一.安装环境:
OS:Linux x86 CentOS 6.0
DB:Oracle11g R1
NETWORK:LAN
二.具体安装步骤
1、检查必备的包
使用rpm –q 来查看下列包是否已经安装，以及版本是否符合。
binutils-2.17.50.0.6-2.el5
compat-libstdc++-33-3.2.3-61
elfutils-libelf-0.125-3.el5
elfutils-libelf-devel-0.125
gcc-4.1.1-52
gcc-c++-4.1.1-52
glibc-2.5-12
glibc-common-2.5-12
glibc-devel-2.5-12
glibc-headers-2.5-12
libaio-0.3.106
libaio-devel-0.3.106
libgcc-4.1.1-52
libstdc++-4.1.1
libstdc++-devel-4.1.1-52.e15
make-3.81-1.1
numactl-devel-0.9.8.i386
sysstat-7.0.0
unixODBC-2.2.11
unixODBC-devel-2.2.11
2、添加组和用户，并创建安装目录
groupadd oinstall
groupadd dba
useradd –g oinstall –G dba oracle
passwd oracle
mkdir -p /u01/app/oracle
chown –R oracle:oinstall /u01/
3、编辑内核参数
vi /etc/sysctl.conf
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 = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
shmmax 最大共享内存，，如果机子有2G内存的话可以设置为2147483648。
执行下面命令使内核参数生效：
/sbin/sysctl –p
4、设置oracle用户的shell limit
vi /etc/security/limits.conf
添加以下内容
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
5、编辑登陆配置文件
vi /etc/pam.d/login
添加下面的语句
session required pam_limits.so或者是
session required /lib/security/pam_limits.so
6、配置IP地址
vi /etc/sysconfig/network-scripts/ifcfg-eth0
内容如下：
DEVICE=”eth0”
NM_CONTROLLED=”yes”
ONBOOT=”yes”
TYPE=Ethernet
BOOTPROTO=static
IPADDR=192.168.1.12
NETWORK=255.255.255.0
GATEWAY=192.168.1.1
PREFIX=24
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME=”System eth0”
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
HWADDR=00:0C:29:F8:C7:79:
7、修改/etc/hosts文件
vi /etc/hosts
添加如下格式的内容
127.0.0.1 hostname localhost
其中hostname可以通过hostname命令查询获得
8、设置环境变量
编辑oracle主目录下的.bash_profile
添加以下内容：
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1
export ORACLE_SID=orcl
export PATH=$PATH:$ORACLE_HOME/bin
9、执行安装
执行安装要使用oracle用户，不是su – oracle，而是在登录页面使用oracle用户登录
如果遇到乱码可以使用LANG=us_EN.utf-8临时改变系统字符环境。

Can mysql and mariadb coexist
Apr 08, 2025 pm 02:27 PM
MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
