RHEL6U3安装64bitOracle11gR2

今天接到通知，下周去一个新客户那边部署新环境，问题是时间还很紧，让下周一就去，时间紧还不是大问题，问题是产品的中间件Weblogic跟数据库Oracle我都好久没玩

今天接到通知，下周去一个新客户那边部署新环境，问题是时间还很紧，让下周一就去，时间紧还不是大问题，问题是产品的中间件Weblogic跟数据库Oracle我都好久没玩了，没得办法，只能提前演练一下了，为了下次找起来更加方便，就把过程整理到本博客上面来，也可以方便其他童鞋的查询吧。

谁要是跟我纠结时间这么紧，哪来的时间写博客的，我跟谁急哦！方便自己，也方便大家嘛！

华丽分割线

一.查看系统配置信息

[root@web-db ~]# hostname --fqdn //查看主机名 web-db [root@web-db ~]# ifconfig eth0 //查看本机IP地址 eth0 Link encap:Ethernet HWaddr 06:F1:96:00:00:C0 inet addr:192.168.153.153 Bcast:192.168.153.255 Mask:255.255.255.0 inet6 addr: fe80::4f1:96ff:fe00:c0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1706513 errors:0 dropped:0 overruns:0 frame:0 TX packets:877952 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2565533900 (2.3 GiB) TX bytes:59768622 (56.9 MiB) [root@web-db ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.153.153 web-db [root@web-db ~]# cat /etc/redhat-release //查看RHEL发行版本 Red Hat Enterprise Linux Server release 6.3 (Santiago) [root@web-db ~]# uname -m //查看本机CPU架构 x86_64 [root@web-db ~]# free -m //查看内存跟交换分区信息 total used free shared buffers cached Mem: 7870 2876 4993 0 12 2609 -/+ buffers/cache: 254 7616 Swap: 5760 0 5760 [root@web-db ~]# df -H //查看分区挂载信息 Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root 9.1G 3.6G 5.1G 41% / tmpfs 4.2G 0 4.2G 0% /dev/shm /dev/vda1 508M 33M 449M 7% /boot /dev/vdb5 30G 181M 28G 1% /u01

当然，有朋友会问：你用的是物理机还是虚拟机？

我这么有钱，想想就知道我用的是什么了，是不是？

[root@web-db ~]# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 8 On-line CPU(s) list: 0-7 Thread(s) per core: 1 Core(s) per socket: 1 CPU socket(s): 8 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 13 Stepping: 3 CPU MHz: 2393.998 BogoMIPS: 4787.99 Hypervisor vendor: KVM Virtualization type: full L1d cache: 32K L1i cache: 32K L2 cache: 4096K NUMA node0 CPU(s): 0-7

咦？ 怎么不是物理机，我说我什么时候这么有钱的呢？用的还是KVM虚拟机。

呵呵，开个玩笑，我们继续技术交流，禁止鄙视使用虚拟机的屌丝！

二.配置系统YUM源，安装依赖包

[root@web-db ~]# mount /dev/sr0 /media/ mount: block device /dev/sr0 is write-protected, mounting read-only [root@web-db ~]# cat /etc/yum.repos.d/rhel-source.repo [rhel6u3-core] name=rhel6u3-core baseurl=file:///media enabled=1 gpgcheck=0[root@web-db ~]# yum clean all Loaded plugins: product-id, subscription-manager Updating certificate-based repositories. Unable to read consumer identity Cleaning repos: rhel6u3-core Cleaning up Everything[root@web-db ~]# cat package.list //需要安装的依赖包信息列表 binutils compat-libcap1 compat-libstdc++-33 compat-libstdc++-33*.i686 elfutils-libelf-devel gcc gcc-c++ glibc*.i686 glibc glibc-devel glibc-devel*.i686 ksh libgcc*.i686 libgcc libstdc++ libstdc++*.i686 libstdc++-devel libstdc++-devel*.i686 libaio libaio*.i686 libaio-devel libaio-devel*.i686 make sysstat unixODBC unixODBC*.i686 unixODBC-devel unixODBC-devel*.i686[root@web-db ~]# yum install `cat package.list` -y //安装依赖包

三.修改内核参数

[root@web-db ~]# cp /etc/sysctl.conf \ /etc/sysctl.conf_20131016.bak//备份文件 [root@web-db ~]# cat /etc/sysctl.conf //在文件爱呢最后添加如下 ##==========Setting For Oracle 11G R2============## kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 fs.file-max = 6815744 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 4194304 net.core.wmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_max = 1048576[root@web-db ~]# sysctl -p //让修改立即生效 net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key error: "net.bridge.bridge-nf-call-iptables" is an unknown key error: "net.bridge.bridge-nf-call-arptables" is an unknown key kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 fs.file-max = 6815744 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 4194304 net.core.wmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_max = 1048576

四. 创建Oracle用户以及相关权限修改

1. 创建oracle 用户组跟用户

[root@web-db ~]# groupadd oinstall [root@web-db ~]# groupadd dba [root@web-db ~]# useradd -g oinstall -G dba -m oracle [root@web-db ~]# echo oracle |passwd --stdin oracle //创建密码 Changing password for user oracle. passwd: all authentication tokens updated successfully.

2. 修改限制

[root@web-db ~]# cp /etc/security/limits.conf /etc/security/limits.conf.20131016.bak ##=============Setting For Oracle 11G R2=============## oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240 [root@web-db ~]# cat /etc/pam.d/login ##======Setting For Oracle 11G R2========## session required pam_limits.so [root@web-db ~]# cat /etc/profile ##===Setting For Oracle 11G R2=====## if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi [root@web-db ~]# source /etc/profile
