部署Open-falcon
==================草稿==后续会排版更新====
虚拟化平台 vmware@Workstation 10.0.1 build-1379776
系统版本 CentOS-7-x86_64-DVD-1908.iso
网络方式 NET
1 在虚拟化平台安装 CentOS 7,通过nmtui来查看网卡信息，使用ip addr 查看网卡地址，
#关闭selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
setenforce 0
#关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service
#重启服务器
Reboot
# 检查网卡信息
Nmtui
#修改网卡onboot=yes
cd /etc/sysconfig/network-scripts/
2 搭建阿里云yum源，这里要注意 curl –O http://mirrors.aliyun.com/repo/Centos-7.repo ，要在目录下 yum.repos.d 下执行。
具体命令如下：
[root@Open-falcon ~]# hostname Open-falcon
[root@Open-falcon ~]# cd /etc/yum.repos.d/
[root@Open-falcon yum.repos.d]# mkdir bak && mv * ./bak
[root@Open-falcon yum.repos.d]# curl –O http://mirrors.aliyun.com/repo/Centos-7.repo
[root@Open-falcon yum.repos.d]# yum clean all
[root@Open-falcon yum.repos.d]# yum makecache
[root@Open-falcon yum.repos.d]# yum -y update //更新所有包
3 安装GO语言环境
/var/run/yum.pid已被锁定，PID 为 XXXXX 的另一个程序正在运行
https://www.cnblogs.com/Lam7/p/5848267.html
解决方法：
直接在终端运行 rm –f /var/run/yum.pid 将该文件删除，然后再次运行yum
[root@Open-falcon ~]# yum -y install epel-release //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
[root@Open-falcon ~]# yum -y install go
且确认 版本大于 1.6版本
[root@Open-falcon ~]# go version
go version go1.8.3 linux/amd64
4 安装Redis
由于部署go时已经安装了epel，故直接执行下面的安装命令。
yum -y install redis
systemctl start redis
systemctl enable redis //开机启动
[root@localhost ~]# systemctl enable redis
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.
systemctl status redis //查看状态
5 安装wget , vim
yum install -y wget vim
6 安装MySQL
# 获取repo源
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
# 安装该rpm包
rpm -ivh mysql-community-release-el7-5.noarch.rpm
包名：mysql-5.6.40-linux-glibc2.12-x86_64.tar.gz（331MB）
find / -name “mysql*” –print //查找系统上的mysql文件
wget https://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.45-linux-glibc2.12-x86_64.tar.gz //上一个版本找不到 代用
https://cdn.mysql.com//archives/mysql-5.6/mysql-5.6.40-linux-glibc2.12-x86_64.tar.gz
FATAL ERROR: please install the following Perl modules before executing ./scripts/mysql_install_db:
Data::Dumper
解决方法 ：安装autoconf库 命令：yum -y install autoconf
[root@Open-falcon ~]# cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
[root@Open-falcon ~]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@Open-falcon ~]# chmod +x /etc/init.d/mysqld
[root@Open-falcon ~]# /etc/init.d/mysqld start
[root@localhost ~]# netstat
-bash: netstat: 未找到命令
解决办法：yum -y install net-tools
netstat -antup | grep :::3306
7. 初始化Mysql数据库
[root@Open-falcon ~]# mkdir falcon-plus
[root@Open-falcon ~]# cd falcon-plus
unzip falcon-plus-master.zip
-bash: unzip: 未找到命令
解决办法 yum install -y unzip zip
# 拉取源码
git clone https://github.com/open-falcon/falcon-plus.git
yum groupinstall "Development tools" –y 报错
解决办法 ：yum clean all
在运行命令

如果遇到这个问题 首先确认是否是多开了访问页面；其次是查看fe模块默认端口是1234，是否是8080
url:/api/v1/user/login (caused by: [errno 111] connection refused)
首先使用该命令检查是否有服务未启动
[root@open-falcon work]# ./open-falcon check
falcon-graph UP 6682
falcon-hbs UP 6701
falcon-judge UP 6715
falcon-transfer UP 6728

falcon-aggregator UP 6751
falcon-agent UP 6764
falcon-gateway UP 6779
falcon-api UP 6790
falcon-alarm UP 6808
./open-falcon restart
全部启动服务查看 访问页面是否可以启动
