Red Hat Linux下安装Oracle 10g中先决条件检测中遇到的问题:警告:内存的交换空间不够,有提示需要到少m,已经有多少m。需求待验
在Red Hat Linux下安装Oracle 10g中先决条件检测中遇到的问题是:
1.警告:内存的交换空间不够,有提示需要到少m,已经有多少m。
参照以下办法:(增加交换分区)
1)增加2G的交换分区
[root@localhost ~]#mkdir /root/swap
2)添加交换文件并设置其大小为2G,使用如下命令
[root@localhost ~]# dd if=/dev/zero of=/root/swap/swap bs=1024 count=2048000
读入了 2048000+0 个块
输出了 2048000+0 个块
3)创建(设置)交换空间,使用命令mkswap
[root@localhost ~]# mkswap /root/swap/swap
Setting up swapspace version 1, size = 2097147 kB
4)检查现有的交换空间大小,使用命令free
[root@localhost ~]# free -m
或者
[root@localhost ~]#grep SwapTotal /proc/meminfo
5)启动新增加的2G的交换空间,使用命令swapon
[root@localhost ~]#swapon /root/swap/swap
6)确认新增加的2G交换空间已经生效,使用命令free
[root@localhost ~]# free -m
7)修改/etc/fstab文件,,使得新加的2G交换空间在系统重新启动后自动生效
在文件最后加入:
/root/swap/swap swap swap defaults 0 0
2.需求待验证,提示如下:
正在检查网络配置需求...
检查完成。此次检查的总体结果为: 未执行 建议方案: Oracle 支持在具有 DHCP 分配的公共 IP 地址的系统上进行安装。但应使用静态 IP 地址来配置系统的主网络接口, 以便 Oracle 软件正常工作。有关在配置有 DHCP 的系统上安装软件的详细信息, 请参阅 Installation Guide。
解决办法:
1)手动设置静态IP地址(其实就是把DHCP服务器分配给你的IP地址在这里写一下)
2)编辑hosts文件(没错Linux下同样也有hosts文件,跟Windows下hosts文件的作用一样,谁模仿的谁不太清楚)
# vi /etc/hosts hosts文件里通常情况下已经有了一行(hosts文件内格式:IP 主机名 别名):
“127.0.0.1
localhost.localdomain
localhost”
将其改成:60.176.38.13 localhost.localdomain localhost
其中的60.176.38.13是你的ip,可以通过
(DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=60.176.38.13
NETMASK=255.0.0.0
GATEWAY=60.255.255.254)
然后依次按:esc——shift+:——w——q——回车这个修改是即时生效的,这时再重新安装Oracle试一下,应该就不会再报DHCP的问题了。
Linux下查看机器的主机名命令:
# hostname
之后重新测试就功德圆满了~~~

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
