本篇文章給大家分享的是有關(guān)Centos6.5 + Oracle 11g r2 + nfs如何搭建RAC環(huán)境,小編覺得挺實用的,因此分享給大家學(xué)習(xí),希望大家閱讀完這篇文章后可以有所收獲,話不多說,跟著小編一起來看看吧。
環(huán)境要求:
1.2臺系統(tǒng)為Centos6.5的機(jī)器,其中 1臺做nfs(硬盤大小至少4T)
2. 每臺機(jī)器至少2塊網(wǎng)卡
3. 準(zhǔn)備5個可用的IP地址(一個為scan,二臺配置各配置public和private地址)
4. 內(nèi)存至少2G以下內(nèi)存,建議使用4G或者更高
地址規(guī)劃:
第一臺主機(jī):rac1 網(wǎng)卡eth0 IP地址:172.16.0.1/24 網(wǎng)卡eth2地址: 192.168.1.192/24
第一臺主機(jī):rac1 網(wǎng)卡eth0 IP地址:172.16.0.2/24 網(wǎng)卡eth2: 192.168.1.193/24
虛擬IP地址:192.168.1.200
關(guān)閉ntp 并配置yum的本地源
關(guān)閉服務(wù) #/etc/init.d/ntpd stop #chkconfig ntpd off #mv /etc/ntp.conf /etc/ntp.conf.org #mkdir /mnt/cdrom/ #mount /dev/cdrom /mnt/cdrom/ #vim /etc/yum.repos.d/CentOS-Media.repo name=CentOS-$releasever - Media baseurl=file:///mnt/cdrom/ gpgcheck=0 enabled=1
安裝依賴軟件包
#yum -y install binutils-2*.rpm \ compat-libstdc++-33*.rpm \ elfutils-libelf-0.*.rpm \ elfutils-libelf-devel-*.rpm \ gcc-4*.rpm \ gcc-c++-4*.rpm \ glibc-2.*.rpm \ glibc-common-2*.rpm \ glibc-devel-2*.rpm \ libaio-0*.rpmlibgcc-4*.rpm \ libstdc++-4*.rpm \ libstdc++-devel*.rpm \ make-3*.rpm \ pdksh-*.rpm \ sysstat-7*.rpm \ libaio-devel-*.rpm \ unixODBC-2*.rpm \ unixODBC-devel-2*.rpm \
配置host文件
#vim /etc/hosts #Public 172.16.0.1 rac1-priv 172.16.0.2 rac2-priv #Virtual 192.168.1.194 rac1-vip 192.168.1.195 rac2-vip #Scan 192.168.1.200 rac-scan #NAS 192.168.1.194 nas1
修改內(nèi)核參數(shù)
#vim /etc/sysctl.conf 在最后面添加 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 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 #sysctl -p
修改文件描述符的限制
#vi /etc/security/limits.conf oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 grid soft nproc 2047 grid hard nproc 16384 grid soft nofile 1024 grid hard nofile 65536
添加pam_limits.so 模塊
vim /etc/pam.d/login 在最后添加 session required pam_limits.so
添加profile環(huán)境配置文件
#vim /etc/profile 在最后添加 if [ $USER = "oracle" ] || [$USER = "grid" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi umask 022 fi
創(chuàng)建用戶和組并創(chuàng)建相應(yīng)的密碼
#/usr/sbin/groupadd -g 501 oinstall #/usr/sbin/groupadd -g 502 dba #/usr/sbin/groupadd -g 503 oper #/usr/sbin/groupadd -g 504 asmadmin #/usr/sbin/groupadd -g 505 asmoper #/usr/sbin/groupadd -g 506 asmdba #/usr/sbin/useradd -g oinstall -Gdba,asmdba,oper oracle #/usr/sbin/useradd -g oinstall -Gasmadmin,asmdba,asmoper,oper,dba grid #passwd oracle #passwd grid
創(chuàng)建目錄并設(shè)置相應(yīng)權(quán)限
#mkdir -p /u01/app/oracle #chown -R oracle:oinstall /u01/app/oracle #chmod -R 775 /u01/app/oracle #mkdir -p /u01/app/oracle/product/11.2.0/db_1 #chown -R oracle:oinstall/u01/app/oracle/product/11.2.0/db_1 #chmod -R 775/u01/app/oracle/product/11.2.0/db_1 #mkdir -p /u01/app/grid #chown -R grid.oinstall /u01/app/grid #chmod -R 775 /u01/app/grid #mkdir -p /u01/app/11.2.0/grid #chown -R grid:oinstall /u01/app/11.2.0/grid #chmod -R 775 /u01/app/11.2.0/grid #mkdir -p /u01/app/oraInventory #chown -R grid:oinstall/u01/app/oraInventory #chmod -R 775 /u01/app/oraInventory #mkdir -p /u01/oradata #mkdir -p /u01/shared_config #chown -R oracle:oinstall /u01/oradata #chown -R grid:oinstall /u01/ shared_config #chmod -R 775 /u01/oradata/u01/shared_config
修改grid用戶環(huán)境變量
#su - grid $ vim /home/zkyg/.bash_profile alias df='df -h' alias du='du -sh' alias la='ls -lha' ORACLE_SID=NFS1; export ORACLE_SID JAVA_HOME=/usr/local/java; export JAVA_HOME ORACLE_BASE=/u01/app/grid; exportORACLE_BASE ORACLE_HOME=/u01/app/11.2.0/grid; exportORACLE_HOME ORACLE_PATH=/u01/app/oracle/common/oracle/sql;export ORACLE_PATH ORACLE_TERM=xterm; export ORACLE_TERM NLS_DATE_FORMAT="DD-MON-YYYYHH24:MI:SS"; export NLS_DATE_FORMAT TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMIN ORA_NLS11=$ORACLE_HOME/nls/data; exportORA_NLS11 PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin PATH=${PATH}:/u01/app/common/oracle/bin export PATH LD_LIBRARY_PATH=$ORACLE_HOME/lib LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib export LD_LIBRARY_PATH CLASSPATH=$ORACLE_HOME/JRE CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib export CLASSPATH THREADS_FLAG=native; export THREADS_FLAG export TEMP=/tmp export TMPDIR=/tmp umask 022
修改oracle用戶環(huán)境變量
alias df='df -h' alias du='du -sh' alias la='ls -lha' ORACLE_SID=racdb1; export ORACLE_SID ORACLE_UNQNAME=racdb; export ORACLE_UNQNAME JAVA_HOME=/usr/local/java; export JAVA_HOME ORACLE_BASE=/u01/app/oracle; exportORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1;export ORACLE_HOME ORACLE_PATH=/u01/app/common/oracle/sql;export ORACLE_PATH ORACLE_TERM=xterm; export ORACLE_TERM NLS_DATE_FORMAT="DD-MON-YYYYHH24:MI:SS"; export NLS_DATE_FORMAT TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMIN ORA_NLS11=$ORACLE_HOME/nls/data; exportORA_NLS11 PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin PATH=${PATH}:/u01/app/common/oracle/bin export PATH LD_LIBRARY_PATH=$ORACLE_HOME/lib LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib export LD_LIBRARY_PATH CLASSPATH=$ORACLE_HOME/JRE CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib export CLASSPATH THREADS_FLAG=native; export THREADS_FLAG export TEMP=/tmp export TMPDIR=/tmp umask 022
配置ssh雙機(jī)信任(gird,oracle用戶下都要配置)以oracle為例子
$ ssh-keygen -t rsa $ ssh-keygen -t dsa $ ssh-keygen -t rsa $ ssh-keygen -t dsa $ cat .ssh/id_rsa.pub >> .ssh/authorized_keys $ cat .ssh/id_dsa.pub >>.ssh/authorized_keys $ ssh rac2 cat .ssh/id_rsa.pub >>.ssh/authorized_keys $ ssh rac2 cat .ssh/id_dsa.pub >>.ssh/authorized_keys $ scp.ssh/authorized_keys rac2:.ssh/authorized_keys
在二臺機(jī)器測試是否正常
$ssh rac1 date $ssh rac2 date
以上操作需要在二臺機(jī)器都要操作
配置nfs
Rac1上使用fdisk /dev/sdb 分2個區(qū)sdb1、sdb2并進(jìn)行格式化 #mkfs.ext3 /dev/sdb1 #mkfs.ext3 /dev/sdb2 rac1上創(chuàng)建共享目錄 #mkdir -p /shared_config #mkdir -p /shared_data #vi /etc/fstab 添加以下: /dev/sdb1 /shared_config ext3 defaults 0 0 /dev/sdb2 /shared_data ext3 defaults 0 0 #vi /etc/exports 設(shè)置共享 /shared_config *(rw,sync,no_wdelay,insecure_locks,no_root_squash) /shared_data *(rw,sync,no_wdelay,insecure_locks,no_root_squash) #chkconfig nfs on開啟nfs服務(wù) #service nfs restart #vi /etc/fstab添加以下開機(jī)掛載共享目錄 nas1:/shared_config /u01/shared_config nfs rw,bg,hard,nointr,noac,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0 nas1:/shared_data /u01/oradata nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0 掛載相應(yīng)的目錄 #mount /u01/shared_config #mount /u01/oradata #chown grid:oinstall /u01/shared_config #chown oracle:oinstall /u01/oradata #chmod 775 /u01/oradata #chmod 775 /u01/app/11.2.0/grid
安裝grid軟件
unzip grid-XXX.zip 在root下輸入xhost + #su – grid $cd grid-XXX $./runcluvfy.sh stage-pre crsinst -n rac1,rac2 -fixup -verbose | tee check_grid.txt 如果最后提示:集群服務(wù)設(shè)置的預(yù)檢查成功.可以開始去安裝 grid 否則請查看失敗在什么地方解決后再次執(zhí)行該命令行來檢查. 運(yùn)行安裝目錄下的runInstaller $./ runInstaller
