### 注意事项 - swap分区需要16GB以上 - 需要配置hosts文件 - Centos 6.8 x86_64 #### YUM源配置 ```shell #clean OS default repo mkdir /etc/yum.repos.d/old && mv /etc/yum.repos.d/C* /etc/yum.repos.d/old/ yum clean all #add extend repo wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo ``` #### 创建组并指定用户所属组 ```shell groupadd oinstall groupadd dba useradd -g oinstall -G dba oracle ``` #### 创建目录 ```shell mkdir -p /app/oracle12c ``` #### 修改数据库权限 ```shell chown -R oracle.oinstall /app/ ``` #### 内核参数初始化 在/etc/sysctl.conf末尾增加以下内容 ```shell fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 4195045376 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 = 1048586 ``` #### 文件描述符修改 在/etc/security/limits.conf末尾增加 ```shell oracle soft nofile 65536 oracle hard nofile 65536 oracle soft nproc 16384 oracle hard nproc 16384 ``` #### 切换oracle用户,配置环境变量 ```shell su - oracle vim ~/.bash_profile ``` 文件末尾追加,注意修改实例名称和位置 ```shell TMP=/tmp; export TMP TMPDIR=$TMP; export TMPDIR ORACLE_BASE=/app/oracle12c; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1; export ORACLE_HOME ORACLE_SID=dingdb; export ORACLE_SID NLS_LANG=American_America.zhs16gbk; export NLS_LANG ORA_NLS10=$ORACLE_HOME/nls/data; export ORA_NLS10 TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN ORACLE_TERM=xterm; export ORACLE_TERM PATH=/usr/sbin:$PATH; export PATH PATH=$ORACLE_HOME/bin:$PATH; export PATH LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH SHLIB_PATH=$LD_LIBRARY_PATH; export SHLIB_PATH CLASSPATH=$ORACLE_HOME/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH ``` #### 增加hosts ```shell echo "192.168.2.20 odb01.prod.ding" >> /etc/hosts ``` #### 上传程序文件,并解压 ```shell cd /opt unzip linuxamd64_12102_database_1of2.zip unzip linuxamd64_12102_database_2of2.zip cd /opt/database ``` #### 安装必要软件 ```shell yum install binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libgcc libstdc++ libstdc++-devel libaio libXext libX11 libXau libxcb libXi make sysstat libaio-devel -y ``` #### 切换到图形界面 root用户执行,或sudo执行 ```shell xhost + ``` #### netca 选择"Listen Configuration"然后一直下一步 完成后查看 1521端口是否启动 #### dbca > 数据库字符集(database character set): American_America.ZHS16GBK; **第9步时,自定义字符集。 我们开发一般选择:ZHS16GBK ** ### 启动Oracle EM(Web管理) ``` su - oracle /app/oracle11g/product/11.2.0/dbhome_1/bin/emctl start dbconsole ``` ### 注意!!! ### 关闭deferred_segment_creation特性,否则空表无法导出 ```sql alter system set deferred_segment_creation=false ``` #### 监听的启动和停止 ```shell su - oracle 启动 /app/oracle12c/product/12.1.0/db_1/bin/lsnrctl start 停止 /app/oracle12c/product/12.1.0/db_1/bin/lsnrctl stop ``` #### 数据库的启动和停止 ```shell 命令行登录 sqlplus / as sysdba 启动 startup 停止 shutdown immediate ```
