1、创建Oracle安装目录
mkdir -p /u01/oracle/
2、创建用户账号
注意：安装Oracle数据库时必须使用非root用户，root用户被禁止安装groupadd oinstall groupadd dba groupadd oper groupadd asmadmin useradd -u 500 -g oinstall -G dba,oper,asmadmin -d /u01/oracle oracle passwd oracle #设置oracle用户密码chown -R oracle:oinstall /u01 chmod -R 775 /u01
3、配置用户环境
编辑/etc/profile .bash_profile 文件export PS1="`/bin/hostname -s`-> "export ORACLE_SID=wishdb export ORACLE_BASE=/u01/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib export PATH=$ORACLE_HOME/bin:$HOME/bin:/sbin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib编辑/etc/profile文件if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi
4、配置内核参数
编辑/etc/sysctl.conf文件,添加以下内容.
kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 4194304 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 net.ipv4.ipfrag_high_thresh = 524288 net.ipv4.ipfrag_low_thresh = 393216 net.ipv4.tcp_rmem = 4096 524288 16777216 net.ipv4.tcp_wmem = 4096 524288 16777216 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_sack = 0 net.ipv4.tcp_window_scaling = 1 net.core.optmem_max = 524287 net.core.netdev_max_backlog = 2500 net.ipv4.tcp_mem = 16384 16384 16384 fs.file-max = 6815744 fs.aio-max-nr = 1048576添加以上内容后必须刷新内核参数：sysctl -p
5、配置登录认证
编辑/etc/pam.d/login文件，添加以下内容,vi /etc/pam.d/login session required /lib/security/pam_limits.so session required pam_limits.so
6、配置limits.conf文件
编辑/etc/security/limits.conf文件，添加以下内容，，vi /etc/security/limits.conf oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536
