Starting the web interface

go install github.com/google/zoekt/cmd/zoekt-webserver
$GOPATH/bin/zoekt-webserver -listen :6070

A more organized installation on a Linux server should use a systemd unit file, eg.

[Unit]
Description=zoekt webserver

[Service]
ExecStart=/zoekt/bin/zoekt-webserver -index /zoekt/index -listen :443  --ssl_cert /zoekt/etc/cert.pem   --ssl_key /zoekt/etc/key.pem
Restart=always

[Install]
WantedBy=default.target

SEARCH SERVICE

Zoekt comes with a small service management program:

go install github.com/google/zoekt/cmd/zoekt-indexserver

cat << EOF > config.json
[{"GithubUser": "username"},
 {"GithubOrg": "org"},
 {"GitilesURL": "https://gerrit.googlesource.com", "Name": "zoekt" }
]
EOF

$GOPATH/bin/zoekt-server -mirror_config config.json

This will mirror all repos under ‘github.com/username’, ‘github.com/org’, as well as the ‘zoekt’ repository. It will index the repositories.

It takes care of fetching and indexing new data and cleaning up logfiles.

The webserver can be started from a standard service management framework, such as systemd.

SYMBOL SEARCH

It is recommended to install Universal ctags to improve ranking. See here for more information.
