1.查看swap大小，若小於150M，需添加增加虛擬空間
dd if=/dev/zero of=/swapadd bs=1024 count=2006424
mkswap /swapadd
swapon /swapadd
重啟系統虛擬空間會消失，除非打開/etc/fstab文件，加入
/swap swap swap default 0 0
2.查看操作系統信息
[root@docker ~]# uname -m
x86_64
[root@docker ~]# cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)
3.安裝前的准備
a.修改主機名，linux7以上系統用：hostnamectl set-hostname hostname
4.關閉selinux：vi /etc/selinux/config，設置如下，重啟系統reboot；
5.檢查以下服務是否安裝
binutils-2.23.52.0.1-12.el7.x86_64 compat-libcap1-1.10-3.el7.x86_64 compat-libstdc++-33-3.2.3-71.el7.i686 compat-libstdc++-33-3.2.3-71.el7.x86_64 gcc-4.8.2-3.el7.x86_64 gcc-c++-4.8.2-3.el7.x86_64 glibc-2.17-36.el7.i686 glibc-2.17-36.el7.x86_64 glibc-devel-2.17-36.el7.i686 glibc-devel-2.17-36.el7.x86_64 ksh libaio-0.3.109-9.el7.i686 libaio-0.3.109-9.el7.x86_64 libaio-devel-0.3.109-9.el7.i686 libaio-devel-0.3.109-9.el7.x86_64 libgcc-4.8.2-3.el7.i686 libgcc-4.8.2-3.el7.x86_64 libstdc++-4.8.2-3.el7.i686 libstdc++-4.8.2-3.el7.x86_64 libstdc++-devel-4.8.2-3.el7.i686 libstdc++-devel-4.8.2-3.el7.x86_64 libXi-1.7.2-1.el7.i686 libXi-1.7.2-1.el7.x86_64 libXtst-1.2.2-1.el7.i686 libXtst-1.2.2-1.el7.x86_64 make-3.82-19.el7.x86_64 sysstat-10.1.5-1.el7.x86_64 unixODBC-2.3.1-6.el7.x86_64 or later unixODBC-2.3.1-6.el7.i686 or later unixODBC-devel-2.3.1-6.el7.x86_64 or later unixODBC-devel-2.3.1-6.el7.i686 or later
若擔心系統包比較舊可考慮先更新程序包：yum -y upgrade，（提示：等待時間比較長！）
用yum進行安裝所需服務：
yum -y install binutils compat-libcap1 compat-libstdc++-33 compat-libstdc++-33*i686 compat-libstdc++-33*.devel compat-libstdc++-33 compat-libstdc++-33*.devel gcc gcc-c++ glibc glibc*.i686 glibc-devel glibc-devel*.i686 ksh libaio libaio*.i686 libaio-devel libaio-devel*.devel libgcc libgcc*.i686 libstdc++ libstdc++*.i686 libstdc++-devel libstdc++-devel*.devel libXi libXi*.i686 libXtst libXtst*.i686 make sysstat unixODBC unixODBC*.i686 unixODBC-devel unixODBC-devel*.i686
檢查31個包是否都有安裝，版本號只能大於規定的版本，不能小於
rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel

6.創建oinstall和dba組
/usr/sbin/groupadd oinstall /usr/sbin/groupadd dba
7.創建Oracle用戶：
/usr/sbin/useradd -g oinstall -G dba oracle
設置oracle密碼
passwd oracle
驗證創建及所屬組是否正確：id oracle
[root@docker ~]# id oracle uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba)
8.配置內核參數
[root@docker ~]# vim /etc/sysctl.conf # System default settings live in /usr/lib/sysctl.d/00-system.conf. # To override those settings, enter new settings here, or in an /etc/sysctl.d/<name>.conf file # # For more information, see sysctl.conf(5) and sysctl.d(5). fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 7516192768 #7G
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 = 1048576
參數的值不能小於上面的配置，因為這是oracle官方建議的最小值，所以生產環境建議調整為這些參數，以優化系統性能。
注意：kernel.shmmax的值，#最低：536870912，最大值：比物理內存小1個字節的值，建議比物理內存小一點點就可以（過小的話后期會導致數據庫實例無法啟動或無法監聽）
參數解釋：
shmmax=物理內存*80%*80%，單位是字節 kernel.shmmax：表示單個共享內存段的最大值，以字節為單位，此值一般為物理內存的一半，不過大一點也沒關系，這里設定的為4GB，即“4294967295/1024/1024/1024=4G”。 kernel.shmmin：表示單個共享內存段的最小值，默認為1byte kernel.shmall：表示整個系統范圍內可用共享內存頁的總量，單位是頁（page），在32位系統上一頁等於4kB，也就是4096字節。計算公式是：shmmax/PAGE_SIZE kernel.shmmni：表示整個系統范圍內內存段的最大數量，一般為4096. ip_local_port_range ：表示端口的范圍。在監聽器幫助客戶端進程和服務器進程建立連接時，會用到指定范圍內的端口。 kernel.sem ：表示設置的信號量，這4個參數內容大小固定。 net.core.rmem_default ：表示接收套接字緩沖區大小的缺省值（以字節為單位）。 net.core.rmem_max ：表示接收套接字緩沖區大小的最大值（以字節為單位） net.core.wmem_default ：表示發送套接字緩沖區大小的缺省值（以字節為單位）。 net.core.wmem_max ：表示發送套接字緩沖區大小的最大值（以字節為單位）。
修改后使之生效
/sbin/sysctl -p
9.修改用戶權限
vim /etc/security/limits.conf #在末尾添加 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240 oracle hard stack 10240
10.在/etc/pam.d/login 文件中，使用文本編輯器或vi命令增加或修改以下內容
session required /lib64/security/pam_limits.so session required pam_limits.so
11.在/etc/profile 文件中，使用文本編輯器或vi命令增加或修改以下內容
if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536
else ulimit -u 16384 -n 65536 fi fi
使之生效：source /etc/profile
source /etc/profile
12.創建安裝目錄
mkdir -p /data/oracle/app/ chown -R oracle:oinstall /data/oracle/app/ chmod -R 775 /data/oracle/app/
#提示：圖型化界面安裝需創建 oraInventory目錄
mkdir -p /data/oracle oraInventory chown -R oracle:oinstall /data/oraInventory chmod -R 775 /data/oraInventory
13.配置環境變量
[oracle@docker ~]$ vim ~/.bash_profile export ORACLE_BASE=/data/app/oracle export ORACLE_SID=dbsrv2
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
PATH=$PATH:$ORACLE_HOME/bin
使之生效
source ~/.bash_profile
14.解壓oracle軟件
[root@docker src]# unzip linux.x64_11gR2_database_1of2.zip
[root@docker src]# unzip linux.x64_11gR2_database_2of2.zip
15.切換到Oracle用戶，復制響應文件模板
[oracle@docker ~]$ mkdir etc [oracle@docker ~]$ cp /usr/local/src/database/response/* /home/oracle/etc/ [oracle@docker ~]$ ls etc dbca.rsp db_install.rsp netca.rsp
16.設置響應文件權限
[oracle@docker ~]$ su - root [root@docker ~]# chmod 700 /home/oracle/etc/*.rsp
17.切換到oracle用戶：su - oracle，修改安裝Oracle軟件的響應文件/home/oracle/etc/db_install.rsp
oracle.install.option=INSTALL_DB_SWONLY // 安裝類型
ORACLE_HOSTNAME=docker // 主機名稱（hostname查詢）
UNIX_GROUP_NAME=oinstall // 安裝組
INVENTORY_LOCATION=/u01/app/oraInventory //INVENTORY目錄（不填就是默認值）
SELECTED_LANGUAGES=en,zh_CN,zh_TW // 選擇語言
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 //oracle_home
ORACLE_BASE=/u01/app/oracle //oracle_base
oracle.install.db.InstallEdition=EE // oracle版本
oracle.install.db.EEOptionsSelection=false //自定義安裝，否，使用默認組件
oracle.install.db.DBA_GROUP=dba / / dba用戶組 oracle.install.db.OPER_GROUP=oinstall // oper用戶組
oracle.install.db.config.starterdb.type=GENERAL_PURPOSE //數據庫類型
oracle.install.db.config.starterdb.globalDBName=orcl //globalDBName
oracle.install.db.config.starterdb.SID=dbsrv2 //SID
oracle.install.db.config.starterdb.memoryLimit=81920 //自動管理內存的內存(M)
oracle.install.db.config.starterdb.password.ALL=oracle //設定所有數據庫用戶使用同一個密碼
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false //（手動寫了false）
DECLINE_SECURITY_UPDATES=true //設置安全更新（貌似是有bug，這個一定要選true，否則會無限提醒郵件地址有問題，終止安裝。PS：不管地址對不對）
18.開始靜默安裝
[oracle@docker database]$ /data/software//database/runInstaller -silent -responseFile /home/oracle/etc/db_install.rsp
19.查看安裝日志
tail -f /u01/app/oraInventory/logs/installActions2016-08-31_06-56-29PM.log
出現如下提示表示安裝完成
[oracle@zyadmin ~]$ /data/software//database/runInstaller -silent -responseFile /home/oracle/etc/db_install.rsp 正在啟動 Oracle Universal Installer... 檢查臨時空間: 必須大於 120 MB。 實際為 33493 MB 通過 檢查交換空間: 必須大於 150 MB。 實際為 1959 MB 通過 准備從以下地址啟動 Oracle Universal Installer /tmp/OraInstall2018-08-18_03-29-11PM. 請稍候...[oracle@zyadmin ~]$ [WARNING] [INS-13014] 目標環境不滿足一些可選要求。 原因: 不滿足一些可選的先決條件。有關詳細信息, 請查看日志。/tmp/OraInstall2018-08-18_03-29-11PM/installActions2018-08-18_03-29-11PM.log 操作: 從日志 /tmp/OraInstall2018-08-18_03-29-11PM/installActions2018-08-18_03-29-11PM.log 中確定失敗的先決條件檢查列表。然后, 從日志文件或安裝手冊中查找滿足這些先決條件的適當配置, 並手動進行修復。 可以在以下位置找到本次安裝會話的日志: /data/u01/app/oraInventory/logs/installActions2018-08-18_03-29-11PM.log ^C [oracle@zyadmin ~]$ tail /data/u01/app/oraInventory/logs/installActions2018-08-18_03-29-11PM.log 信息: 構建客戶機共享庫 信息: 此 make 操作的輸出也可以在以下位置獲得: '/data/u01/app/oracle/product/11.2.0/db_1/install/make.log' 信息: 信息: 開始從衍生進程輸出: 信息: ---------------------------------- 信息: 信息: /data/u01/app/oracle/product/11.2.0/db_1/bin/genclntsh [oracle@zyadmin ~]$ Oracle Database 11g 的 安裝 已成功。 請查看 '/data/u01/app/oraInventory/logs/silentInstall2018-08-18_03-29-11PM.log' 以獲取詳細資料。 以 root 用戶的身份執行以下腳本: 1. /data/u01/app/oraInventory/orainstRoot.sh 2. /data/u01/app/oracle/product/11.2.0/db_1/root.sh Successfully Setup Software.
20.使用root用戶執行腳本
su - root /u01/app/oraInventory/orainstRoot.sh /u01/app/oracle/product/11.2.0/db_1/root.sh
常見報錯解決辦法：
（1）若沒有生成orainstRoot.sh這個文件，解決辦法：刪除/etc/oraInst.loc文件
（2） 若重裝Oracle提示：“系統標識符（SID）已經存在，請指定另一個SID”，
解決辦法：把/etc/oratab里面對應的記錄注釋或者刪除掉
(3)修改Oracle端口：
a.查看監聽狀態，停止監聽 $lsnrctl status $lsnrctl stop b.修改配置文件 $vi $ORACLE_HOME/network/admin/listener.ora (修改對應的端口為欲更改端口) c.登陸並查看local_listener參數 $sqlplus / as sysdba >show parameter local_listener (此時value值是空的) d.修改local_listener參數 >alter system set local_listener="(address=(protocol=tcp)(host=172.16.8.129)(port=1521))"; （host后面加主機名或者IP，然后就可以查看local_listener參數了） e.啟動監聽，查看狀態 >lsnrctl start >lsnrctl status f.防火牆端口開放 # /sbin/iptables -l INPUT -p tcp --dport 端口 -j ACCEPT # /etc/rc.d/init.d/iptables save
a.查看監聽狀態，停止監聽
$lsnrctl status
$lsnrctl stop
b.修改配置文件
$vi $ORACLE_HOME/network/admin/listener.ora
(修改對應的端口為欲更改端口)
c.登陸並查看local_listener參數
$sqlplus / as sysdba
>show parameter local_listener
(此時value值是空的)
d.修改local_listener參數
>alter system set local_listener="(address=(protocol=tcp)(host=172.16.8.129)(port=1521))";
（host后面加主機名或者IP，然后就可以查看local_listener參數了）
e.啟動監聽，查看狀態
>lsnrctl start
>lsnrctl status
f.防火牆端口開放
# /sbin/iptables -l INPUT -p tcp --dport 端口 -j ACCEPT
# /etc/rc.d/init.d/iptables save
21.增加或修改oracle的環境變量
su - oracle vim ~/.bash_profile #for oracle export ORACLE_BASE=/u01/app/oracle export ORACLE_SID=dbsrv2 export ROACLE_PID=ora11g #export NLS_LANG=AMERICAN_AMERICA.AL32UTF8 export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 export PATH=$PATH:$ORACLE_HOME/bin export LANG="zh_CN.UTF-8" export NLS_LANG="SIMPLIFIED CHINESE_CHINA.AL32UTF8" export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
22.配置監聽程序：netca /silent /responsefile /home/oracle/etc/netca.rsp
[oracle@docker ~]$ netca /silent /responsefile /home/oracle/etc/netca.rsp Parsing command line arguments: Parameter "silent" = true Parameter "responsefile" = /home/oracle/etc/netca.rsp Done parsing command line arguments.

24.靜默dbca建庫，編輯應答文件
[oracle@docker ~]$ vi etc/dbca.rsp [GENERAL] RESPONSEFILE_VERSION = "11.2.0" OPERATION_TYPE = "createDatabase" [CREATEDATABASE] GDBNAME = "dbsrv2" SID = "dbsrv2" TEMPLATENAME = "General_Purpose.dbc" CHARACTERSET = "AL32UTF8"
25.建庫：
[oracle@docker ~]$ dbca -silent -responseFile etc/dbca.rsp
[oracle@docker ~]$ dbca -silent -responseFile etc/dbca.rsp Enter SYS user password: Enter SYSTEM user password: sh: /bin/ksh: No such file or directory sh: /bin/ksh: No such file or directory Copying database files 1% complete 3% complete 11% complete 18% complete 26% complete 37% complete Creating and starting Oracle instance 40% complete 45% complete 50% complete 55% complete 56% complete 57% complete 60% complete 62% complete Completing Database Creation 66% complete 70% complete 73% complete 74% complete 85% complete 96% complete 100% complete Look at the log file Look at the log file "/u01/app/oracle/cfgtoollogs/dbca/orcl11g/orcl11g.log" for further details.
