| 1 WebTry Server | |
| 2 ============= | |
| 3 | |
| 4 Allows trying out Skia code in the browser. Run a local webserver | |
| 5 and from the pages it serves try out Skia code and see the results | |
| 6 immediately. | |
| 7 | |
| 8 | |
| 9 Running Locally | |
| 10 =============== | |
| 11 | |
| 12 One time setup: | |
| 13 | |
| 14 $ export SKIA_ROOT=path_to_your_skia_source | |
| 15 $ export WEBTRY_INOUT=path_to_a_writeable_directory | |
| 16 $ mkdir -p $WEBTRY_INOUT | |
| 17 | |
| 18 Then, to run: | |
| 19 | |
| 20 $ cd experimental/webtry | |
| 21 $ go get -d | |
| 22 $ ./build | |
| 23 $ ./webtry | |
| 24 | |
| 25 Then visit http://localhost:8000 in your browser. | |
| 26 | |
| 27 Only tested under linux and MacOS, doubtful it will work on other platforms. | |
| 28 | |
| 29 | |
| 30 Server Setup | |
| 31 ============ | |
| 32 | |
| 33 Create a GCE instance: | |
| 34 | |
| 35 gcutil --project=google.com:skia-buildbots addinstance skia-webtry-b \ | |
| 36 --zone=us-central2-b --external_ip_address=108.170.220.126 \ | |
| 37 --service_account=default \ | |
| 38 --service_account_scopes="https://www.googleapis.com/auth/devstorage.full_
control" \ | |
| 39 --network=default --machine_type=n1-standard-1 --image=backports-debian-7-
wheezy-v20140331 \ | |
| 40 --persistent_boot_disk | |
| 41 | |
| 42 Make sure port 80 is accessible externally for the above instance. | |
| 43 | |
| 44 SSH into the instance: | |
| 45 | |
| 46 gcutil --project=google.com:skia-buildbots ssh --ssh_user=default skia-webtr
y-b | |
| 47 | |
| 48 | |
| 49 Do the first time | |
| 50 ================= | |
| 51 | |
| 52 The following things only need to be done once. | |
| 53 | |
| 54 1. SSH into the server as default. | |
| 55 2. sudo apt-get install git | |
| 56 3. git clone https://skia.googlesource.com/skia | |
| 57 4. cd ~/skia/experimental/webtry/setup | |
| 58 5. ./webtry_setup.sh | |
| 59 | |
| 60 6. Add the following to the /etc/schroot/minimal/fstab: | |
| 61 | |
| 62 none /run/shm tmpfs rw,nosuid,nodev,noexec 0 0 | |
| 63 /home/webtry/inout /skia_build/inout none rw,bind 0
0 | |
| 64 /home/webtry/cache /skia_build/cache none rw,bind 0
0 | |
| 65 | |
| 66 7. Change /etc/monit/monitrc to: | |
| 67 | |
| 68 set daemon 2 | |
| 69 | |
| 70 then run the following so it applies: | |
| 71 | |
| 72 sudo /etc/init.d/monit restart | |
| 73 | |
| 74 This means that monit will poll every two seconds that our application is up and
running. | |
| 75 | |
| 76 8. Set the TCP keepalive. For more info see: | |
| 77 https://developers.google.com/cloud-sql/docs/gce-access | |
| 78 | |
| 79 sudo sh -c 'echo 60 > /proc/sys/net/ipv4/tcp_keepalive_time' | |
| 80 | |
| 81 | |
| 82 To update the code | |
| 83 ================== | |
| 84 | |
| 85 1. SSH into the server as default. | |
| 86 2. cd ~/skia/experimental/webtry/setup | |
| 87 3. git pull | |
| 88 4. ./webtry_setup.sh | |
| 89 | |
| 90 | |
| 91 Third Party Code | |
| 92 ================ | |
| 93 | |
| 94 * res/js/polyfill.js - Various JS polyfill libraries. To rebuild or update | |
| 95 see poly/README.md. | |
