安装环境:CentOS 7(64位) 、 oracle11G 的压缩包
第一步:创建相关目录,并将安装包放在指定路径下
[root@localhost data]# pwd /data [root@localhost data]# ll total 0 drwxr-xr-x. 2 root root 6 Sep 27 00:42 oracle //安装目录 drwxrwxr-x. 2 root root 6 Sep 27 00:25 oradata //配置文件 drwxrwxr-x. 2 root root 88 Sep 26 23:53 soft //压缩包目录
第二步:创建相关用户组和密码(密码提示过于简单之类的话请不用管它)
[root@localhost soft]# groupadd oinstall [root@localhost soft]# groupadd dba[root@localhost soft]# useradd -g oinstall -g dba -m oracle //用户既属于oinstall又属于dba [root@localhost soft]# passwd oracle Changing password for user oracle.New password: BAD PASSWORD: The password fails the dictionary check - it is too simplistic/systematicRetype new password: passwd: all authentication tokens updated successfully.
第三步:赋值
chmod -R 775 /data/chown -R oracle.oinstall /data/oracle/ chown -R oracle:oinstall /data/soft/ chown -R oracle:oinstall /data/oradata/chmod -R 775 /data/oracle/ [root@localhost soft]# chown -R oracle:oinstall database/ //将解压后的database目录也赋给oracle [root@localhost soft]# ll total 2295592 drwxr-xr-x. 8 oracle oinstall 128 Aug 20 2009 database -rwxrwxr-x. 1 oracle oinstall 1239269270 Apr 23 2013 linux.x64_11gR2_database_1of2.zip -rwxrwxr-x. 1 oracle oinstall 1111416131 Apr 23 2013 linux.x64_11gR2_database_2of2.zip
第四步:修改标识
[root@localhost data]# vi /etc/redhat-release [root@localhost data]# cat /etc/redhat-releaseredhat-7
第五步:安装相关软件包
yum -y install binutils* compat-libcap1* compat-libstdc++* gcc* gcc-c++* glibc* glibc-devel* ksh* libaio* libaio-devel* libgcc* libstdc++* libstdc++-devel* libXi* libXtst* make* sysstat* elfutils* unixODBC*
第六步:防火墙问题
systemctl status firewalld.service systemctl disable firewalld.service
第七步:修改selinux
vi /etc/selinux/config 如下图所示,将selinux设置为disabled状态
第八步:修改 linux 内核
vi /etc/sysctl.conf 添加以下内容: net.ipv4.icmp_echo_ignore_broadcasts = 1 net.ipv4.conf.all.rp_filter = 1 fs.file-max = 6815744 fs.aio-max-nr = 1048576 kernel.shmall = 2097152 kernel.shmmax = 2147483648 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 配置生效:[root@localhost data]# sysctl -p
第九步: 修改用户的 SHELL 的限制
(1)vi /etc/security/limits.conf 添加以下内容: * soft nproc 2047 * hard nproc 16384 * soft nofile 1024 * hard nofile 65536 (2)修改/etc/pam.d/login 文件,vi /etc/pam.d/login 添加: session required /lib64/security/pam_limits.so session required pam_limits.so (3)编辑 /etc/profile ,vi /etc/profile 添加: if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi
第十步:修改配置文件
[root@localhost data]# su - oracle [oracle@localhost ~]$ export LANG=en_US //把语言环境改为英文 vi /home/oracle/.bash_profile 添加: export PATH export ORACLE_BASE=/data/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2 export ORACLE_SID=orcl export PATH=$PATH:$ORACLE_HOME/bin:/usr/bin:/usr/sbin:/usr/lib export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data 生效:source /home/oracle/.bash_profile 设置主机 hosts 文件,vi /etc/hosts 添加自己主机ip信息,例如: 192.168.113.133 localhost localhost.localdomain localhost4 localhost4.localdomain4
第十一步:
[oracle@localhost database]$ ./runInstaller
后面图形化部分由于图片太大,不一一列举,多数为next。(可见其他博客说明)
安装好后输入dbca,继续图形化界面安装。
第十二步:数据库的启动、关闭
---------启动监听服务-------------
# su – oracle
$ lsnrctl LSNRCTL> status LSNRCTL> start LSNRCTL> exit[oracle@redhat64 ~]$ export oracle_sid=orcl //实例名用之前图形界面设置的
---------启动------------
[oracle@redhat64 ~]$ sqlplus / as sysdba
SQL> startup-------关闭--------------
# su – oracle
$ sqlplus / as sysdba SQL> shutdown immediate
