一.准备工作
1. centos7服务器一台（自备）
2. oracle安装包
官方下载地址：http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
根据自己服务器的情况选择对应的安装包下载，以我的为例，是64位操作系统的。下载完成后，有两个压缩文件linux.x64_11gR2_database_1of2.zip 和 linux.x64_11gR2_database_2of2.zip。
3.安装位置的选择
oracle尽量安装在剩余空间充足的位置，因此首先要查看服务器硬盘情况，如下：
[root@bogon ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/centos-root 50G 8.5G 42G 17% /
devtmpfs 16G 0 16G 0% /dev
tmpfs 16G 0 16G 0% /dev/shm
tmpfs 16G 9.0M 16G 1% /run
tmpfs 16G 0 16G 0% /sys/fs/cgroup
/dev/sda1 1014M 180M 835M 18% /boot
/dev/mapper/centos-home 142G 37M 142G 1% /home
tmpfs 3.2G 40K 3.2G 1% /run/user/0
/dev/sdb1 493G 825M 467G 1% /data
对比后发现/data余量最大，因此决定将oracle安装在/data目录
4.上传安装包
把下载下来的两个安装包通过xftp上传到/data目录（开始上传后继续执行后边的目录即可，无需等待上传完成）。
5.安装依赖包
安装依赖包之前，建议将yum源修改为aliyun源，下载速度快些：
[root@iz8vb8edqeyilgy4r9zci6z ~]# cd /etc
[root@iz8vb8edqeyilgy4r9zci6z etc]# mv yum.repos.d yum.repos.d.bak

修改成功后，安装如下依赖包：
yum -y install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel expat gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers libaio libaio-devel libgcc libstdc++ libstdc++-devel make pdksh sysstat unixODBC unixODBC-devel
安装完成后界面如下：
使用如下命令检查依赖是否安装完整：
rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel expat gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers libaio libaio-devel libgcc libstdc++ libstdc++-devel make pdksh sysstat unixODBC unixODBC-devel | grep "not installed"
发现pdksh没有安装，如下图：
通过wget命令直接下载pdksh的rpm包，我下载到了/tmp/，然后安装
[root@bogon ~]# wget -O /tmp/pdksh-5.2.14-37.el5_8.1.x86_64.rpm http://vault.centos.org/5.11/os/x86_64/CentOS/pdksh-5.2.14-37.el5_8.1.x86_64.rpm

发现所有依赖都已经安装完毕，至此依赖包安装完成
6.添加oracle用户组和用户
设置密码时pssswd oracle后直接输密码回车即可。
[root@bogon tmp]# groupadd oinstall
[root@bogon tmp]# groupadd dba
[root@bogon tmp]# useradd -g oinstall -G dba oracle -d /home/oracle
[root@bogon tmp]# passwd oracle
Changing password for user oracle.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@bogon tmp]# id oracle
uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba) ### 7.**配置hostname**
[root@bogon tmp]# vim /etc/hosts
# 编辑状态添加如下内容
服务器内网IP oracle
[root@bogon tmp]# ping -c 2 oracle
PING oracle (服务器内网IP) 56(84) bytes of data.
64 bytes from oracle (服务器内网IP): icmp_seq=1 ttl=64 time=0.049 ms
64 bytes from oracle (服务器内网IP): icmp_seq=2 ttl=64 time=0.032 ms
--- oracle ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 999ms
rtt min/avg/max/mdev = 0.032/0.040/0.049/0.010 ms ### 8.**优化OS内核参数**
kernel.shmmax 参数设置为物理内存的一半
[root@bogon tmp]# vim /etc/sysctl.conf
# 编辑状态输入如下内容/或修改对应的值
fs.aio-max-nr=1048576
fs.file-max=6815744
kernel.shmall=2097152
kernel.shmmni=4096
kernel.shmmax = 8589934592
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
[root@bogon tmp]# sysctl -p
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmni = 4096
kernel.shmmax = 8589934592
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 ### 9.**创建oracle安装目录**
[root@bogon data]# mkdir -p /data/oracle/oracle/product/11.2.0
[root@bogon data]# mkdir /data/oracle/oracle/oradata
[root@bogon data]# mkdir /data/oracle/oracle/inventory
[root@bogon data]# mkdir /data/oracle/oracle/fast_recovery_area
# 修改文件夹从属
[root@bogon data]# chown -R oracle:oinstall /data/oracle/oracle/
# 修改权限
[root@bogon data]# chmod -R 775 /data/oracle/oracle/ ### 10.**配置oracle用户环境变量**
[root@bogon data]# su - oracle
Attempting to create directory /home/oracle/perl5
[oracle@bogon ~]$ vim .bash_profile
# 进入编辑状态后添加如下代码
umask 022
export ORACLE_HOSTNAME=oracle
export ORACLE_BASE=/data/oracle/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/
export ORACLE_SID=ORCL
export PATH=.:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/jdk/bin:$PATH
export LC_ALL="en_US"
export LANG="en_US"
export NLS_LANG="AMERICAN_AMERICA.ZHS16GBK"
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
[oracle@bogon ~]$ source .bash_profile
此步完成建议重启一下服务器，如果未重启，进行下边操作的时候先切换回root用户
11.解压oracle压缩文件，进行安装前的配置
[root@bogon data]# cd /data
[root@bogon data]# unzip linux.x64_11gR2_database_1of2.zip -d /data/oracle/
[root@bogon data]# unzip linux.x64_11gR2_database_2of2.zip -d /data/oracle/
# 解压完成后进行安装前的配置
[root@bogon data]# mkdir /data/oracle/etc
[root@bogon data]# cp /data/oracle/database/response/* /data/oracle/etc/
[root@bogon data]# vim /data/oracle/etc/db_install.rsp
# 进入编辑状态修改如下项的值
oracle.install.option=INSTALL_DB_SWONLY
DECLINE_SECURITY_UPDATES=true
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/data/oracle/oracle/inventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOSTNAME=oracle
ORACLE_HOME=/data/oracle/oracle/product/11.2.0
ORACLE_BASE=/data/oracle/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.isCustomInstall=true
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=dba # 二.安装
1.执行静默安装
su - oracle
cd /data/oracle/database
可以看见database文件夹下有三个模板其中dbca.rsp是用来创建数据库的。db_install.rsp是用来安装Oracle软件的。netca.rsp是用来创建监听器的
./runInstaller -silent -ignorePrereq -responseFile /data/oracle/etc/db_install.rsp
正常会进入如下过程：
最下边一行为日志文件的位置，安装过程中可以通过tail -f xxx.log查看当前日志，当前情况如下
tail -f /data/oracle/oracle/inventory/logs/installActions2019-01-25_10-41-53AM.log
安装成功后情况如下：
在此步骤经常遇到的问题：
centos 安装oracle 报Checking swap space: 0 MB available, 150 MB required. Failed 参考https://www.cnblogs.com/a9999/p/6957280.html
按照上边提示的内容进行操作：
1.打开一个新的shell窗口
2. 登录root账号
3.执行脚本（脚本位置在红框前两行有标注）
4.回到当前窗口按回车
[root@bogon ~]# sh /data/oracle/oracle/inventory/orainstRoot.sh
Changing permissions of /data/oracle/oracle/inventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.
Changing groupname of /data/oracle/oracle/inventory to oinstall.
The execution of the script is complete.
[root@bogon ~]# sh /data/oracle/oracle/product/11.2.0/root.sh
Check /data/oracle/oracle/product/11.2.0/install/root_bogon_2019-01-25_10-51-48.log for the output of root script
2.配置静默监听
在另外一个窗口用root执行那两个脚本后，之前oracle的窗口需要关掉重新开，否则监听配置不成功
[root@bogon ~]# su - oracle
Last login: Fri Jan 25 10:40:23 CST 2019 on pts/0
[oracle@bogon ~]$ netca /silent /responsefile /data/oracle/etc/netca.rsp
Parsing command line arguments:
Parameter "silent" = true
Parameter "responsefile" = /data/oracle/etc/netca.rsp
Done parsing command line arguments.
Oracle Net Services Configuration:
Profile configuration complete.
Listener "LISTENER" already exists.
Oracle Net Services configuration successful. The exit code is 0
3.静默创建数据库
注：修改配置文件为root用户，静默建库为oracle用户
[root@bogon ~]# vim /data/oracle/etc/dbca.rsp
# 修改如下配置
GDBNAME = "orcl"
SID = "orcl"
SYSPASSWORD = "oracle"
SYSTEMPASSWORD = "oracle"
SYSMANPASSWORD = "oracle"
DBSNMPPASSWORD = "oracle"
DATAFILEDESTINATION =/data/oracle/oracle/oradata
RECOVERYAREADESTINATION=/data/oracle/oracle/fast_recovery_area
CHARACTERSET = "AL32UTF8"
TOTALMEMORY = "1638"
修改完成后执行静默建库 GDBNAME为ORCL
[oracle@bogon etc]$ dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbName ORCL -sysPassword oracle -systemPassword oracle ### 4.查看监听状态
[oracle@iz8vb8edqeyilgy4r9zci6z ~]$ lsnrctl status

[oracle@iz8vb8edqeyilgy4r9zci6z ~]$ firewall-cmd --reload
在此步骤经常遇到的问题：

参考https://www.showdoc.cc/page/1932265630854490 参考https://www.cnblogs.com/little-mat/articles/2193767.html
8.强制停止ORACLE数据库
适用场景
shutdown immediate停止数据库失败
# 操作命令
1、kill掉oracle实例相关进程
ps -ef | grep ora_ | grep -v grep | awk '{print $2}' | xargs kill -9
2、清除oracle占用的共享内存段
ipcs -m | grep oracle | grep -v grep | awk '{print $2}' | xargs -n 1 ipcrm -m
3、清除oracle占用的共享信号量
ipcs -s | grep oracle | grep -v grep | awk '{print $2}' | xargs -n 1 ipcrm -s
9.建立测试表空间及账户
create tablespace TMP_LZX datafile '/data/oracle/oracle/oradata/TMP_LZX.dbf' size 50M autoextend on next 5M maxsize 100M;
create user TMP_LZX identified by TMP_LZX default tablespace TMP_LZX;
grant connect,resource,dba,sysdba to TMP_LZX;
三.重启
用root以ssh登录到linux，打开终端输入以下命令：
cd $ORACLE_HOME #进入到oracle的安装目录
dbstart #重启服务器
lsnrctl start #重启监听器
cd $ORACLE_HOME #进入到oracle的安装目录
dbstart #重启服务器
lsnrctl start #重启监听器
四.删除
1、停数据库，关监听
