系统环境准备
开发组件与依赖库安装
安装centos时选择server with gui，右面的可以不勾选，后面统一来装
配置本地yum源
以上包如果缺乏可配置本地yum源进行安装

配置好yum源后开始安装依赖库，如下
|
1
|
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++ |
关闭防火墙

[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. |
关闭selinux
编辑/etc/sysconfig/selinux文件，保存退出后执行 setenforce 0命令
|

vim /etc/sysconfig/selinuxselinux=disabled#selinuxtype=targeted #注释掉 |
创建oracle用户、修改系统参数
创oracle建用户和组

fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 #推荐超过一半的物理内存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 |
通过 /sbin/sysctl -a |grep xxx 查看系统各参数，如果大于官方推荐值不修改，如果小于官方推荐值则修改为官方推荐值，写入/etc/sysctl.conf文件中，使用sysctl -p使其生效，示例如下

[root@localhost etc]# cat sysctl.conffs.aio-max-nr = 6815744kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default = 262144net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1048576 |
修改资源限制如下

[root@localhost etc]# vim /etc/security/limits.conforacle soft nproc 2048oracle hard nproc 16384oracle soft nofile 1024oracle hard nofile 65536oracle soft stack 10240 |
添加以下内容到/etc/pam.d/login
|

|
[root@localhost ~]# vim /etc/pam.d/loginsession required pam_limits.so |
添加以下内容到/etc/profile

[root@localhost ~]# vim /etc/profileif [[ $user = "oracle" ]]; then if [[ $shell = "/bin/ksh" ]]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fifi |
保存后执行source /etc/profile生效
配置oracle用户环境变量，在/home/oracle/.bash_profile中加入如下内容
|

|
[root@localhost ~]# vim /home/oracle/.bash_profileexport oracle_base=/u01/app/oracleexport oracle_home=$oracle_base/product/11.2.0/db_1export oracle_sid=orclexport path=$oracle_home/bin:$oracle_home/opatch:$oracle_home/jdk/bin:$pathexport lang="en_us.utf-8"export nls_lang=american_america.utf8export nls_date_format="yyyy-mm-dd hh24:mi:ss" |
创建oracle安装目录
|
1
2
3
|
mkdir -p /u01/app/oracle/product/11.2.0/db_1chown -r oracle:oinstall /u01/appchmod -r 775 /u01/app |
安装oracle 11g
挂载oracle11g安装包iso（也可以通过其他方式将oracle安装包传到主机），将安装文件复制到oracle home目录下，修改文件权限给oracle用户
|

6
|
[root@localhost /]# mkdir /mnt/oracle11g[root@localhost /]# mount /dev/cdrom /mnt/oracle11g/[root@localhost /]# cp -r /mnt/oracle11g /home/oracle/# 复制到oracle home目录下并修改权限[root@localhost oracle]# chown -r oracle:oinstall /home/oracle/oracle11g/[root@localhost oracle]# chmod -r 775 /home/oracle/oracle11g/ |
接下来使用oracle用户登录桌面
执行./runinstaller开始安装，centos 7安装的时候错误弹框有时候会变成一条竖线，安装无法进行下去，所以运行时执行
|
1
|
./runinstaller -jreloc /etc/alternatives/jre_1.8.0 |
每项操作如下
[configure security updates] 取消勾选 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，开始安装oracle 11g
安装到84%的时候可能会出现ins_ctx.mk相关的错误，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)# 修改为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: $(mk_emagent_nmectl)# 修改为$(sysmanbin)emdctl: $(mk_emagent_nmectl) -lnnz11 |
retry继续安装到94%时，弹出
使用root用户ssh到主机到上述目录分别执行orainstroot.sh与root.sh，执行root.sh时根据提示填入路径
/u01/app/oracle/product/11.2.0/dbhome_1/bin，执行完成后到ui点击ok，安装完成
环境配置脚本
- 使用root用户登录
- 确保系统iso驱动器已连接（/dev/cdrom可mount）
- 复制脚本到主机并给予可执行权限，执行脚本完成后即可开始安装oracle 11g
