Centos 部署 open-falcon 0.3.x 单机部署(一)环境安装

参考链接:

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

https://www.cnblogs.com/straycats/p/10787916.html

1 环境配置

1.1 安装wget、vim

yum install -y wget vim

1.2 安装git

yum install -y git

安装结束后,确认是否满足官方要求的Git >= 1.7.5

git version

1.3 安装golang

# 通过fedora的epel仓库来安装golang

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

安装结束后,确认是否满足官方要求的Go >= 1.6

go version

或者参考https://www.cnblogs.com/reboot777/p/10985731.html

(1)下载golang安装包

wget https://dl.google.com/go/go1.12.5.linux-amd64.tar.gz

(2)解压至/usr/local文件夹

tar -C /usr/local -xzf go1.12.5.linux-amd64.tar.gz

(3)配置环境变量 

vim /etc/profile

export GOROOT=/usr/local/go
export GOBIN=$GOROOT/bin
export PATH=$PATH:$GOBIN

source /etc/profile使修改生效.

go env 测试

1.4 安装mariadb及启动

yum install mariadb-server mariadb
systemctl start mariadb  #启动MariaDB
systemctl stop mariadb  #停止MariaDB
systemctl restart mariadb  #重启MariaDB
systemctl enable mariadb  #设置开机启动
systemctl status mariadb.service # 查看状态

1.5 安装redis

# 通过fedora的epel仓库来安装redis

yum install -y epel-release
yum install -y redis

# 启动、开机启动redis

systemctl start redis
systemctl enable redis

1.6 设置临时变量,拉取后端(open-falcon)的源码

export GOROOT=/usr/lib/golang
export GOPATH=/data/worktable

# 创建存放源码文件的目录

mkdir -p $GOPATH/src/github.com/open-falcon

# 进入该目录

cd $GOPATH/src/github.com/open-falcon

# 拉取源码

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

1.7 初始化数据库

# 进入目录

cd $GOPATH/src/github.com/open-falcon/falcon-plus/scripts/mysql/db_schema

# 执行5个脚本初始化数据库

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

PS.在运行“mysql -h..................”时会提示“Enter password”,如果mysql的root没有设置密码,回车即可。

若要设置更改密码

更改mysql用户名密码

vi /etc/my.cnf

2 在[mysqld]后面任意一行添加“skip-grant-tables”用来跳过密码验证的过程
3  重启MariaDB

systemctl restart mariadb

4 mysql -u root -p
在sql里输入命令

use mysql;
update user set authentication_string=PASSWORD("") where User='root';
update user set plugin="YOUR_KEY_WORDS";
flush privileges;
quit;

4 将my.cnf修改回来
5 再次重启mysql,完毕

1.8 编译后端的源码并打包

# 进入目录

cd $GOPATH/src/github.com/open-falcon/falcon-plus

# 编译所有模块

make all

# 打包

make pack

如果报错运行.sh文件提示‘\r’ command not found

解决方法
1 vim 文件
2 输入 : set ff=unix 然后一直回车
3 保存

打包完成后,工作目录/src/github.com/open-falcon/falcon-plus/目录下多了刚才打的压缩包“open-falcon-v0.3.tar.gz”
