Open-falcon 安装部署手册

搭建环境

OS: RHEL 7.3 
kernel: 3.10.0-514.el7.x86_64

host0: 10.16.112.128 <-> rhel-node01
host1: 10.16.112.253 <-> rhel-node02 
host2: 10.16.112.247 <-> rhel-node03

# 安装epel源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

echo 7 > /etc/yum/vars/releasever

基础环境

安装 go

因为官方yum和阿里yum都没有go的安装包，故只能通过fedora的epel仓库来安装

# yum install -y epel-release
# yum install golang -y

# 验证
# go version
go version go1.8.3 linux/amd64

安装redis

# yum install redis -y

# 开机启动redis
# systemctl enable redis

# 启动redis
# systemctl start redis

# 查看redis状态
# systemctl status redis

安装mysql-server

# 安装mysql源
# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-5.noarch.rpm

# yum install -y mysql-server

# 启动mysql
# systemctl start mysql

# 开机启动mysql
# systemctl enable mysql

# 查看mysql   状态
# systemctl status mysql

这里若没有配置mysql源则会安装mariadb ，故需先卸载yum remove mariadb -y

安装git

# yum install git -y

获取falcon源码

# git clone https://github.com/open-falcon/falcon-plus.git

初始化数据库

# cd /opt/src/falcon-plus-master/scripts/mysql/db_schema

[root@rhel-node01 db_schema]# mysql -h 127.0.0.1 -u root -p < 1_uic-db-schema.sql 
Enter password: 
[root@rhel-node01 db_schema]# mysql -h 127.0.0.1 -u root -p < 2_portal-db-schema.sql 
Enter password: 
[root@rhel-node01 db_schema]# mysql -h 127.0.0.1 -u root -p < 3_dashboard-db-schema.sql 
Enter password: 
[root@rhel-node01 db_schema]# mysql -h 127.0.0.1 -u root -p < 4_graph-db-schema.sql 
Enter password: 
[root@rhel-node01 db_schema]# mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql 
Enter password: 

# 验证
[root@rhel-node01 db_schema]# mysql -u root -p
Enter password:
