Oracle 12c Study之-- Oracle 12.2安装

Oracle 12c Study之-- Oracle 12.2安装 系统环境： 操作系统：  RedHat EL6（64） Oracle：     Oracle 12C（2） 一、安装环境准备 1、配置内核参数 [root@rh64 ~]# vi /etc/sysctl.conf  kernel.shmmni = 4096 # semaphores: semmsl, semmns, semopm, semmni kernel.sem = 250 32000 100 128 fs.file-max = 65536 net.ipv4.ip_local_port_range = 1024 65000 net.core.rmem_default=262144 net.core.rmem_max=4194304 net.core.wmem_default=262144 net.core.wmem_max=262144 内核参数生效： [root@rh64 ~]# sysctl -p 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 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 fs.file-max = 65536 net.ipv4.ip_local_port_range = 1024 65000 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 262144 配置用户资源限制 ： [root@rh64 ~]# vi /etc/security/limits.conf *                soft    nproc           2047 *                hard    nproc           16384 *                soft    nofile          1024 *                hard    nofile          65536  二、安装相应软件包 1、配置yum文件 [root@rh64 ~]# cd /etc/yum.repos.d/ [root@rh64 yum.repos.d]# cat yum.repo  [base] name=Red Hat Enterprise Linux baseurl=file:///media/Server enabled=1 gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release 2、软件包安装： [root@rh64 yum.repos.d]# rpm -qa compat-libstdc++-33 elfutils-libelf-devel glibc-devel-2.5 gcc gcc-4.4.7-3.el6.x86_64 elfutils-libelf-devel-0.152-1.el6.x86_64 [root@rh64 yum.repos.d]# yum install -y compat*  [root@rh64 yum.repos.d]# yum install -y glibc* [root@rh64 yum.repos.d]#  rpm -qa libaio-devel libstdcc++-devel unixODBC unixODBC-devel sysstat binutils sysstat-9.0.4-20.el6.x86_64 binutils-2.20.51.0.2-5.36.el6.x86_64 [root@rh64 yum.repos.d]# yum install -y libaio* [root@rh64 yum.repos.d]# yum install -y libst* [root@rh64 yum.repos.d]# yum install -y unix* [root@rh64 yum.repos.d]# rpm -q elfutils-libelf glibc-common libaio libgcc libstdc++ make 三、配置用户环境 [oracle@rh64 ~]$ cat .bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then         . ~/.bashrc fi # User specific environment and startup programs #oracle Settings export TMP=/tmp export TMPDIR=$TMP export LC_ALL=en_US.UTF-8 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/12.2.0/db_1   export PATH=$ORACLE_HOME/bin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH export CLASSPATH=$ORACLE_HOME/JREORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi 四、建立相关目录 [root@rh64 yum.repos.d]# mkdir -p /u01/app/oracle [root@rh64 yum.repos.d]# id oracle uid=200(oracle) gid=200(oinstall) groups=200(oinstall),201(dba) [root@rh64 yum.repos.d]# chown -R oracle:oinstall /u01 五、Oracle软件安装 Oracle 12c软件安装和Oracle 11g安装基本区别不大 六、创建数据库 对于Oracle 12c增加了多租户数据库的创建！
