib and PCRE), it will use your system libraries.

It also downloads and installs Lua 5.1.5 + LuaRocks into /opt/openresty-${OPENRESTY_VERSION}/luajit. This provides compatibility when installing modules with LuaRocks. For example, the lua-cjson module fails to build with LuaJIT + LuaRocks, which makes it hard to install rocks like Lapis.

If your system has update-alternatives, then it will add /opt/openresty-${OPENRESTY_VERSION}/luajit/bin/lua as an alternative for /usr/bin/lua, and /opt/openresty-${OPENRESTY_VERSION}/luajit/bin/luac as an alternative for usr/bin/luac.

You can pass options to the script to enable/disable features - they mostly follow the OpenResty configure script options, with a few changes:

• You can get pretty sloppy with dashes vs underscores. All these accomplish the same thing
  • --with-http_dav_module
  • --with-http-dav_module
  • --with_http_dav_module
• You can get pretty sloppy about having the _module in your command line, so these also all do the same thing:
  • --with-http_dav
  • --with-http-dav
• There's a few extra options for enabling some 3rd-party nginx modules not included with OpenResty
  • --with-stream-echo -- enables echo in TCP connections
  • --with-rtmp - enables rtmp
  • --with-nchan - enables nchan
  • --with-ngx-lua-ipc - enables ngx_lua_ipc
  • --with-flv - enables ngx-http-flv, a fork of the rtmp module
  • --with-lua-io - enables lua-io-nginx-module
  • --with-ngx-brotli - enables ngx_brotli
• Choosing the SSL implementation can be accomplished a few ways:
  • --use-libressl - (default) use a self-contained LibreSSL build
  • --use-libressl=x.x.x - use a self-contained LibreSSL build, with a specific version
  • --use-openssl - use a self-contained OpenSSL build
  • --use-openssl=x.x.x - use a self-contained OpenSSL build, with a specific version
  • --use-system-ssl - use your default SSL implementation.
• You can also pass --minimal to disable all non-essential modules/features (http is still enabled, though), then use --with-(x) to explicitly enable the features/modules you want
• Alternatively, you can pass --large to enable all the modules/features, except the drizzle, iconv, and postgres modules. You'll still need to use --with-iconv etc to use those.
• --prefix=/some/path - change the prefix from the default /opt/openresty-${OPENRESTY_VERSION} to some other path
• --symlink This will create symlinks under /usr/local/bin for convenience:
  • /usr/local/bin/lua-openresty -> /opt/openresty-${OPENRESTY_VERSION}/luajit/bin/lua
  • /usr/local/bin/luac-openresty -> /opt/openresty-${OPENRESTY_VERSION}/luajit/bin/luac
  • /usr/local/bin/luajit-openresty -> /opt/openresty-${OPENRESTY_VERSION}/luajit/bin/luajit
  • /usr/local/bin/luarocks-openresty -> /opt/openresty-${OPENRESTY_VERSION}/luajit/bin/luarocks
  • /usr/local/bin/openresty -> /opt/openresty-${OPENRESTY_VERSION}/bin/openresty
  • /usr/local/bin/opm -> /opt/openresty-${OPENRESTY_VERSION}/bin/opm
  • /usr/local/bin/resty -> /opt/openresty-${OPENRESTY_VERSION}/bin/resty
  • /usr/local/bin/restydoc -> /opt/openresty-${OPENRESTY_VERSION}/bin/restydoc
  • /usr/local/bin/restydoc-index -> /opt/openresty/bin/restydoc-index
