| 28 |
|
| 29 | ## Using |
| 30 |
|
| 31 | 1. Copy this directory with its scripts to a place OpenResty/nginx workers have |
| 32 | access, such as `/srv/[SITE]/resty-gitweb`. (In reality it doesn't matter |
| 33 | where, as long as it's accessible.) |
| 34 |
|
| 35 | 2. Copy your config file (`resty-gitweb.yaml`) to |
| 36 | `/etc/[SITE]/resty-gitweb.yaml` (or somewhere else) |
| 37 |
|
| 38 | 3. Add the following near the top (`main` context, outside of any blocks) of |
| 39 | your OpenResty/nginx configuration file: |
| 40 |
|
| 41 | ``` |
| 42 | # resty-gitweb configuration |
| 43 | env RESTY_GITWEB; # Script won't run without this |
| 44 | env RESTY_GITWEB_ENV=PROD; # PROD for Production, DEV for Development. DEV by default. |
| 45 | env RESTY_GITWEB_CONFIG=/etc/[SITE]/resty-gitweb.yaml; # Wherever you put your configuration file |
| 46 | ``` |
| 47 |
|
| 48 | 4. Add the following to the `http` block in your OpenResty/nginx configuration |
| 49 | file: |
| 50 |
|
| 51 | ``` |
| 52 | lua_package_path "/usr/local/lib/lua/5.1;/srv/[SITE]/resty-gitweb/?.lua;;"; # Add resty-gitweb to your Lua package path |
| 53 | init_by_lua_file /srv/[SITE]/resty-gitweb/init.lua; # Initialize modules for nginx workers |
| 54 | ``` |
| 55 |
|
| 56 | 5. And in whichever `location` block you wish to serve content: |
| 57 |
|
| 58 | ``` |
| 59 | content_by_lua_file /srv/[SITE]/resty-gitweb/app.lua; |
| 60 | ``` |
| 61 |
|
| 62 | 6. Reload OpenResty/nginx to update config |
| 63 |
|
| 64 | ## OpenResty or nginx? |
| 65 |
|
| 66 | Note that I use "OpenResty/nginx" instead of just OpenResty; while you can just |
| 67 | install and use the pre-built |
| 68 | [OpenResty](https://openresty.org/en/download.html) package, you could actually |
| 69 | use nginx with only a few added OpenResty components. These are the only |
| 70 | OpenResty components you actually need to |
| 71 | [compile](https://www.nginx.com/resources/wiki/extending/compiling/) to use |
| 72 | this package: |
| 73 |
|
| 74 | #### nginx modules |
| 75 |
|
| 76 | * [lua-nginx-module](https://github.com/openresty/lua-nginx-module) |
| 77 |
|
| 78 | #### Lua libraries |
| 79 |
|
| 80 | (run `sudo make all install LUA_VERSION=5.1` for each) |
| 81 |
|
| 82 | * [lua-resty-core](https://github.com/openresty/lua-resty-core) |
| 83 | * [lua-resty-shell](https://github.com/openresty/lua-resty-shell) |
| 84 | * [lua-resty-lrucache](https://github.com/openresty/lua-resty-lrucache) |
| 85 | * [lua-resty-signal](https://github.com/openresty/lua-resty-signal) |
| 86 | * [lua-tablepool](https://github.com/openresty/lua-tablepool) |
| 87 |
|
| 88 | Note that lua-nginx-module is the only nginx module that needs to be installed |
| 89 | with nginx compatibility. The other dependencies just need to be installed on |
| 90 | your Lua path/cpath. **If you're compiling OpenResty components yourself, you |
| 91 | may need to build them with OpenResty's |
| 92 | [branch](https://github.com/openresty/luajit2) of LuaJIT 2.1.0 instead of the |
| 93 | original.** |
| 94 |
|
| 95 | (The full OpenResty package has far more precompiled OpenResty components, so |
| 96 | you may just want to use that if resty-gitweb isn't the only thing you want to |
| 97 | use OpenResty for.) |
