centos7.4如何测试安装oracle成功
#将下面文字保存io.sh脚本文件，选择unix编码格式保存。脚本和oracle压缩包传入linux， linux进入io.sh 所在目录。
##chmod x io.sh 赋予执行权限， ./io.sh 运行脚本。更多内容看视频。
linux-centos7.5,xshell脚本安装oracle11g全程
setenforce 0 #临时关闭selinux
systemctl stop firewalld.service #关闭firewalld
yum -y install iptables-services #安装iptables
systemctl restart iptables.service
systemctl enable iptables.service
#安装依赖
yum -y install binutils compat compat-libstdc gcc gcc-c glibc glibc-devel ksh libaio libaio-devel libgcc libstdc libstdc -devel libXi libXtst make sysstat unixODBC unixODBC-devel unzip net-tools telnet
#chmod x
#、创建用户
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba -m oracle
#passwd oracle
#、创建安装目录，解压文件
mkdir -p /ora/oracle
chown -R oracle:oinstall /ora
chmod 755 -R /ora
