Build from source

before start, please make sure you prepared this:

yum install -y redis
yum install -y mysql-server

NOTE: be sure to check redis and mysql-server have successfully started.

And then

# Please make sure that you have set `$GOPATH` and `$GOROOT` correctly.
# If you have not golang in your host, please follow [https://golang.org/doc/install] to install golang.

mkdir -p $GOPATH/src/github.com/open-falcon
cd $GOPATH/src/github.com/open-falcon
git clone https://github.com/open-falcon/falcon-plus.git

And do not forget to init the database first (if you have not loaded the database schema before)

cd $GOPATH/src/github.com/open-falcon/falcon-plus/scripts/mysql/db_schema/
mysql -h 127.0.0.1 -u root -p < 1_uic-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 2_portal-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 3_dashboard-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 4_graph-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql

Install Frontend Dashboard

Package Management

We use govendor to manage the golang packages. Please install govendor before compilation.

go get -u github.com/kardianos/govendor

Most depended packages are saved under ./vendor dir. If you want to add or update a package, just run govendor fetch xxxx@commitID or govendor fetch [email protected], then you will find the package have been placed in ./vendor correctly.

Package Release

make clean all pack
