## 说明：ARM架构的操作系统需要修改脚本的URL地址和YUM源地址。
## 第1步操作修改内容：
## export openGauss_Download_url=https://opengauss.obs.cn-south-1.myhuaweicloud.com/2.0.0/arm/openGauss-2.0.0-openEuler-64bit-all.tar.gz
## 第8步操作修改内容：
## wget -O /etc/yum.repos.d/openEulerOS.repo https://repo.huaweicloud.com/repository/conf/openeuler_aarch64.repo
############################################################

## 0.关闭virbr0网卡 [本地虚拟机软件标准化安装openEuler系统会默认存在virbr0网卡，删除该网卡以避免干扰数据库的安装]
## virsh net-destroy default
## virsh net-list
## echo "Net device virbr0 is disabled."

## 1.定义主机信息[请根据实际情况修改]
export MY_HOSTNAME=node1 ## 主机名
export MY_HOSTIP=192.168.8.133 ## IP地址
export MY_SOFTWARE_DIRECTORY=/soft/openGauss ## 软件包所在目录
export MY_XML=/soft/openGauss/clusterconfig.xml ## 集群配置文件XML
export openGauss_Download_url=https://opengauss.obs.cn-south-1.myhuaweicloud.com/2.0.0/x86_openEuler/openGauss-2.0.0-openEuler-64bit-all.tar.gz ## openGauss软件包下载地址

## 1. 设置主机名并配置hosts文件
hostnamectl set-hostname $MY_HOSTNAME
sed -i '/$MY_HOSTIP/d' /etc/hosts
echo "$MY_HOSTIP $MY_HOSTNAME #Gauss OM IP Hosts Mapping" >> /etc/hosts
cat /etc/hosts
echo "1.Configure /etc/hosts completed."
echo -e "\n"

## 2. 关闭防火墙
systemctl disable firewalld.service
systemctl stop firewalld.service
echo "Firewalld " `systemctl status firewalld|grep Active`
echo "2.Disable firewalld service completed."
echo -e "\n"

## 3. 关闭SELinux
sed -i '/^SELINUX=/d' /etc/selinux/config
echo "SELINUX=disabled" >> /etc/selinux/config
cat /etc/selinux/config|grep "SELINUX=disabled"
echo "3.Disable SELINUX completed."
echo -e "\n"

## 4. 设置操作系统字符集编码
echo "LANG=en_US.UTF-8" >> /etc/profile
source /etc/profile
echo $LANG
echo "4.Configure encoding completed."
echo -e "\n"

## 5. 设置操作系统时区
rm -fr /etc/localtime
ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
date -R
hwclock
echo "5.Configure Timezone completed."
echo -e "\n"

## 6. 关闭SWAP分区 [对于2G内存的设备，建议待安装完毕后再打开SWAP以间接 “扩容内存容量”]
sed -i '/swap/s/^/#/' /etc/fstab
swapoff -a
free -m
echo "6.Close swap partition completed."
echo -e "\n"

## 7. 配置SSH服务，关闭Banner，允许root远程登录
sed -i '/Banner/s/^/#/' /etc/ssh/sshd_config
sed -i '/PermitRootLogin/s/^/#/' /etc/ssh/sshd_config
echo -e "\n" >> /etc/ssh/sshd_config
echo "Banner none " >> /etc/ssh/sshd_config
echo "PermitRootLogin yes" >> /etc/ssh/sshd_config
cat /etc/ssh/sshd_config |grep -v ^#|grep -E 'PermitRoot|Banner'
echo "7.Configure SSH Service completed."
echo -e "\n"

## 8. 配置YUM源、安装依赖包、修改默认Python3版本
mkdir /etc/yum.repos.d/bak
mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak/
wget -O /etc/yum.repos.d/openEulerOS.repo https://repo.huaweicloud.com/repository/conf/openeuler_x86_64.repo
yum clean all
yum install -y bzip2 python3
yum install -y libaio-devel libnsl flex bison ncurses-devel glibc-devel patch readline-devel net-tools tar
mv /usr/bin/python /usr/bin/python2_bak
ln -s /usr/bin/python3 /usr/bin/python
python -V
echo "8.Configure Install Packages and change default Python version completed."
echo -e "\n"

## 9. 配置 sysctl.conf 和 performance.sh
cat >> /etc/sysctl.conf > /etc/security/limits.conf
echo "* hard stack 3072" >> /etc/security/limits.conf
echo "* soft nofile 1000000" >> /etc/security/limits.conf
echo "* hard nofile 1000000" >> /etc/security/limits.conf
echo "* soft nproc unlimited" >> /etc/security/limits.d/90-nproc.conf
tail -n 4 /etc/security/limits.conf
tail -n 1 /etc/security/limits.d/90-nproc.conf
echo "10.Configure resource limits completed."
echo -e "\n"

## 11. 关闭透明大页[Only for CentOS]
cat >>/etc/rc.d/rc.local /sys/kernel/mm/transparent_hugepage/defrag
fi
EOF
chmod +x /etc/rc.d/rc.local
/usr/bin/sh /etc/rc.d/rc.local
cat /sys/kernel/mm/transparent_hugepage/enabled
cat /sys/kernel/mm/transparent_hugepage/defrag
echo "11.Close transparent_hugepage completed."
echo -e "\n"

## 12. 禁用RemoveIPC[Only for openEuler]
sed -i '/^RemoveIPC/d' /etc/systemd/logind.conf
sed -i '/^RemoveIPC/d' /usr/lib/systemd/system/systemd-logind.service
echo "RemoveIPC=no" >> /etc/systemd/logind.conf
echo "RemoveIPC=no" >> /usr/lib/systemd/system/systemd-logind.service
systemctl daemon-reload
systemctl restart systemd-logind
loginctl show-session | grep RemoveIPC
systemctl show systemd-logind | grep RemoveIPC
echo "12.Disable RemoveIPC completed."
echo -e "\n"

## 13. 下载openGauss软件包
mkdir -p $MY_SOFTWARE_DIRECTORY
cd $MY_SOFTWARE_DIRECTORY
wget $openGauss_Download_url
echo "13.openGauss software download completed."
echo -e "\n"

## 14. 配置XML文件
rm -fr $MY_XML
cat >> $MY_XML
