一、准备用户环境
1.1、计划将数据库安装在 /dev/sdb 磁盘上
mkdir /u01
echo "/dev/sdb /u01 ext4 defaults 0 0 " >> /etc/fstab
mount -a
df -h
1.2、添加用户、组及安装目录
groupadd -g 6000 oinstall
groupadd -g 6001 dba
groupadd -g 6002 oper
useradd -g oinstall -G dba,oper oracle
mkdir -p /u01/app/oracle
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle/product/11.2.0/db_1
chmod -R 775 /u01/app
mkdir /u01/app/oraInventory
chown oracle:oinstall /u01/app/oraInventory/
passwd oracle <<EOF
Admin@123Pass
Admin@123Pass
EOF
1.3、配置Oracle用户环境变量
echo "export PATH=/bin:/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
export ORACLE_BASE=/u01/app/oracle # Oracle Base
export ORACLE_HOME=\$ORACLE_BASE/product/11.2.0/db_1 # Oracle Home
export PATH=\$ORACLE_HOME/bin:\$PATH
export ORACLE_SID=orcl
export ORACLE_UNQNAME=orcl
export NLS_LANG=\"AMERICAN_AMERICA.UTF8\"
alias ss=\"rlwrap sqlplus / as sysdba\"
alias sqlplus=\"rlwrap sqlplus\"
alias rman=\"rlwrap rman\"
export HISTTIMEFORMAT=\"%d/%m/%y %T\"
" >> /home/oracle/.bash_profile
echo "export alfs=\"/u01/app/oracle/diag/rdbms/orcl/orcl/trace/alert_orcl1.log\"
" >> /root/.bash_profile
1.4、修改 /etc/security/limits.conf
echo "
#oracle SETTING
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536" >> /etc/security/limits.conf
1.5、修改 /etc/sysctl.conf
echo "
#oracle SETTING
kernel.shmall = 4294967296
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
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 = 1048586
net.ipv4.tcp_wmem = 262144 262144 262144
net.ipv4.tcp_rmem = 4194304 4194304 4194304 " >> /etc/sysctl.conf
sysctl -p
1.6、修改 /etc/pam.d/login
echo "
#oracle SETTING
session required pam_limits.so " >> /etc/pam.d/login
1.7、修改 /etc/profile
echo "
#oracle SETTING
if [ \$USER = \"oracle\" ]; then
if [ \$SHELL = \"/bin/ksh\" ]; then
ulimit -u 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi" >> /etc/profile
1.8、关闭transparent_hugepage的配置
echo " if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi" >> /etc/rc.local
chmod +x /etc/rc.d/rc.local
echo never > /sys/kernel/mm/transparent_hugepage/enabled
cat /sys/kernel/mm/transparent_hugepage/enabled
1.9、配置本地源：
echo "[local]
name=local
baseurl=file:///media
gpgcheck=0
enabled=1" > /etc/yum.repos.d/local.repo
1.10、安装依赖的软件包
yum clean all
yum list
yum grouplist
yum groupinstall 'Development tools' 'Compatibility libraries' 'Desktop Platform Development' -y
yum install libaio-devel unixODBC unixODBC-devel ksh elfutils-libelf-devel -y
yum install -y binutils compat-libstdc++-33 compat-libcap1 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat ksh unixODBC unixODBC-devel
rpm -q --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" binutils compat-libstdc++-33 compat-libcap1 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat ksh unixODBC unixODBC-devel
1.11、默认启动级别设置为图形界面
systemctl set-default multi-user.target
systemctl set-default graphical.target
1.12、网卡配置（使用nmcli配置）
nmcli con add con-name ens192 ifname ens192 autoconnect yes type ethernet ip4 192.168.10.25/24 gw4 192.168.10.250
nmcli con up ens192
二、开始安装
2.1、准备安装文件，开始安装（使用本地JDK，则不会出现中文乱码）
mv p13390677_112040_Linux-x86-64_* /u01/app/oracle/
chown oracle:oinstall /u01/app/oracle/ -R
su - oracle
cd /u01/app/oracle/
unzip p13390677_112040_Linux-x86-64_1of7.zip
unzip p13390677_112040_Linux-x86-64_2of7.zip
export DISPLAY=":0"
[root@emrdb soft]# java -version
openjdk version "1.8.0_222-ea"
OpenJDK Runtime Environment (build 1.8.0_222-ea-b03)
OpenJDK 64-Bit Server VM (build 25.222-b03, mixed mode)
cd /u01/app/oracle/database
./runInstaller -jreLoc /usr/lib/jvm/jre-1.8.0 &
2.2、缺少 pdksh-5.2.14，可选择忽略
解决办法：
vim /u01/app/oracle/database/stage/cvu/cvu_config
将 CV_ASSUME_DISTID=OEL4 改为： CV_ASSUME_DISTID=OEL7
或者运行以下命令安装：
./runInstaller -ignorePrereq -jreLoc /usr/lib/jvm/jre-1.8.0
2.3、安装Oracle 11g 86%报错：Error in invoking target 'agent nmhs' of makefile
编辑 ins_emagent.mk 后，重试即可。
在$(MK_EMAGENT_NMECTL) 后 添加 -lnnz11【注：-前有个空格，第一个是字母l，后面两个是数字1】
vim /u01/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk
vim $ORACLE_HOME/sysman/lib/ins_emagent.mk
$(MK_EMAGENT_NMECTL) -lnnz11
2.4、执行配置脚本，完成数据库软件安装
