2，安装依赖

redis安装

# apt-get install redis-server -y

redis-server运行redis

# redis-server
18635:C 27 Nov 22:56:46.506 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
18635:C 27 Nov 22:56:46.506 # Redis version=4.0.9, bits=64, commit=00000000, modified=0, pid=18635, just started
18635:C 27 Nov 22:56:46.506 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
18635:M 27 Nov 22:56:46.508 * Increased maximum number of open files to 10032 (it was originally set to 1024).
18635:M 27 Nov 22:56:46.509 # Creating Server TCP listening socket *:6379: bind: Address already in use

redis成功启动

# redis-cli
127.0.0.1:6379> ping
PONG

mysql安装

# apt-get install mysql-server -y

mysql服务运行

# systemctl status mysql.service

# mysql -u root

mysql> show databases;
mysql> use mysql;
mysql> show tables;
mysql> select User,Host,plugin from user;
+------------------+-----------+-----------------------+
| User             | Host      | plugin                |
+------------------+-----------+-----------------------+
| root             | localhost | auth_socket           |
| mysql.session    | localhost | mysql_native_password |
| mysql.sys        | localhost | mysql_native_password |
| debian-sys-maint | localhost | mysql_native_password |
+------------------+-----------+-----------------------+
mysql> update user set plugin='mysql_native_password' where User='root';
mysql> FLUSH PRIVILEGES;
mysql> exit

# mkdir -p $GOPATH/src/github.com/open-falcon
# cd $GOPATH/src/github.com/open-falcon
# git clone git@github.com:open-falcon/falcon-plus.git# git clone https://github.com/open-falcon/falcon-plus.git# cd falcon-plus/scripts/mysql/db_schema/

不用设置密码回车就行

# mysql -h 127.0.0.1 -u root -p < 1_uic-db-schema.sql
Enter password:
# mysql -h 127.0.0.1 -u root -p < 2_portal-db-schema.sql
Enter password:mysql -h 127.0.0.1 -u root -p < 3_dashboard-db-schema.sql

Enter password:mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql
Enter password:

3，编译

# cd $GOPATH/src/github.com/open-falcon/falcon-plus/
# apt install make -y
# apt install gcc -y
# make all
# make agent
go build -ldflags "-X main.BinaryName=agent -X main.GitCommit=`git rev-parse --short HEAD` -X main.Version=0.3.x" -o bin/agent/falcon-agent ./modules/agentmake pack
go build -ldflags "-X main.BinaryName=Open-Falcon -X main.GitCommit=`git rev-parse --short HEAD` -X main.Version=0.3.x" -o open-falcon
tar -C out -zcf open-falcon-v0.3.x.tar.gz .

# mkdir /root/open-falcon
# tar -zxvf open-falcon-v0.3.x.tar.gz -C /root/open-falcon/

3，运行

启动所有的后端组件./open-falcon start

# ./open-falcon start
[falcon-graph] 9065
[falcon-hbs] 9081
[falcon-judge] 9095
[falcon-transfer] 9105
[falcon-nodata] 9116
[falcon-aggregator] 9127
[falcon-agent] 9140
[falcon-gateway] 9155
[falcon-api] 9165
[falcon-alarm] 9181

检查模块启动情况

# ./open-falcon checkfalcon-graph         UP            9065falcon-hbs         UP            9081falcon-judge         UP            9095falcon-transfer         UP            9105falcon-nodata         UP            9116falcon-aggregator         UP            9127falcon-agent         UP            9140falcon-gateway         UP            9155falcon-api         UP            9165falcon-alarm         UP            9181

4，安装前端

# pwd
/root/open-falcon
# git clone git@github.com:open-falcon/dashboard.git# git clone https://github.com/open-falcon/dashboard.git# apt install -y python-virtualenv slapd ldap-utils libmysqld-dev build-essential python-dev libldap2-dev libsasl2-dev libssl-dev

# pwd
/root/open-falcon/dashboard
# virtualenv ./env
Running virtualenv with interpreter /usr/bin/python2
New python executable in /root/open-falcon/dashboard/env/bin/python2
Also creating executable in /root/open-falcon/dashboard/env/bin/python# ./env/bin/pip install -r pip_requirements.txt -i https://pypi.douban.com/simple
# ./env/bin/pip install -r pip_requirements.txt

配置文件

# cat rrd/config.py

生产环境启动bash control start

# bash control start
falcon-dashboard started..., pid=15164

# bash control stop

查看日志bash control tail

# bash control tail

[2019-11-28 17:21:25 +0000] [15172] [INFO] Booting worker with pid: 15172

5，数据库连接报错

查看日志

# tail /root/open-falcon/nodata/logs/nodata.log
db.go:38: config.InitDB error Error 1045: Access denied for user 'real_user'@'localhost' (using password: YES)

real_user:real_password替换为root:
服务器登陆用户名为root，密码为空

grep -ilr real_user:real_password | xargs -n1 -- sed -i 's/real_user:real_password/root:/g'

6，设置环境变量

# echo 'export PATH=$PATH:/root/open-falcon' >> .bashrc
# source .bashrc
# which open-falcon
/root/open-falcon/open-falcon

# open-falcon checkfalcon-graph         UP            3769falcon-hbs         UP            3784falcon-judge         UP            3797falcon-transfer         UP            3807falcon-nodata         UP            3818falcon-aggregator         UP            3828falcon-agent         UP            3840falcon-gateway         UP            3855falcon-api         UP            3866falcon-alarm         UP            3883

7，安装问题,不要安装编译版本，要安装二进制版本

# ./open-falcon checkfalcon-graph       DOWN               -falcon-hbs       DOWN               -falcon-judge       DOWN               -falcon-transfer       DOWN               -falcon-nodata       DOWN               -falcon-aggregator       DOWN               -falcon-agent       DOWN               -falcon-gateway       DOWN               -falcon-api       DOWN               -falcon-alarm       DOWN               -

ERROR

# ./open-falcon start
expect config file: graph/config/cfg.json

# pwd
/root/go/src/github.com/open-falcon/falcon-plus/modules/graph
# cp cfg.example.json cfg.json

cfg.example.json 配置文件都改为 cfg.json

pwd
/root/go/src/github.com/open-falcon/falcon-plus/modules
# ls
agent  aggregator  alarm  api  gateway  graph  hbs  judge  nodata  transfer

8，设置环境变量

# echo 'export PATH=$PATH:/root/go/src/github.com/open-falcon/falcon-plus' >> /root/.bashrc
# source /root/.bashrc
# which open-falcon
/root/go/src/github.com/open-falcon/falcon-plus/open-falcon
