下载阿里开源数据库

wget https://github.com/alibaba/AliSQL/archive/master.zip .
unzip master.zip
cd AliSQL-master
cmake -DCMAKE_BUILD_TYPE="Release" -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DWITH_EMBEDDED_SERVER=0 -DWITH_EXTRA_CHARSETS=all -DWITH_MYISAM_STORAGE_ENGINE=1  -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_CSV_STORAGE_ENGINE=1  -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 
make && make install

安装环境变量

export PATH=/usr/local/mysql/bin:$PATH

开启TokuDB，不执行会提示：[ERROR] TokuDB: Huge pages are enabled, disable them before continuing
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
   echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
   echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi

配置并启动

cd /usr/local/mysql
./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
cp ./support-files/my-default.cnf /etc/my.cnf
cp ./support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chown -R mysql:mysql /usr/local/mysql

vim /etc/profile
export PATH=/usr/local/mysql/bin:$PATH

source /etc/profile
修改启动文件里面的base和data
vim  /etc/init.d/mysqld 

basedir=/usr/local/mysql
datadir=/usr/local/mysql/data

启动mysql service mysqld start

开机启动

chkconfig --level 35 mysqld on

设置mysql密码

mysqladmin -u root password

安装redis

tar zxvf redis-3.2.8.tar.gz
cd redis-3.2.8
make
make PREFIX=/usr/local/redis install
mkdir /usr/local/redis/etc
mkdir /usr/local/redis/var
cp redis.conf /usr/local/redis/etc/

修改配置文件

daemonize yes
bind 192.168.20.88
port 6379
timeout 300
loglevel notice
logfile "/usr/local/redis/var/redis.log"
databases 16
dbfilename dump.rdb
dir "/usr/local/redis/var"
#requirepass 123456
maxclients 10000
maxmemory 1024MB

appendonly yes
appendfilename "appendonly.aof"
appendfsync everysec

启动redis

/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

编译二进制文件

因为我的golang是原安装默认位置在/usr/lib/golang/，所以要在这个目录下建立github.com/open-falcon/
cd /usr/lib/golang/src/github.com/open-falcon/
git clone https://github.com/open-falcon/falcon-plus.git
cd falcon-plus
make all
make pack

建立工作目录
export HOME=/home/work
export WORKSPACE=$HOME/open-falcon
mkdir -p $WORKSPACE
cd /home/work/open-falcon
tar -zxvf /usr/lib/golang/src/github.com/open-falcon/open-falcon-v0.2.0.tar.gz -C /home/work/open-falcon

查找要修改的数据库文件，修改password为你的数据库密码

grep -r root ./*/config/cfg.json

检查redis配置

导入数据库文件

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

启动falcon

./open-falcon start

检查

./open-falcon check

安装登录页

备注： dashboard 和open-falcon 同级目录

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 groupinstall "Development tools"

安装插件
cd $WORKSPACE/dashboard/
virtualenv ./env
./env/bin/pip install -r pip_requirements.txt

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

先用./env/bin/python wsgi.py 测试启动是否正确

如果报so文件找不到，是因为你自己安装的msyql没有关联系统目录下

ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18 （32位）
  ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/libmysqlclient.so.18 （64位）

生产方式启动
bash control start

访问

open http://IP:8081 in your browser.

注册

登陆

页面

-------------------------------------------

在其他机器安装agent

复制一份agent出来，修改里面的2处配置文件

vim agent/config/cfg.json

把图里0.0.0.0替换成open-falcon也就是server端的地址

然后打包此agent

tar zcvf agent.tar.gz agent

把这个修改完的agent可以放到任意你需要采集的机器上去，启动agengt（open-falcon是server的你可以复制一个过去）

./open-falcon start agent
