保姆级教程！甲骨文ARM DD成Debian10并升级内核成5.10 香喷喷的4核24G 100G。Debian10系统，内核版本5.10分享一下操作流程，希望能够对mjj们有所帮助～安装Debian 10参考：https://www.vvars.com/package-tool/Oracle-oracle-ARM-reinstall-Debian-10.html新建实例时选的 ubuntu 20.4，非 mini 版用到的脚本来自https://github.com/bohanyang/debiDownloadDownload the script with curl:curl -fLO https://raw.githubusercontent.com/bohanyang/debi/master/debi.shchmod a+rx debi.shsudo ./debi.sh --architecture arm64 --user root --password password设置默认root的密码为password，登陆成功之后记得自己输入passwd修改密码！！！没报错的话继续运行：sudo shutdown -r now更新内核至5.10 参考：https://p3terx.com/archives/debian-linux-vps-server-wireguard-installation-tutorial.html1、添加 back­ports 源echo "deb http://deb.debian.org/debian $(lsb_release -sc)-backports main" | sudo tee /etc/apt/sources.list.d/backports.listsudo apt updateuname -r此时看到的版本应该是4.19的，为了之后安装warp方便，我们可以更新内核到新版，5.6以上就自带了wireguard了，现在最新的是5.10sudo apt -t $(lsb_release -sc)-backports install linux-image-$(dpkg --print-architecture) linux-headers-$(dpkg --print-architecture) --install-recommends -y安装完重启，执行 uname -r 命令，现在已经是5.10了。PS：1、安装宝塔面板，nginx和php可以选择编译安装，我一键安装会报错；2、wget -O box.sh https://raw.githubusercontent.com/BlueSkyXN/SKY-BOX/main/armbox.sh && chmod +x box.sh && clear && ./box.shARM适配的一些脚本，来源https://t.me/blueskyxnblog3、Mac用户可以不用putty，用更简单的方法来登陆甲骨文，参考：https://docs.oracle.com/en-us/iaas/Content/Compute/Tasks/accessinginstance.htm

CentOS 7.5静默安装Oracle 11g 现在linux系统越来越被大家普及，但是linux一般没有桌面想要部署oralce难度很大，今天来给大家介绍一下linux环境部署oracle 11g1.安装前环境准备1.1.配置本地yum源#因公司内网环境，没有互联网，所以需要配置本地yum源，安装所需依赖包等。 #挂载ios镜像centos7.5-1804 [root@oracle ~]#mount /dev/cdrom /mnt #备份原配置文件 [root@oracle ~]#cd /etc/yum.repos.d/ [root@oracle ~]#mkdir bak [root@oracle ~]#mv * bak #创建yum配置文件 [root@oracle ~]#vi /etc/yum.repos.d/local.repo #添加以下内容 [local] name=local baseurl=file:///mnt gpgcheck=0 enabled=1 #清空yum所有源信息 [root@oracle ~]#yum clean all #查看本地源的所有软件 [root@oracle ~]#yum list1.2上传解压oracle 11g安装包#将下载的linux.x64_11gR2_database_1of2.zip和linux.x64_11gR2_database_2of2.zip解压到/usr/local/apps/oracle目录 [root@oracle ~]# mkdir -p /usr/local/apps/oracle [root@oracle ~]# cd /usr/local/apps/oracle [root@oracle oracle]# unzip p13390677_112040_Linux-x86-64_1of7.zip && unzip p13390677_112040_Linux-x86-64_2of7.zip #没有安装unzip命令工具的安装一下 [root@oracle ~]# yum install unzip –y #解压后会产生一个database目录，即/usr/local/apps/oracle/database，目录里面是oracle11g企业版的安装文件1.3.给本机服务IP地址作个映射#添加本机IP地址和主机名 [root@oracle oracle]# vim /etc/hosts 10.0.0.10 oracle 1.4.关闭selinux#修改SELINUX=disabled [root@oracle ~]#vi /etc/selinux/config SELINUX=disabled [root@oracle ~]#setenforce 0 setenforce: SELinux is disabled1.5.关闭防火墙[root@oracle ~]#service iptables stop [root@oracle ~]#systemctl stop firewalld [root@oracle ~]#systemctl disable firewalld 1.6.安装Oracle 11g依赖包 [root@oracle ~]#yum install gcc make ksh libaio libaio-devel numactl-devel sysstat unixODBC unixODBC-devel pcre-devel –y1.7.添加安装用户和用户组#创建用户组 [root@oracle ~]#groupadd oinstall [root@oracle ~]#groupadd dba #创建oracle用户并指定用户组 [root@oracle ~]#useradd -g oinstall -G dba oracle #为oracle用户设置密码 [root@oracle ~]#passwd oracle #查看用户信息 [root@oracle ~]#id oracle uid=1001(oracle) gid=1001(oinstall) 组=1001(oinstall),1002(dba) #如显示以上类似信息则表示添加用户和用户组成功 1.8.修改内核参数[root@oracle ~]#vi /etc/sysctl.conf #添加以下内容 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 1073741824 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 #其中shmmax是单个共享内存段的最大值，一般设置为本机物理内存的一半，单位为byte，可根据自己的实际情况做相应调整 #使新内核参数生效 [root@oracle ~]#sysctl –p1.9.修改用户的限制文件[root@oracle ~]#vi /etc/security/limits.conf #添加以下内容 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 102401.10.修改/etc/pam.d/login文件[root@oracle ~]#vi /etc/pam.d/login #添加以下内容 session required /lib64/security/pam_limits.so session required pam_limits.so 1.11.修改/etc/profile文件[root@oracle ~]#vi /etc/profile #添加以下内容 if [ $USER = "oracle" ];
