ScyllaDB 使用 1.5 版本，以 admin 用户身份安装。
Scylla 只支持 CentOS 7.2 以上版本。
基础环境
操作系统： CentOS 7.2；
集群节点(虚拟机)：172.16.134.15 ~ 17；
基础准备
安装依赖和卸载 abrt ( abrt 和 coredump 配置冲突 )：
sudo yum install -y qt-settings epel-release wget
sudo yum remove -y abrt
准备工作目录：
mkdir -p ops/admin/20170316_build_scylladb
cd ops/admin/20170316_build_scylladb
准备机器列表文件list_all：
172.16.134.15
172.16.134.16
172.16.134.17
准备机器列表文件list_all_hostname：
v134015.dc1.domain.com
v134016.dc1.domain.com
v134017.dc1.domain.com
本地 REPO 制作
因为生产环境更多的是离线安装，所以我们需要制作本地 REPO。要使用--downloadonly，需要安装：
sudo yum install -y yum-plugin-downloadonly
选择一台可以连接互联网的机器，下载中国源：
sudo wget -O /etc/yum.repos.d/scylla.repo http://downloads.scylladb.cn/1.5/scylla.cn.repo
下载所有 RPM 包至 YUM 缓存：
sudo yum install -y scylla --downloadonly
得到下载的 RPM 列表rpm_list如下：

制作本地 REPO，脚本make_local_repo.sh内容如下，我们需要保证该包和 YUM 缓存具备一样的目录结构：
#!/bin/bashset -xOPS_BASE_PATH=/home/admin/ops/admin/20170316_build_scylladbSCYLLA_VERSION=1.5REPO_NAME=scylla_${SCYLLA_VERSION}_repoLOCAL_REPO_PATH=${OPS_BASE_PATH}/${REPO_NAME}releasever=`rpm -qi centos-release | grep "Version" | awk -F ':' '{print$2}' | sed 's/ //g'`basearch=`rpm -qi centos-release | grep "Architecture" | awk -F ':' '{print$2}' | sed 's/ //g'`yum_cache_path=/var/cache/yum/${basearch}/${releasever}cd ${yum_cache_path}tar zcvf ${OPS_BASE_PATH}/${REPO_NAME}.tar.gz ./*
这样，在/home/admin/ops/admin/20170316_build_scylladb下就生成了一个本地安装包scylla_1.5_repo.tar.gz。
安装
拷贝 REPO 至 172.16.134.15，分发：
#!/bin/bashset -xOPS_BASE_PATH=/home/admin/ops/admin/20170316_build_scylladbSCYLLA_VERSION=1.5REPO_NAME=scylla_${SCYLLA_VERSION}_reporeleasever=`rpm -qi centos-release | grep "Version" | awk -F ':' '{print$2}' | sed 's/ //g'`basearch=`rpm -qi centos-release | grep "Architecture" | awk -F ':' '{print$2}' | sed 's/ //g'`yum_cache_path=/var/cache/yum/${basearch}/${releasever}pscp -h list_all ${OPS_BASE_PATH}/${REPO_NAME}.tar.gz /tmppssh -h list_all "sudo tar zxvf /tmp/${REPO_NAME}.tar.gz -C ${yum_cache_path}"
修改scylla.repo：
[scylla]
name=Scylla for Centos $releasever - $basearch
baseurl=file:///var/cache/yum/$basearch/$releasever/
enabled=1
gpgcheck=0
[scylla-generic]
name=Scylla for centos $releasever
baseurl=file:///var/cache/yum/$basearch/$releasever/
enabled=1
gpgcheck=0
[scylla-3rdparty]
name=Scylla 3rdParty for Centos $releasever - $basearch
baseurl=file:///var/cache/yum/$basearch/$releasever/
enabled=1
gpgcheck=0
[scylla-3rdparty-generic]
name=Scylla 3rdParty for Centos $releasever
baseurl=file:///var/cache/yum/$basearch/$releasever/
enabled=1
gpgcheck=0
分发scylla.repo：
pscp -h list_all /etc/yum.repos.d/scylla.repo /tmp
pssh -h list_all "sudo cp /tmp/scylla.repo /etc/yum.repos.d/"
安装 scylla：
pssh -h list_all "sudo yum install -y scylla"
配置及启动
分发list_all到所有节点/tmp目录：
pscp -h list_all list_all /tmp
修改/etc/scylla/scylla.yaml，脚本init_scylla_config.sh内容如下：
#!/bin/bashprocessor_num=`cat /proc/cpuinfo | grep processor | wc -l`for ip in `cat /tmp/list_all`;do ip_list="${ip_list},${ip}";doneip_list=`echo ${ip_list} | sed 's/^[ \t,]*//g'`host_ip=`hostname -i`sudo cp /etc/scylla/scylla.yaml /etc/scylla/scylla.yaml.oringincp /etc/scylla/scylla.yaml /tmpsed -i "s/cluster_name: 'Test Cluster'/cluster_name: 'Dev Test Cluster'/" /tmp/scylla.yamlsed -i "s/seeds: \"127.0.0.1\"/seeds: \"${ip_list}\"/" /tmp/scylla.yamlsed -i "s/#memtable_flush_writers: 8/memtable_flush_writers: ${processor_num}/" /tmp/scylla.yamlsudo sed -i "s/listen_address: localhost/listen_address: ${host_ip}/" /tmp/scylla.yamlsudo sed -i "s/rpc_address: localhost/rpc_address: ${host_ip}/" /tmp/scylla.yamlsudo sed -i "s/api_address: 127.0.0.1/api_address: ${host_ip}/" /tmp/scylla.yaml sudo cp /tmp/scylla.yaml /etc/scylla/scylla.yaml
分发脚本并执行：
pscp -h list_all init_scylla_config.sh /tmp
pssh -h list_all "sudo /bin/bash /tmp/init_scylla_config.sh"
初始化，虚拟机请一路 YES (直到最后询问是否需要安装 node_exporter 的时候选择 NO)：
sudo scylla_setup
sudo reboot
重启后启动进程：
sudo systemctl start scylla-serversudo systemctl start scylla-jmx# 观察集群情况nodetool status
