sysstat-10.1.5-1.el7.x86_64
2.2、Installation Fixup Scripts
如果安装过程出现错误，会用到这个功能去自动修复，但是修复完后还是需要手动去确认确实满足了。
参考：https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#LADBI1146
During installation, for certain prerequisite verification failures, click Fix & Check Again to generate a fixup script (runfixup.sh). You can run this script as the root user to complete the required preinstallation steps.
The fixup script:
Checks for and sets kernel parameters to values required for successful installation, including:
Shared memory parameters
Open file descriptor and UDP send/receive parameters
Oracle recommends that you do not modify the contents of the generated fixup script.
Note:
Using fixup scripts does not ensure that all the prerequisites for installing Oracle Database are met. You must still verify that all the preinstallation requirements are met to ensure a successful installation.
2.3、端口范围-Verifying UDP and TCP Kernel Parameters
编辑/etc/sysctl.conf
vi /etc/sysctl.conf
修改这行为： net.ipv4.ip_local_port_range = 9000 65500
如没有这行就添加一行
net.ipv4.ip_local_port_range = 9000 65500
使得修改生效
sysctl -p /etc/sysctl.conf
端口最小值大于9000 是为了防止熟知端口被使用到
最大值尽量大
检查当前端口范围
cat /proc/sys/net/ipv4/ip_local_port_range
参考：https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#LADBI1149
2.4、Installing the cvuqdisk Package for Linux
cluster安装才会使用到，单数据库安装忽略。
这个包在 Oracle Grid Infrastructure安装后的目录oracle_home1/cv/rpm中。
参考：https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#LADBI1151
2.5、配置/etc/hosts文件
确保/etc/hosts 文件中含有这一行
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
使用如下命令查看是否含有
grep 127.0.0.1 /etc/hosts
没有的话就编辑/etc/hosts文件加入这一行
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
参考：https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#LADBI1152
2.6、Disabling Transparent HugePages
To check if Transparent HugePages are enabled run one of the following commands as the root user:
cat /sys/kernel/mm/redhat_transparent_hugepage/enabled
或者
cat /sys/kernel/mm/transparent_hugepage/enabled
博主系统是rhel 8.7 不支持设置为never 就不设置了
参考：https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#LADBI1519
2.7、创建用户和组
groupadd --system oinstall
groupadd --system dba
adduser -m --system -g oinstall -G dba --shell /bin/bash oracle
参考：https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#LADBI1161
2.8、创建安装目录
mkdir -p /opt/oracle/product/11.2.0.1.0/dbhome
mkdir -p /opt/oraInventory
chown -R oracle:dba /opt/oracle/
chown -R oracle:dba /opt/oraInventory
2.9、Checking Resource Limits for the Oracle Software Installation Users
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 10240
oracle hard stack 32768
重启系统让配置生效
2.10、Configuring Kernel Parameters for Linux
vi /etc/sysctl.conf
插入如下内容
# ============================
# Oracle 11g
# ============================
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
kernel.shmall = 2097152
kernel.shmmni = 4096
# Replace kernel.shmmax with the half of your memory size in bytes
# if lower than 4 GB minus 1
# 6442450944 is 6 GigaBytes (12 GB of RAM / 2)
kernel.shmmax=6442450944
#
# Max number of network connections. Use sysctl -a | grep ip_local_port_range to check.
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
#
# The maximum allowed value, set to avoid overhead and input/output errors
fs.aio-max-nr = 1048576
# 512 * Processes
fs.file-max = 6815744
fs.suid_dumpable = 1
#
# To allow dba to allocate hugetlbfs pages
# 973 is your oinstall group, you can check this id with the grep oinstall /etc/group command
vm.hugetlb_shm_group = 973
2.11、Setting the shell profile
编辑 /etc/profile
vi /etc/profile
添加以下
if [ $USER = “oracle” ]; then
if [ $SHELL = “/bin/ksh” ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
使生效
source /etc/profile
2.12、 Configuring Oracle Software Owner Environment
指的是oracle用户
su - oracle
vim ~/.bashrc
插入以下内容
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
# Enter your hostname
ORACLE_HOSTNAME=debian; export ORACLE_HOSTNAME
ORACLE_UNQNAME=ORADB11G; export ORACLE_UNQNAME
ORACLE_BASE=/opt/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.1.0/dbhome_1; export ORACLE_HOME
ORACLE_SID=ORADB11G; export ORACLE_SID
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/lib64; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
umask 022
使生效
source ~/.bashrc
3、安装
3.1、直接使用oracle用户进行ssh登录
shsell中把ssh连接属性配置成 enable X11Forwarding
vi /etc/ssh/sshd_config
确定有下面这行
3.2、执行安装程序
3.2.1、runInstaller
cd /path/to/oracle/database/
./runInstaller
3.2.2、先决条件检查报错
pkksh可以忽略
参考：https://unix.stackexchange.com/questions/29554/pdksh-missing-from-rhel-6-and-centos-6
https://oracle-base.com/articles/11g/oracle-db-11gr2-installation-on-oracle-linux-6
安装compat-libstdc+±33-3.2.3
wget http://mirror.centos.org/centos/7/os/x86_64/Packages/compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm
yum localinstall -y compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm
rpm -qa | grep compat-libstdc++-33
参考：https://www.ibm.com/support/pages/ibm-watson-explorer-how-install-red-hat-enterprise-linux%C2%AE-8
再次检查
3.2.3、开始安装
3.2.4、等待安装完成
3.2.4、报错 INFO: //usr/lib64/libaio.so.1: undefined reference to `__stack_chk_fail@GLIBC_2.4’
这是因为libaio版本过高，对于oracle11g 的安装， libaio1库版本不能大于0.3.109 。
报错
f
点SKIP
/opt/oraInventory/orainstRoot.sh
/opt/oracle/product/11.2.0.4/dbhome_1/root.sh
安装成功
