系統環境準備
開發組件與依賴庫安裝
安裝centos時選擇Server with GUI，右面的可以不勾選，后面統一來裝
配置本地yum源
以上包如果缺乏可配置本地yum源進行安裝
sudo mount /dev/cdrom /mnt/
[galen@localhost yum.repos.d]$ sudo vim /etc/yum.repos.d/cdrom.repo
[galen@localhost yum.repos.d]$ cat cdrom.repo
[c7-media]
name=isofile
baseurl=file:///mnt
enable=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
[galen@localhost yum.repos.d]$ sudo mv CentOS-Base.repo CentOS-Base.repo-bak
[galen@localhost yum.repos.d]$ sudo mv CentOS-Media.repo CentOS-Media.repo-bak
[galen@localhost yum.repos.d]$ sudo mv cdrom.repo CentOS-Media.repo
配置好yum源后開始安裝依賴庫，如下
yum install glibc glibc-devel glibc-headers ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh compat-libcap1 compat-libstdc++ elfutils-libelf-devel gcc-c++
關閉防火墻
[galen@localhost ~]$ systemctl stop firewalld.service
[galen@localhost ~]$ systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
關閉selinux
編輯/etc/sysconfig/selinux文件，保存退出后執行 setenforce 0命令
vim /etc/sysconfig/selinux
SELINUX=disabled
#SELINUXTYPE=targeted #注釋掉
創建oracle用戶、修改系統參數
創oracle建用戶和組
[root@localhost galen]# groupadd oinstall
[root@localhost galen]# groupadd dba
[root@localhost galen]# useradd -g oinstall -G dba oracle
[root@localhost galen]# passwd oracle
[root@localhost galen]# id oracle
uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba)
系統參數設置
官方推薦值：
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912 #推薦超過一半的物理內存
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
通過 /sbin/sysctl -a |grep xxx 查看系統各參數，如果大于官方推薦值不修改，如果小于官方推薦值則修改為官方推薦值，寫入/etc/sysctl.conf文件中，使用sysctl -p使其生效，示例如下
[root@localhost etc]# cat sysctl.conf
fs.aio-max-nr = 6815744
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
修改資源限制如下
[root@localhost etc]# vim /etc/security/limits.conf
oracle soft nproc 2048
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
添加以下內容到/etc/pam.d/login
[root@localhost ~]# vim /etc/pam.d/login
session required pam_limits.so
添加以下內容到/etc/profile
[root@localhost ~]# vim /etc/profile
if [[ $USER = "oracle" ]]; then
if [[ $SHELL = "/bin/ksh" ]]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
保存后執行source /etc/profile生效
配置oracle用戶環境變量，在/home/oracle/.bash_profile中加入如下內容
[root@localhost ~]# vim /home/oracle/.bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_SID=orcl
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/jdk/bin:$PATH
export LANG="en_US.UTF-8"
export NLS_LANG=american_AMERICA.UTF8
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
創建oracle安裝目錄
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01/app
chmod -R 775 /u01/app
安裝oracle 11g
掛載oracle11g安裝包iso（也可以通過其他方式將oracle安裝包傳到主機），將安裝文件復制到oracle home目錄下，修改文件權限給oracle用戶
[root@localhost /]# mkdir /mnt/oracle11g
[root@localhost /]# mount /dev/cdrom /mnt/oracle11g/
[root@localhost /]# cp -r /mnt/oracle11g /home/oracle/
# 復制到oracle home目錄下并修改權限
[root@localhost oracle]# chown -R oracle:oinstall /home/oracle/oracle11g/
[root@localhost oracle]# chmod -R 775 /home/oracle/oracle11g/
接下來使用oracle用戶登錄桌面
執行./runInstaller開始安裝，Centos 7安裝的時候錯誤彈框有時候會變成一條豎線，安裝無法進行下去，所以運行時執行
./runInstaller -jreLoc /etc/alternatives/jre_1.8.0
每項操作如下
[Configure Security Updates] 取消勾選 I wish to receive security updates via My Oracle Support，Next
[Installation Option] Install database software only，Next
[Grid Options] Next
[Product Languages] Next
[Enterprise Edition] Next
[Installation Location] Next
[Create Inventory] Next
[Operating System Groups] Next
[Prerequisite Checks] Next
[Summary] Finish，開始安裝oracle 11g
安裝到84%的時候可能會出現ins_ctx.mk相關的錯誤，如下
修改/u01/app/oracle/product/11.2.0/db_1/ctx/lib/ins_ctx.mk文件
# 源文件
ctxhx: $(CTXHXOBJ)
$(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK)
# 修改為
ctxhx: $(CTXHXOBJ)
-static $(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK) /usr/lib64/stdc.a
修改/u01/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk文件
# 源文件
$(SYSMANBIN)emdctl:
$(MK_EMAGENT_NMECTL)
# 修改為
$(SYSMANBIN)emdctl:
$(MK_EMAGENT_NMECTL) -lnnz11
retry繼續安裝到94%時，彈出
使用root用戶ssh到主機到上述目錄分別執行orainstRoot.sh與root.sh，執行root.sh時根據提示填入路徑
/u01/app/oracle/product/11.2.0/dbhome_1/bin，執行完成后到UI點擊OK，安裝完成
環境配置腳本
- 使用root用戶登錄
- 確保系統iso驅動器已連接（/dev/cdrom可mount）
- 復制腳本到主機并給予可執行權限，執行腳本完成后即可開始安裝oracle 11g
