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 includes its own copy of LibreSSL, otherwise it tries to use the default system libraries, like PCRE, etc.

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
• 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
