Centos7安装 OpenFalcon单机版

准备工作

1.跟新yum源

yum clean all
yum makecache
yum update -y

2.安装git

因为mysql的脚本要么使用git下载，要么上传下载好的【上传可不安装】
yum install -y git

3.安装redis

如果没有装epel，会提示No package redis available，也就是没有安装包可用，因为官方yum和阿里yum可能都没有redis，故只能通过fedora的epel仓库来安装 命令：yum install -y epel-release
安装redis
yum install redis -y
启动redis
systemctl start redis
设置redis开机启动 
systemctl enable redis
可以用下面的语句查看redis是否开启
systemctl status redis

4.安装mysql

因为centos7后系统使用 mariadb 替换了 mysql，所以先卸载mariadb 在安装mysql

卸载mariadb 先查询，在强力删除

rpm -qa | grep mariadb
rpm -e --nodeps mariadb-libs-5.5.50-1.el7_2.x86_64

安装mysql

下载repo源
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
安装该rpm包（安装这个包后，会获得两个mysql的yum repo源：/etc/yum.repos.d/mysql-community.repo，/etc/yum.repos.d/mysql-community-source.repo）
rpm -ivh mysql-community-release-el7-5.noarch.rpm
安装mysql
yum install mysql-server -y
启动mysql
systemctl start mysql
查看mysql是否开启
systemctl status mysql

5.下载

数据库脚本

cd /tmp/ && git clone https://github.com/open-falcon/falcon-plus.git 
cd /tmp/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
rm -rf /tmp/falcon-plus/

下载安装包

wget https://github.com/open-falcon/falcon-plus/archive/master.zip

后台安装

创建工作目录

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

解压二进制包

tar -xzvf open-falcon-v0.2.0.tar.gz -C $WORKSPACE
在一台机器上启动所有的后端组件

启动

cd $WORKSPACE
./open-falcon start

检查所有模块的启动状况

./open-falcon check

更多的命令行工具用法

./open-falcon [start|stop|restart|check|monitor|reload] module
./open-falcon start agent

./open-falcon check

前台安装

创建工作目录

export HOME=/home/work
export WORKSPACE=$HOME/open-falcon
mkdir -p $WORKSPACE
cd $WORKSPACE

克隆前端组件代码

cd $WORKSPACE
git clone https://github.com/open-falcon/dashboard.git

安装依赖包

yum install -y python-virtualenv
yum install -y python-devel
yum install -y openldap-devel
yum install -y mysql-devel
yum groupinstall "Development tools"

cd $WORKSPACE/dashboard/
virtualenv ./env

./env/bin/pip install -r pip_requirements.txt -i https://pypi.douban.com/simple

修改配置

dashboard的配置文件为： 'rrd/config.py'，请根据实际情况修改

API_ADDR 表示后端api组件的地址

API_ADDR = "http://127.0.0.1:8080/api/v1" 

根据实际情况，修改PORTAL_DB_*, 默认用户名为root，默认密码为””

根据实际情况，修改ALARM_DB_*, 默认用户名为root，默认密码为””

在生产环境启动

bash control start

停止dashboard运行

bash control stop

查看日志

bash control tail
