1.檢視swap大小，若小於150M，需新增增加虛擬空間
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，除非開啟/etc/fstab檔案，加入/swap swap swap default 0 0
2.檢視作業系統資訊
[[email protected] ~]# uname -m
x86_64
[[email protected] ~]# cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)
3.安裝前的準備
a.修改主機名，linux7以上系統用：hostnamectl set-hostname hostname
4.關閉selinux：vi /etc/selinux/config，設定如下，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++-4.8View Code.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
若擔心繫統包比較舊可考慮先更新程式包：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.建立oinstall和dba組
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
7.建立Oracle使用者
/usr/sbin/useradd -g oinstall -G dba oracle
8.設定oracle密碼
passwd oracle
9.驗證建立及所屬組是否正確：id oracle
[[email protected] ~]# id oracle
uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba)
10.配置核心引數
[[email protected] ~]# 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 #7Gkernel.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
引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引數，以優化系統性能。
注意：kernel.shmmax的值，#最低：536870912，最大值：比實體記憶體小1個位元組的值，建議比實體記憶體小一點點就可以（過小的話後期會導致資料庫例項無法啟動或無法監聽）
引數解釋：
shmmax=實體記憶體*80%*80%，單位是位元組 kernel.shmmax：表示單個共享記憶體段的最大值，以位元組為單位，此值一般為實體記憶體的一半，不過大一點也沒關係，這裡設定的為4GB，即“4294967295/1024/1024/1024=4G”。 kernel.shmmin：表示單個共享記憶體段的最小值，預設為1byte kernel.shmall：表示整個系統範圍內可用共享記憶體頁的總量，單位是頁（page），在32位系統上一頁等於4kB，也就是4096位元組。計算公式是：shmmax/PAGE_SIZE kernel.shmmni：表示整個系統範圍內記憶體段的最大數量，一般為4096. ip_local_port_range ：表示埠的範圍。在監聽器幫助客戶端程序和伺服器程序建立連線時，會用到指定範圍內的埠。 kernel.sem ：表示設定的訊號量，這4個引數內容大小固定。 net.core.rmem_default ：表示接收套接字緩衝區大小的預設值（以位元組為單位）。 net.core.rmem_max ：表示接收套接字緩衝區大小的最大值（以位元組為單位） net.core.wmem_default ：表示傳送套接字緩衝區大小的預設值（以位元組為單位）。 net.core.wmem_max ：表示傳送套接字緩衝區大小的最大值（以位元組為單位）。引數解釋
修改後使之生效
/sbin/sysctl -p
11.修改使用者許可權
vim /etc/security/limits.conf
#在末尾新增
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 10240
12.在/etc/pam.d/login 檔案中，使用文字編輯器或vi命令增加或修改以下內容
session required /lib64/security/pam_limits.so
session required pam_limits.so
13.在/etc/profile 檔案中，使用文字編輯器或vi命令增加或修改以下內容
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
使之生效：source /etc/profile
source /etc/profile
14.建立安裝目錄
mkdir -p /u01/app/
chown -R oracle:oinstall /u01/app/
chmod -R 775 /u01/app/
15.配置環境變數
[[email protected] ~]$ vim ~/.bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=dbsrv2
使之生效
source ~/.bash_profile
16.解壓oracle軟體
[[email protected] src]# unzip linux.x64_11gR2_database_1of2.zip
[[email protected] src]# unzip linux.x64_11gR2_database_2of2.zip
17.切換到Oracle使用者，複製響應檔案模板
[[email protected] ~]$ mkdir etc
[[email protected] ~]$ cp /usr/local/src/database/response/* /home/oracle/etc/
[[email protected] ~]$ ls etc
dbca.rsp db_install.rsp netca.rsp
18.設定響應檔案許可權
[[email protected] ~]$ su - root
[[email protected] ~]# chmod 700 /home/oracle/etc/*.rsp
19.切換到oracle使用者：su - oracle，修改安裝Oracle軟體的響應檔案/home/oracle/etc/db_install.rsp
oracle.install.option=INSTALL_DB_SWONLY // 安裝型別
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（不填就是預設值）
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，使用預設元件
oracle.install.db.DBA_GROUP=dba / / dba使用者組
oracle.install.db.OPER_GROUP=oinstall // oper使用者組
oracle.install.db.config.starterdb.type=GENERAL_PURPOSE //資料庫型別
oracle.install.db.config.starterdb.globalDBName=orcl //globalDBName
oracle.install.db.config.starterdb.SID=dbsrv2 //SID
oracle.install.db.config.starterdb.memoryLimit=81920 //自動管理記憶體的記憶體(M)
oracle.install.db.config.starterdb.password.ALL=oracle //設定所有資料庫使用者使用同一個密碼
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false //（手動寫了false）
DECLINE_SECURITY_UPDATES=true //設定安全更新（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）
20.開始靜默安裝
[[email protected] database]$ /data/software//database/runInstaller -silent -responseFile /home/oracle/etc/db_install.rsp
21.檢視安裝日誌
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
[[email protected] ~]$ /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 準備從以下地址啟動 Oracle Universal Installer /tmp/OraInstall2018-08-18_03-29-11PM. 請稍候...[[email protected] ~]$ [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。有關詳細資訊, 請檢視日誌。/tmp/OraInstall2018-08-18_03-29-11PM/installActions2018-08-18_03-29-11PM.log 操作: 從日誌 /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。然後, 從日誌檔案或安裝手冊中查詢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誌: /data/u01/app/oraInventory/logs/installActions2018-08-18_03-29-11PM.log ^C [[email protected] ~]$ tail /data/u01/app/oraInventory/logs/installActions2018-08-18_03-29-11PM.log 資訊: 構建客戶機共享庫 資訊: 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' 資訊: 資訊: 開始從衍生程序輸出: 資訊: ---------------------------------- 資訊: 資訊: /data/u01/app/oracle/product/11.2.0/db_1/bin/genclntsh [[email protected] ~]$ Oracle Database 11g 的 安裝 已成功。 請檢視 '/data/u01/app/oraInventory/logs/silentInstall2018-08-18_03-29-11PM.log' 以獲取詳細資料。 以 root 使用者的身份執行以下指令碼: 1. /data/u01/app/oraInventory/orainstRoot.sh 2. /data/u01/app/oracle/product/11.2.0/db_1/root.sh Successfully Setup Software.View Code
22.使用root使用者執行指令碼
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這個檔案，解決辦法：刪除/etc/oraInst.loc檔案
（2） 若重灌Oracle提示：“系統識別符號（SID）已經存在，請指定另一個SID”，
解決辦法：把/etc/oratab裡面對應的記錄註釋或者刪除掉
(3)修改Oracle埠：
a.檢視監聽狀態，停止監聽 $lsnrctl status $lsnrctl stop b.修改配置檔案 $vi $ORACLE_HOME/network/admin/listener.ora (修改對應的埠為欲更改埠) c.登陸並檢視local_listener引數 $sqlplus / as sysdba >show parameter local_listener (此時value值是空的) d.修改local_listener引數 >alter system set local_listener="(address=(protocol=tcp)(host=172.16.8.129)(port=1521))"; （host後面加主機名或者IP，然後就可以檢視local_listener引數了） e.啟動監聽，檢視狀態 >lsnrctl start >lsnrctl status f.防火牆埠開放 # /sbin/iptables -l INPUT -p tcp --dport 埠 -j ACCEPT # /etc/rc.d/init.d/iptables saveView Code
a.檢視監聽狀態，停止監聽
$lsnrctl status
$lsnrctl stop
b.修改配置檔案
$vi $ORACLE_HOME/network/admin/listener.ora
(修改對應的埠為欲更改埠)
c.登陸並檢視local_listener引數
$sqlplus / as sysdba
>show parameter local_listener
(此時value值是空的)
d.修改local_listener引數
>alter system set local_listener="(address=(protocol=tcp)(host=172.16.8.129)(port=1521))";
（host後面加主機名或者IP，然後就可以檢視local_listener引數了）
e.啟動監聽，檢視狀態
>lsnrctl start
>lsnrctl status
f.防火牆埠開放
# /sbin/iptables -l INPUT -p tcp --dport 埠 -j ACCEPT
# /etc/rc.d/init.d/iptables save
23.增加或修改oracle的環境變數
su - oracle
vim ~/.bash_profile
#for oracle
