-WebTry Server |
-============= |
- |
-Allows trying out Skia code in the browser. Run a local webserver |
-and from the pages it serves try out Skia code and see the results |
-immediately. |
- |
- |
-Running Locally |
-=============== |
- |
-One time setup: |
- |
- $ export SKIA_ROOT=path_to_your_skia_source |
- $ export WEBTRY_INOUT=path_to_a_writeable_directory |
- $ mkdir -p $WEBTRY_INOUT |
- |
-Then, to run: |
- |
- $ cd experimental/webtry |
- $ go get -d |
- $ ./build |
- $ ./webtry |
- |
-Then visit http://localhost:8000 in your browser. |
- |
-Only tested under linux and MacOS, doubtful it will work on other platforms. |
- |
- |
-Server Setup |
-============ |
- |
-Create a GCE instance: |
- |
- gcutil --project=google.com:skia-buildbots addinstance skia-webtry-b \ |
- --zone=us-central2-b --external_ip_address=108.170.220.126 \ |
- --service_account=default \ |
- --service_account_scopes="https://www.googleapis.com/auth/devstorage.full_control" \ |
- --network=default --machine_type=n1-standard-1 --image=backports-debian-7-wheezy-v20140331 \ |
- --persistent_boot_disk |
- |
-Make sure port 80 is accessible externally for the above instance. |
- |
-SSH into the instance: |
- |
- gcutil --project=google.com:skia-buildbots ssh --ssh_user=default skia-webtry-b |
- |
- |
-Do the first time |
-================= |
- |
-The following things only need to be done once. |
- |
-1. SSH into the server as default. |
-2. sudo apt-get install git |
-3. git clone https://skia.googlesource.com/skia |
-4. cd ~/skia/experimental/webtry/setup |
-5. ./webtry_setup.sh |
- |
-6. Add the following to the /etc/schroot/minimal/fstab: |
- |
- none /run/shm tmpfs rw,nosuid,nodev,noexec 0 0 |
- /home/webtry/inout /skia_build/inout none rw,bind 0 0 |
- /home/webtry/cache /skia_build/cache none rw,bind 0 0 |
- |
-7. Change /etc/monit/monitrc to: |
- |
- set daemon 2 |
- |
-then run the following so it applies: |
- |
- sudo /etc/init.d/monit restart |
- |
-This means that monit will poll every two seconds that our application is up and running. |
- |
-8. Set the TCP keepalive. For more info see: |
- https://developers.google.com/cloud-sql/docs/gce-access |
- |
- sudo sh -c 'echo 60 > /proc/sys/net/ipv4/tcp_keepalive_time' |
- |
- |
-To update the code |
-================== |
- |
-1. SSH into the server as default. |
-2. cd ~/skia/experimental/webtry/setup |
-3. git pull |
-4. ./webtry_setup.sh |
- |
- |
