linux下oracle11g的安装

准备工作：

系统：centos7.5.1804        yum仓库            有外网

step1：关闭防火墙，selinux

systemctl stop firewalld

vim /etc/selinux/config

       =====disabled

step2：创建oracle用户

groupadd dba                       //创建dba组

groupadd oinstall                  //创建oinstall组

useradd -g oinstall -G dba oracle             //创建oracle用户，并指定用户oracle的基本组和附加组

echo oracle |passwd --stdin oracle        //设置oracle用户的密码

step3：创建目录

mkdir -p  /home/oracle/oraInventory

mkdir -p /home/oracle/product/11.2.0/dbhome_1

step4:修改权限

chown -Rf oracle:oinstall  /home/oracle

chmod  -Rf  775   /home/oracle

step5：更改配置

vim /home/oracle/.bash_profile               ======》source  /home/oracle/.bash_profile

export ORACLE_BASE=/home/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export ORACLE_SID=orcl
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib

vim /etc/sysctl.conf              ====>stsctl -p 刷新配置

fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586

vim /etc/security/limits.conf

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

oracle soft stack 10240 

find / -name  pam_limits.so                  //以root去查找文件绝对路径

vim /etc/pam.d/login

session required /usr/lib64/security/pam_limits.so

session required pam_limits.so

vim /etc/profile

unset i
unset -f pathmunge

if [ $USER = "oracle" ]; then
      if [ $SHELL = "/bin/ksh" ]; then
           ulimit -p 16384
           ulimit -n 65536
     else
           ulimit -u 16384 -n 65536
     fi
fi

step6:rz上传Oracle11g的安装包到/home/oracle

安装依赖包：

 yum -y gcc make install libaio glibc compat-libstdc* elfutils-libelf-devel\*  gcc-c++  libaio-devel unixODBC\*  readline\*   xorg-x11-xauth

上传xorg-x11-server-utils-7.7-20.el7.x86_64.rpm，pdksh-5.2.14-30.x86_64.rpm,compat-libstdc++-33-3.2.3-72.el7.x86_6 4.rpm

yum -y install compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm 

rpm -ivh --force pdksh-5.2.14-30.x86_64.rpm

yum -y install xorg-x11-server-utils-7.7-20.el7.x86_64.rpm

tar -xf oracle11g安装包

客户机安装xmanage
