场景：生产环境部署Open-Falcon-0.2.1监控

部署过程(单机安装)

1. 官方安装文档

http://book.open-falcon.org/zh_0_2/quick_install/

1. 安装redis和mysql

我本机已安装mysql，版本为mysql5.7，这里直接拿来官方的步骤，如你本地已安装，那就忽略此步骤

# yum install -y redis mysql-server

2. 下载falcon-plus.git

# cd /tmp && wget https://github.com/open-falcon/falcon-plus/archive/master.zip
# unzip master.zip
# cd falcon-plus-master/scripts/mysql/db_schema/

3. 初始化数据库

由于安装的是mysql5.7，所以在初始化数据库的时候需要确保mysql用户密码plugin必须是mysql_native_password,低于此版本的应该没问题，不确定的可以自行查看点击我查看方法.

# mysql -u root -p < 1_uic-db-schema.sql
# mysql -u root -p < 2_portal-db-schema.sql
# mysql -u root -p < 3_dashboard-db-schema.sql
# mysql -u root -p < 4_graph-db-schema.sql
# mysql -u root -p < 5_alarms-db-schema.sql

4. 安装go环境

# yum install golang
# mkdir ~/workspace
# echo 'export GOPATH="$HOME/workspace"' >> ~/.bashrc
# source ~/.bashrc

5. 创建工作目录

# export FALCON_HOME=/home/homework
# export WORKSPACE=$FALCON_HOME/open-falcon
# mkdir -p $WORKSPACE

6. 下载二进制包

# mkdir $WORKSPACE && cd !$ && wget https://github.com/open-falcon/falcon-plus/releases/download/v0.2.1/open-falcon-v0.2.1.tar.gz
# tar zxf open-falcon-v0.2.1.tar.gz && rm -rf open-falcon-v0.2.1.tar.gz

7. 修改配置文件

# cd $WORKSPACE
# grep -Ilr 3306  ./ | xargs -n1 -- sed -i 's/root:/用户名:密码/g'

在启动后端前，由于使用mysql5.7，需要在下面模块的配置文件内连接mysql的url加上参数“&allowNativePasswords=true”
falcon-graph
falcon-hbs
falcon-nodata
falcon-aggregator
falcon-api
falcon-alarm

# vim xxxx/config/cfg.json

...
"database": "root:xxxx@tcp(127.0.0.1:3306)/falcon_portal?loc=Local&parseTime=true&allowNativePasswords=true",
...

否则模块无法启动，日志内会出现下面报错

this user requires mysql native password authentication.

8. 启动和检查后端服务

# ./open-falcon start
[falcon-graph] 54107
[falcon-hbs] 54132
[falcon-judge] 26801
[falcon-transfer] 26808
[falcon-nodata] 54159
[falcon-aggregator] 54172
[falcon-agent] 63721
[falcon-gateway] 29834
[falcon-api] 54188
[falcon-alarm] 54197

# ./open-falcon check
        falcon-graph         UP           55800 
          falcon-hbs         UP           55817 
        falcon-judge         UP           55832 
     falcon-transfer         UP           55843 
       falcon-nodata         UP           55853 
   falcon-aggregator         UP           55865 
        falcon-agent         UP           55883 
      falcon-gateway         UP           55895 
          falcon-api         UP           56948 
        falcon-alarm         UP           55972

如果某个模块状态为DOWN，就去查看该模块的log日志，位置是xxx/logs/xxx.log
