2018-1-3 第一节 安装系统redhat (redhat6.9) for oracle

redhat6.9  系统推送代码 for oracle

第一步:分区

# CLASSROOM MACHINE(c) NEED A DISK OF: 90000M  
cat >>  /tmp/partitioning <

第二步:系统配置

1、关闭防火墙：

查看防火墙状：

[root@station10 ~]# chkconfig --list iptables
iptables        0:off   1:off   2:on    3:on    4:on    5:on    6:off

立即关闭，并非永久关闭

[root@station10 ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]

永久关闭

[root@station10 ~]# chkconfig iptables off

2、配置网络:

[root@station10 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0 

DEVICE=eth0  
BOOTPROTO=none  
ONBOOT=yes  
NETMASK=255.255.255.0  
IPADDR=XXX  
GATEWAY=192.168.0.254  
TYPE=Ethernet  
USERCTL=no  
IPV6INIT=no  
PEERDNS=yes 

3、挂载ISO文件

给ISO文件建立一个挂载点

[root@station10 /]# mkdir cd

[root@station10 /]#mount -o loop /stage/rhel-server-6.9-x86_64-dvd.iso  /cd

4、  配置yum源

配置本地文件源:

vim /etc/yum.repos.d/base.repo

配置163源:

在cd /etc/yum.repos.d下新建一个163.repo文件

root@station10 yum.repos.d]# vim /etc/yum.repos.d/163.repo

[root@localhost ~]# cd /etc/yum.repos.d/
[163]
name=163
baseurl=http://mirrors.163.com/centos/6.9/os/x86_64/
gpgcheck=0
enabled=1

这里要注意的是，baseurl这一项，你要到http://mirrors.163.com/centos这里，去找到你对应的redhat版本的目录，然后点os、再点x86_64（一般都有）,然后用你地址栏上显示的网址替换上面的baseurl就行了，保存退出。

配置epel源

rpm -vih http://dl.fedoraproject.org/pub/epel/6/x86_64/Packages/e/epel-release-6-8.noarch.rpm  

5、补包:

#显示所有已经安装和可以安装的程序包

[root@station10 yum.repos.d]# yum list | grep oracleasm

# Install the pub keys  
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-* 2>/dev/null  
 
yum -y groupinstall "Development tools"  
yum -y install libaio  
yum -y install libaio-devel  
    
yum -y install unixODBC  
yum -y install unixODBC-devel  

yum -y install oracleasm\*  
  
yum -y install openmotif\*  
yum -y install ksh\*  
yum -y install sysstat\*  
yum -y install compat\*  
yum -y install nfs-utils  
yum -y install "glibc-devel.i386"  

[root@station10 selinux]# yum -y install tigervnc-server.x86_64

[root@station10 selinux]# yum -y install tigervnc.x86_64

6、关闭:NetworkManager

chkconfig NetworkManager off  

7、关闭,SELINUX

sed -i.bak 's/SELINUX=enforcing/SELINUX=disabled/' /etc/sysconfig/selinux

[root@station10 selinux]# vim /etc/selinux/config 

selinux状态可以通过以下命令查看：
sestatus

getenforce      <<-查看selinux当前状态

8、建oracle用户/组

echo "oracle" | passwd --stdin root  
# oracle  
groupadd oinstall  
groupadd dba  
groupadd oper  
# grid  
groupadd asmadmin  
groupadd asmdba  
groupadd asmoper  
# oracle  
useradd -g oinstall -G dba,oper,asmadmin,asmdba,asmoper -d /home/oracle   oracle  
echo "oracle" | passwd --stdin oracle  
echo "export ORACLE_BASE=/u01/app/oracle" >> /home/oracle/.bash_profile  
echo '# export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1' >> /home/oracle/.bash_profile  
echo "# export ORACLE_SID=orcl"  >> /home/oracle/.bash_profile  
echo '# export TNS_ADMIN=/u01/app/oracle/product/11.2.0/grid/network/admin'  >> /home/oracle/.bash_profile  
echo "export NLS_LANG=american_america.AL32UTF8" >> /home/oracle/.bash_profile  
echo "export ORACLE_TERM=xterm" >> /home/oracle/.bash_profile  
echo "export EDITOR=vi" >> /home/oracle/.bash_profile  
echo '# export PATH=$ORACLE_HOME/bin:$PATH:/u01/app/oracle/product/11.2.0/grid/bin' >> /home/oracle/.bash_profile  
echo "export LANG=en_US" >> /home/oracle/.bash_profile  
  
mkdir -p /u01/app/oracle  
chown oracle:oinstall /u01/app  
chown oracle:oinstall /u01/app/oracle  

9、系统参数调整:

# Oracle2  
echo "fs.file-max = 6815744" >> /etc/sysctl.conf  
echo "kernel.sem = 250 32000 100 128" >> /etc/sysctl.conf  
echo "kernel.shmall = 2097152" >> /etc/sysctl.conf  
echo "kernel.shmmni = 4096" >> /etc/sysctl.conf  
echo "net.core.rmem_default=4194304" >> /etc/sysctl.conf  
echo "net.core.rmem_max=4194304" >> /etc/sysctl.conf  
echo "net.core.wmem_default=1048576" >> /etc/sysctl.conf  
echo "net.core.wmem_max=1048576" >> /etc/sysctl.conf  
echo "net.ipv4.ip_local_port_range = 9000 65500" >> /etc/sysctl.conf  
echo "fs.aio-max-nr = 1048576" >> /etc/sysctl.conf

kernel.shmmax = 68719476736

这个参数为物理内存的一半，最好是一半到三分之二中间。

# Oracle3  
echo "session required /lib/security/pam_limits.so" >>/etc/pam.d/login  
# Oracle4  
echo "grid soft nproc 2047" >>/etc/security/limits.conf  
echo "grid hard nproc 16384" >>/etc/security/limits.conf  
echo "grid soft nofile 1024" >>/etc/security/limits.conf  
echo "grid hard nofile 65536" >>/etc/security/limits.conf  
echo "oracle soft nproc 2047" >>/etc/security/limits.conf  
echo "oracle hard nproc 16384" >>/etc/security/limits.conf  
echo "oracle soft nofile 1024" >>/etc/security/limits.conf  
echo "oracle hard nofile 65536" >>/etc/security/limits.conf  

wget -P /stage/ -c --tries=1000 --wait=5 ftp://192.168.0.254/pub/O11g_x8664/DATABASES/flashplayer-11.2.202.297-1.ram0.98.x86_64.rpm  
rpm -ivh /stage/flashplayer-11.2.202.297-1.ram0.98.x86_64.rpm

# UEK3 for ASMFD 

kmod-oracleasm 6.9要装新版本的，kmod-oracleasmXXXXX6.9XXXXX

ASM盘组

chkconfig oracleasm on  
oracleasm configure -i<
