pdksh-5.2.14-37.el5_8.1 (x86_64)

三、数据库安装

1. 编辑文件/etc/hosts添加主机名及IP地址

   [root@slave ~]# vim /etc/hosts
   193.192.168.4.185 slave.com
   2.创建用户和组
   [root@slave ~]# groupadd -g 500 oinstall
   [root@slave ~]# groupadd -g 501 dba
   [root@slave ~]# useradd -g oinstall -G dba -u 500 oracle
   [root@slave ~]# passwd oracle
   Changing password for user oracle.
   New password:
   Retype new password:
   passwd: all authentication tokens updated successfully.

2. 创建目录
   [root@slave ~]# mkdir -p /u01/app/oracle
   [root@slave ~]# mkdir -p /data/oradata
   [root@slave ~]# mkdir -p /backup/{expdbbackup,rmanbackup,onlinelog,archivelog,backupsh}
   [root@slave ~]# chown -R oracle:oinstall /u01
   [root@slave ~]# chown -R oracle:oinstall /data
   [root@slave ~]# chown -R oracle:oinstall /backup

3. 扩大tmpfs
   oracle 11g引入了memory_target参数，memory_target 和 /dev/shm（即tmpfs）有紧密联系，tmpfs的大小制约了memory_target的使用范围
   1) 查看tmpfs大小(tmpfs默认的大小是物理内存的一半)
   [root@slave ~]# df -h
   Filesystem Size Used Avail Use% Mounted on
   /dev/mapper/centos-root 50G 1.2G b6d 49G 3% /
   devtmpfs 5.8G 0 5.8G 0% /dev
   tmpfs 18G 0 18G 0% /dev/shm
   tmpfs 5.8G 8.7M 5.8G 1% /run
   tmpfs 5.8G 0 5.8G 0% /sys/fs/cgroup
   /dev/sda1 1014M 143M 872M 15% /boot
   tmpfs 1.2G 0 1.2G 0% /run/user/0
   /dev/mapper/centos-u01 20G 45M 19G 1% /u01
   /dev/mapper/centos-data 50G 53M 47G 1% /data
   /dev/mapper/centos-backup 50G 53M 47G 1% /backup

2) 编辑/etc/fstab
[root@slave ~]# vim /etc/fstab
tmpfs /dev/shm tmpfs defaults,size=18432M 0 0

3) 重新挂载
[root@slave ~]# mount -o remount /dev/shm

5.修改内核参数
1) 编辑/etc/sysctl.conf添加以下内容
[root@slave ~]# vim /etc/sysctl.conf
#oracle
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 8388608
kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=262144
net.core.wmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_max=1048576
#end
2) 执行sysctl -p命令使文件生效
[root@slave ~]# sysctl -p
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 8388608
kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576

1. 修改系统资源限制
   1) 编辑/etc/security/limits.conf添加以下内容
   [root@slave ~]# vim /etc/security/limits.conf
   #oracle
   oracle soft nproc 2047
   oracle hard nproc 16384
   oracle soft nofile 1024
   oracle hard nofile 65536
   #end
   2) 编辑文件/etc/pam.d/login添加以下内容
   [root@slave ~]# vim /etc/pam.d/login
   #Oracle
   session required pam_limits.so
   #end
   3) 编辑/etc/profile文件添加以下内容
   [root@slave ~]# vim /etc/profile
   #oracle
   if [ $USER = "oracle" ]; then
   if [ $SHELL = "/bin/ksh" ]; then
   ulimit -p 16384
   ulimit -n 65536
   else
   ulimit -u 16384 -n 65536
   fi
   umask 022
   fi
   #end
2. 设置环境变量
   1) 在oracle用户下编辑文件.bash_profile添加以下内容
   [root@slave ~]# su - oracle
   [oracle@slave ~]$ vim .bash_profile
   ORACLE_BASE=/u01/app/oracle
   ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
   ORACLE_SID=oa
   PATH=$ORACLE_HOME/bin:$PATH
   export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH

2) 执行source .bash_profile命令使环境变量生效
[oracle@slave ~]$ 5ac source .bash_profile

1. 关闭Linux安全增强
   1) 编辑/etc/selinux/config修改SELINUX=disabled

2）执行setenforce 0不重启操作系统临时关闭selinux模式
[oracle@slave ~]$ setenforce 0

9.安装oracle
1) 上传安装文件
[root@slave ~]# cd /home/oracle/
[root@slave oracle]# ls
p13390677_112040_Linux-x86-64_1of7.zip p13390677_112040_Linux-x86-64_2of7.zip

2) 解压
[root@slave oracle]# unzip p13390677_112040_Linux-x86-64_1of7.zip
[root@slave oracle]# unzip p13390677_112040_Linux-x86-64_2of7.zip
[root@slave oracle]# ls
database p13390677_112040_Linux-x86-64_1of7.zip p13390677_112040_Linux-x86-64_2of7.zip
3) 使用Xshell远程登录执行runInstaller开始安装
[root@slave ~]# export DISPLAY=192.168.4.56:0.0
[root@slave ~]# su - oracle
Last login: Fri Jan 18 19:24:18 CST 2019 on pts/1
[oracle@slave ~]$ export DISPLAY=192.168.4.56:0.0
4）测试结果
[root@slave ~]# xhost +
