1.Creating the Oracle Inventory Group
sudo groupadd oinstall
sudo groupadd dba
sudo groupadd oper
sudo useradd -g oinstall -G dba -d /opt/oracle -s /bin/bash oracle
sudo passwd oracle

2.Updating kernel parameters

sudo gedit /etc/sysctl.conf

#
# Oracle 11g
#
kernel.sem = 250 32000 100 128
kernel.shmall = 2097152
kernel.shmmni = 4096
# Replace kernel.shmmax with the half of your memory in bytes
# if lower than 4Go minus 1
# 1073741824 is 1 GigaBytes
kernel.shmmax=1073741824

# Try sysctl -a | grep ip_local_port_range to get real values
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

# Max value allowed, should be set to avoid IO errors
fs.aio-max-nr = 1048576
# 512 * PROCESSES / what really means processes ?
fs.file-max = 6815744

# To allow dba to allocate hugetlbfs pages
# 1001 is your oinstall group, id. grep oinstall /etc/group will give this value
vm.hugetlb_shm_group = 1001

sudo sysctl -p

sudo gedit /etc/security/limits.conf

# Oracle
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240

Check that /etc/pam.d/login contains a line like this one:
session required pam_limits.so

Now, update /etc/profile:
sudo gedit /etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi

4.Preventing from installation errors
To prevent from error genclntsh: Failed to link libclntsh.so.11.1 in make file for rdbms/lib/ins_rdbms.mk
beacause of missing library: /usr/bin/ld: cannot find /usr/lib64/libpthread_nonshared.a inside
we need to create a symlink for /usr/lib64:

sudo ln -s /usr/lib/x86_64-linux-gnu /usr/lib64

To help preventing from error lib//libagtsh.so: undefined reference to `nnfyboot' in make: rdbms/lib/dg4odbc] Error 1

sudo ln -sf /bin/bash /bin/sh
sudo ln -s /usr/bin/awk /bin/awk
sudo ln -s /usr/bin/rpm /bin/rpm
sudo ln -s /usr/bin/basename /bin/basename

To prevent from # /lib64/libgcc_s.so.1: File or directory does not exists, while creating lib/liborasdkbase.so.11.1 in ins_rdbms.mk, execute the command:
cd /lib64
sudo ln -s /lib/x86_64-linux-gnu/libgcc_s.so.1

Others configurations

Connect as Oracle user and set some default startup file
sudo su - oracle
touch .bashrc
ln -s .bashrc .bash_profile

vi .bashrc
umask 022
source .bashrc

export ORACLE_BASE=/opt/oracle/Oracle11g/
export ORACLE_SID=ZEN
export ORACLE_HOME=$ORACLE_BASE/product/db_1
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
export PATH=$PATH:$ORACLE_HOME/bin

Execute the .bashrc file or restart a bash shell

source .bashrc

Go in the extracted database folder and run the following commands:

export DISPLAY=:0
./runInstaller

To solve error # libnnz11.so: could not read symbols: Invalid operation /sysman/lib/ins_emagent.mk, enter the command:
export ORACLE_HOME=/opt/oracle/Oracle11gee/product/11.2.0/dbhome_1
sed -i 's/^\(\s*\$(MK_EMAGENT_NMECTL)\)\s*$/\1 -lnnz11/g' $ORACLE_HOME/sysman/lib/ins_emagent.mk

To solve error # nsglsn.c:(.text+0xc29): undefined reference to `ons_subscriber_close' /network/lib/ins_net_server.mk, enter the command:
sed -i 's/^\(TNSLSNR_LINKLINE.*\$(TNSLSNR_OFILES)\) \(\$(LINKTTLIBS)\)/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/network/lib/env_network.mk

To solve error # libocrutl11.so: undefined reference to `lfifcp' rdbms/lib/ins_rdbms.mk, enter the commands:
sed -i 's/^\(ORACLE_LINKLINE.*\$(ORACLE_LINKER)\) \(\$(PL_FLAGS)\)/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/rdbms/lib/env_rdbms.mk

libstdc++ 的版本不对应的话会报：
Error in invoking target 'all_no_orcl' of makefile '/home/oracle/10.2.0/db_1/rdbms/lib/ins_rdbms.mk'

sudo ln -s

sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.5 /usr/lib/libstdc++.so.5
sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.5.0.7 /usr/lib/libstdc++.so.5.0.7
sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/lib/libstdc++.so.6
sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.16 /usr/lib/libstdc++.so.6.0.16

但这样还是报错，直接忽略，安装通过。
