open-falcon环境准备

安装golang

下载安装包

wget https://studygolang.com/dl/golang/go1.12.7.linux-amd64.tar.gz

解压并加入环境变量

# tar -C /usr/local -zxvf go1.12.7.linux-amd64.tar.gz 
# vim /etc/profile
export PATH=$PATH:/usr/local/go/bin

# source /etc/profile

安装redis

下载源码包

wget http://download.redis.io/redis-stable.tar.gz

解压并编译

tar zxvf redis-stable.tar.gz 
cd redis-stable
make PREFIX=/usr/local/redis install

启动

mkdir /usr/local/redis/conf/6379 -p
cp redis.conf /usr/local/redis/conf/6379/

# /usr/local/redis/bin/redis-server /usr/local/redis/conf/6379/redis.conf 
10775:C 30 Jul 2019 21:32:13.338 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
10775:C 30 Jul 2019 21:32:13.338 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=10775, just started
10775:C 30 Jul 2019 21:32:13.338 # Configuration loaded

这里只是简单安装以下，就不加入systemd了

安装MySQL

使用yum快速安装，版本选择mysql5.7

下载rpm包：https://dev.mysql.com/downloads/repo/yum/

rpm -Uvh mysql80-community-release-el7-3.noarch.rpm

默认安装的是mysql5.8，即最新的，这里要选择MySQL5.7安装，首先关闭mysql5.8版本

yum-config-manager --disable mysql80-community

开启mysql5.7

yum-config-manager --enable mysql57-community

以上如果没有yum-config-manager这个命令，则下载即可

yum -y install yum-utils

执行完以上命令，repo仓库会自动发生变化

下载

yum -y install mysql-community-server

启动并加入开机自启

systemctl start mysqld.service
systemctl enable mysqld.service

查看临时密码

grep 'temporary password' /var/log/mysqld.log

修改密码

ALTER USER 'root'@'localhost' IDENTIFIED BY 'Devilf@2018';

安装可参考官方文档：https://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/

初始化数据库

导入表结构

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 -pDevilf@2018 &lt; 1_uic-db-schema.sql
mysql -h 127.0.0.1 -u root -pDevilf@2018 &lt; 2_portal-db-schema.sql
mysql -h 127.0.0.1 -u root -pDevilf@2018 &lt; 3_dashboard-db-schema.sql
mysql -h 127.0.0.1 -u root -pDevilf@2018 &lt; 4_graph-db-schema.sql
mysql -h 127.0.0.1 -u root -pDevilf@2018 &lt; 5_alarms-db-schema.sql
rm -rf /tmp/falcon-plus/

准备open-falcon二进制包

下载二进制包

wget https://github.com/open-falcon/falcon-plus/releases/download/v0.3/open-falcon-v0.3.tar.gz

下载完成后先不要着急解压。
