1、服务器要求
2、软件要求
下载
auto_hotdbinstall_HotDB2.5.*.tar.gz的HotDB Server安装包，如auto_hotdbinstall_HotDB2.5.3_v1.0_20191231.tar.gz。
部署步骤
本章命令，复制每个框的命令到shell执行即可
- 环境检查：所有服务器执行
-关闭selinux、firewalld等安全服务
#关闭selinux
setenforce 0;sed -i’s/SELINUX=enforcing/SELINUX=disabled/’ /etc/selinux/config;getenforce
#关闭防火墙
if [ -n “which systemctl2>/dev/null” ] ;then
systemctl list-unit-files --all | egrep ‘iptables|ip6tables|firewalld’| awk ‘{print $1}’ | xargs -I{} systemctl stop {}
systemctl list-unit-files --all | egrep ‘iptables|ip6tables|firewalld’| awk ‘{print $1}’ | xargs -I{} systemctl disable {}
else
serviceiptables stop 2>/dev/null
chkconfig iptables off 2>/dev/null
serviceip6tables stop 2>/dev/null
chkconfig ip6tables off 2>/dev/null
servicefirewalld stop 2>/dev/null
chkconfig firewalld off 2>/dev/null
fi
- 检查ssh等网络环境,保证ssh服务拥有较快的速度：推荐如下配置
#配置主机名和IP的映射关系
{
owf="/etc/hosts"
localip=ip a|grep 'inet '|grep -v '127.0.0'|grep-v 'secondary'|head -1|awk '{print $2}' | cut -d'/' -f 1#&& echo localiphostname"
ls “{owf}" &>/dev/null&& ! grep "{myflag}” “{owf}" &>/dev/null&& mv -f "{owf}” “{owf}".bak_`date+%Y_%m_%d_%H_%M_%S` cat > "{owf}” << EOF
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
${myflag}
EOF
}
#配置sshd，禁用DNS反向解析等功能
sed -i ‘s/[1]#[[:space:]]UseDNS yes./UseDNSno/g’ /etc/ssh/sshd_config
sed -i’s/[2]#[[:space:]]GSSAPIAuthentication yes/GSSAPIAuthenticationno/g’ /etc/ssh/sshd_config
sed -i’s/[3]#*[[:space:]]PermitRootLogin./PermitRootLogin yes/g’/etc/ssh/sshd_config
service sshd restart
关闭所有设定的时间同步服务
#关闭chronyd服务和ntpd服务，因为HotDB部署时会重建时间同步服务，避免冲突
timedatectl set-ntp no 2>/dev/null
service chronyd stop 2>/dev/null &&systemctl disable chronyd 2>/dev/null
service ntpd stop 2>/dev/null注释配置的java环境变量
#以下命令有输出，请自行注释配置的java变量，因为HotDB会自行设定，避免冲突
echo $JAVA_HOME
grep -Hi java ~/.bash_profile ~/.bashrc /etc/bashrc /etc/profile.d/* /etc/profileyum预安装：所有服务器执行
#脚本会自行安装，但推荐自行预安装，保证脚本运行过程中不会因为yum不全等问题而安装失败
#安装yum，命令无输出即可

部署命令
#cd切换到当前auto_hotdbinstall_HotDB2.5..tar.gz包所在位置，解压并复制包于标准安装目录/usr/local/hotdb下
mkdir -p /usr/local/hotdb
tar -zxvf auto_hotdbinstall_HotDB2..tar.gz-C /usr/local/hotdb
\cp auto_hotdbinstall_HotDB2.*.tar.gz /usr/local/hotdb
#一键安装，复制下述命令执行,看到success即可，过程中有些warning可忽略
–ntpdate-server-host=192.168.0.60参数建议使用接下来即将要部署的主计算节点所在IP，我这里是192.168.0.60

&& echo “installed successfully”
#若想查看安装进度，打开另一个窗口，执行下面命令即可
tail -fn 1000 /usr/local/hotdb/Install_Package/hotdbinstall.log
安装成功后，启动管理平台
bash/usr/local/hotdb/hotdb-management/bin/hotdb_management restart安装失败如何清理？成功请忽略
#若安装失败，执行下述命令清空原安装后，重新执行上面的安装命令即可

登陆HotDB管理平台
在浏览器的url输入框中填写安装管控平台的服务器IP:3324，输入默认的用户admin、密码admin，点击用户登陆，进入管理员界面进入集群部署界面
依次点击“集群管理”》》“计算节点集群”》》“集群部署”进入参数配置页面
选则“主备节点”，点击“参数配置”，进入参数配置界面，弹出环境建议提示框，关闭即可。
