*网站服务器
主要任务:
根据开发设计需求架设大型的网站服务器
主要软件:
apache+jboss+oracle
简称:LAJO
apache+php+mysql
简称:LAMP
proftpd+mysql
简称:LPM
ssh+expect
iptables
bind
mail
具体要求:
海量用户访问
海量用户存储
(国内外互通)
南北互通.
需求分析:
1.保证高要求高质量高性能,需要选择系*nix操作平台(这里选择as4.3);
2.保证高访问量高数据处理,需要选数商业数据库(这里选择oracle9.2.0.4);
3.解决南北互通(包括国内外互通),需要架设基于bind-view功能的智能DNS服务器.
4.使用流行的B/S,C/S程序架构,需要选择了JBOSS服务器.
5.更好地处理静态页面效果,需要选择了Apache服务器.
6.根据程序注册用户与上传要求,需要架设ftp服务器.
7.时时自动化系统监控,需要架设LAPM服务器.(这里使用软件cacti).
8.公司与客户交流,需要架设邮件服务器.(这里使用postfix+extmail).
9.自动化文件数据处理与安全设置,需expect+ssh+iptables结合shell脚本.
10.海量,需要集群负载均衡与配备存储设备.
具体流程:
1.硬件采购.
这里略.
2.操作系统安装
安装redhat as 4.3
系统空间划分(略)
安装开发环境,DNS,LAMP环境所需软件包.
并确认以下包已安装:
compat-db
compat-gcc
compat-gcc-32
compat-oracle-rhel4
compat-libcwait
compat-libgcc
compat-libstdc++-296
compat-libstdc++-33
gcc
gcc-c++
gnome-libs
gnome-libs-devel
libaio-devel
libaio
make
openmotif21
xorg-x11-deprecated-libs-devel
xorg-x11-deprecated-libs
sysstat disk4
openmotif21 disk3
libaio disk3
libaio-devel disk3
freetype-devel disk3
fontconfig-devel disk3
xorg-x11-devel- disk3
xorg-x11-deprecated-libs-devel- disk3

注意:我遇到的一个问题：全新的dell服务器1.5T,raid5,重没有安装过任何系统，硬盘也没有分区，直接用as4.3安装盘安装提示：内存错误，蓝屏，而安装失败。用了好几种linux系统盘（包括windows安装盘）都如此，（手里没有硬盘格式分区工具，没有测试是否可以硬盘分区。）官方发行版说不支持超过2G内存，于是安装系统时先卸下2G内存，待安装完毕在请求支持超过2G内存的内核安装后就可以支持4G内存了，倘如日后全新安装系统不使用hugemem而使用默认的smp内核也能识别4G内存，更不会出现蓝屏问题。关于之中奥妙，还没有仔细研究过。。。。
#rpm –ivh kernel-elhugemem….rpm
修改启动文件grub.conf确保新安装的内核为优先启动.
#cat /etc/grub.conf

////////////////////////////////////////////////////////////////////////////////////////////////
如果hiddenmenu
下面的内容顺序不对,请修改default=x(x对应ELhugemem项)
重启并加载另外2G内存.
这样让系统支持4G内存的正常运行.
2)系统安装完毕请 作连接: #ln –s /tmp /temp
3.配置DNS
由于要南北互通,开源得只有使用view的ACL访问控制列表文件来实现多线路的自动导向.
(当然也有其他的商业解决办法,比如智能路由与交换机的设置来实现,我们这里使用开源的而且容易实现与调整的解决软件bind)
关于view的ACL获得办法有很多途径,这里不一一商讨.
具体架设参考如下
默认安装的bind为9系列的,已经支持view,配置分为三步骤分别如下所示.
(1)修改named.conf
(2)创建与配置hosts
(3)域名解析

客服端测试:
nslookup --type=a xxxx.com x.x.x.x(网通任意一个DNS服务器IP)
nslookup --type=a xxxx.com x.x.x.x(电信任意一个DNS服务器IP)
看到的为配置文件中对应ip则解析配置正常.
注意:
上面的xxxxx.com需要修改DNS解析服务器为
ns.xxxxx.com
对应IP为:网通IP.
备注:
1).在这里做了网通与非网通的访问控制,用于实现南北互通,如要国内外互通,需要在列出一个相应的访问控制列表ACL就可以实现了.
2).关于使用tar包编译安装请参看:
http://www.mingfor.com/forum/showthread.php?tid=94
4.配置LAJO
软件:
Apache2.0.58
JBOSS.4.0.3SP1
Oracle9.2.0.4
Mod-jk1.12
配置:
1)apache+mod-jk
#tar zxvf httpd-2.0.58.tar.gz
#cd httpd-2.0.58
#./configure --enable-MODULE=shared --enable-so --with-mpm=worker
#make&&make install
#tar zxvf jakarta-tomcat-connectors-1.2.14.1-src.tar.gz
#cd /home/software/jakarta-tomcat-connectors-1.2.14.1-src/jk/native
# ./configure --with-apxs=/usr/local/apache2/bin/apxs
#make
# cp ./apache-2.0/mod_jk.so /usr/local/apache2/modules
httpd.conf的修改
该文件的路径位于$APACHE-HOME/conf
上述编译过程中我们选用的worker模式，因此我们将修改worker模块的配置
<IfModule worker.c>
StartServers 4 #最初建立进程的数量
ServerLimit 24 #进程建立的最大数量，硬限制
ThreadLimit 128 #每一进程能创建线程的最大数量，硬限制，该参数建议#和ThreadsPerChild一致，如果ThreadLimit > ThreadsPerChild的话，会造成不##必要的内存消耗。
MaxClients 3072 #同时可以得到处理的客户端的最大数量
MinSpareThreads 100 #所有进程中空闲线程的总数最小数值
MaxSpareThreads 200 #所有进程中空闲线程的总数最大数值
ThreadsPerChild 128 #每个子进程可以建立的固定数量的线程
MaxRequestsPerChild 0 #用于控制服务器建立和结束进程的频率,为0表示没有#限制，但在solaris OS下该值可能会出错，可以设置为1000或2000。根据系统#的并发负载吧。
</IfModule>
同时修改与新增httpd.conf如下内容：
Include conf/mod_jk2.conf
User xxxx
Group 5dxc
DocumentRoot "/site"
<Directory "/site">
NameVirtualHost IP:80
<VirtualHost IP:80>
ServerAdmin foway@163.com

3) apache+jboos服务启动问题
apache+jboss整合配置已完毕.下面是启动这些服务了.
..用户与权限分配
groupadd –g 5500 xxxx
adduser -u 5500 -s /bin/false -d /bin/null -c "proftpd user" -g xxxx xxxx
修改/etc/passwd文件中的xxxx用户中的”/bin/false”为”/bin/bash”,以便于以后jboss使用.当然你也可以这样做:
adduser -u 5500 -s /bin/bash -d /bin/null -c "proftpd user" -g xxxx xxxx
chown xxxx /site/* –R
chgrp xxxx /site/* -R
chmod 755 /site/* -R
..服务启动

4)oracle安装与启动
创建相关安装目录和环境变量
1，创建user/group；
#groupadd dba
#groupadd oinstall
#useradd oracle -g oinstall -G dba
#passwd oracle
2，建立oracle安装文件夹；
# mkdir -p /opt/ora9/product/9.2.0.4
# mkdir /var/opt/oracle
# chmod oracle.dba /var/opt/oracle
# chown -R oracle.dba /opt/ora9
3，配置环境变量；
以root用户登录，设置root用户的环境打开.bash_profile文件，将如下内容加入：
export ORACLE_BASE=/opt/ora9
export ORACLE_HOME=/opt/ora9/product/9.2.0.4
export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/Apache/Apache/bin
export ORACLE_OWNER=oracle
export ORACLE_SID=oradb //此处为你的sid
使用Oracle用户登陆:
#su – oracle
$vi .bash_profile
以下是配置文件的内容
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export ORACLE_BASE=/opt/ora9
export ORACLE_HOME=/opt/ora9/product/9.2.0.4
export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/Apache/Apache/bin
export ORACLE_OWNER=oracle
export ORACLE_SID=oradb
export ORACLE_TERM=xterm
export LD_ASSUME_KERNEL=2.4.19
export THREADS_FLAG=native
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
export NLS_LANG=”American_america.utf8”
export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data
export PATH
unset USERNAME
4，设置系统参数；
#su – root切换到root用户
a) 修改#vi /etc/sysctl.conf, 以下是配置文件的内容:
# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and
# sysctl.conf(5) for more details.
# Controls IP packet forwarding
net.ipv4.ip_forward = 0
# Controls source route verification
net.ipv4.conf.default.rp_filter = 1
# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 0
# Controls whether core dumps will append the PID to the core filename.
# Useful for debugging multi-threaded applications.
kernel.core_uses_pid = 1
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
修改后运行
#sysctl –p
命令使得内核改变立即生效；
注：
一般情况下可以设置最大共享内存为物理内存的一半，如果物理内存是 2G，则可以设置最大共享内存为 1073741824，如上；如物理内存是 1G，则可以设置最大共享内存为 512 * 1024 * 1024 = 536870912；以此类推。
建议永久地增加 shmmax 设置。
sem 4 个参数依次为SEMMSL(每个用户拥有信号量最大数)；SEMMNS(系统信号量最大数)；SEMOPM(每次semopm系统调用操作数)； SEMMNI(系统辛苦量集数最大数).Shmmax 最大共享内存，官方文档建议是内存的1/2,Shmmni 最小共享内存 4096KB.Shmall 所有内存大小 。
b) 设置oracle对文件的要求：
编辑文件：#vi /etc/security/limits.conf 加入以下语句：
oracle soft nofile 65536
oracle hard nofile 65536
oracle soft nproc 16384
oracle hard nproc 16384
也可以写成:
* soft nofile 65536
* hard nofile 65536
* soft nproc 16384
* hard nproc 16384
c) gcc降级
#mv /usr/bin/gcc /usr/bin/gcc34
#ln –s /usr/bin/gcc32 /usr/bin/gcc
#mv /usr/bin/g++ /usr/bin/g++34
#ln –s /usr/bin/g++32 /usr/bin/g++
5，安装oracle补丁
# cd /opt
#ls compat*.rpm
compat-libcwait-2.0-2.i386.rpm compat-oracle-rhel4-1.0-5.i386.rpm
# rpm -Uvh compat*.rpm
Preparing... ########################################### [100%]
1:compat-libcwait-2.0-2.i386.rpm ##################################### [ 50%]
2:compat-oracle-rhel4-1.0-5.i386.rpm#################################### [100%]
开始安装Oracle9i
1,解压下载的安装文件:
#zcat ship_9204_linux_disk1.cpio.gz | cpio –idmv&&zcat ship_9204_linux_disk2.cpio.gz | cpio –idmv&& zcat ship_9204_linux_disk3.cpio.gz | cpio –idmv
解包和解压过程中，自动创建了3个包含安装文件的目录：
Disk1
Disk2
Disk3
.以oracle用户登录系统，进行Oracle的安装(注意请不要在root登录中切换到oracle,是以oracle登录到系统(图形界面))：
$ cd Disk1
$ ./runInstaller过一会儿就会出现Oracle的安装界面
- Welcome Screen: Click Next
- Inventory Location: Click Next
- Unix Group Name: Use "oinstall" and click Next
When asked to run /tmp/orainstRoot.sh, run it before you click Continue
- At the end of the installation, exit runInstaller.
2.一步一个脚印安装下去就行了！
3,安装完后打补丁：
切换到oracle：#su – oracle 首先安装 opatch.
$cd /opt
$unzip p2617419_210_GENERIC.zip
Archive: p2617419_210_GENERIC.zip
creating: OPatch/
creating: OPatch/docs/
inflating: Opatch/docs/FAQ
......
inflating: README.txt
$export PATH=$PATH:/opt/OPatch:/sbin
(修改PATH时要要包括解压缩出来的Opatch 和 sbin目录)
$unzip p3238244_9204_LINUX.zip
$export ORACLE_BASE=/opt/ora9
$export ORACLE_HOME=/opt/ora9/product/9.2.0.4
$ cd 3238244
$opatch apply
出现success的提示就全部安装成功.
补丁打完后，还要relinked一个.mk文件
$cd $ORACLE_HOME/network/lib
$make -f ins_oemagent.mk install
之后就可以启动Agent服务了.
4, 最后执行 $dbca 建oracle数据库
注意:在SID处指定为oradb (与 ORACLE_SID=oradb)中的值一致.
点击OK，然后退出即可,正常登陆并启动数据库的操作。
$ lsnrctl start
$ sqlplus /nolog

5, oracle服务启动
以root身份进入，编写以下脚本：
vi /etc/init.d/oracle
////////////内容//////////////////
#!/bin/bash
#start and stop the oracle instance
# chkconfig –level 5 --add ora9i
#chkconfig: 345 91 19
# description: starts the oracle listener and instance
export ORACLE_HOME="/opt/ora9/product/9.2.0.4"
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/Apache/Apache/bin:$PATH
export ORACLE_OWNER="oracle"
export ORACLE_SID=oradb
if [ ! -f $ORACLE_HOME/bin/dbstart -o ! -d $ORACLE_HOME ]
then
echo "oracle startup:cannot start"
exit 1
fi
case "$1" in
start)
#startup the listener and instance
echo -n "oracle startup: "
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/lsnrctl start"
su - $ORACLE_OWNER -c $ORACLE_HOME/bin/dbstart
touch /var/lock/subsys/oracle
echo "finished"
;;
stop)
# stop listener, apache and database
echo -n "oracle shutdown:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/lsnrctl stop"
su - $ORACLE_OWNER -c $ORACLE_HOME/bin/dbshut
rm -f /var/lock/subsys/oracle
echo "finished"
;;
reload|restart)
$0 stop
$0 start
;;
*)
echo "Usage: ora9i [start|stop|reload|restart]"
exit 1
esac
exit 0
////////////内容//////////////////
给予执行权限，以root身份运行/etc/rc.d/init.d/oracle start |stop 来管理oracle的启动和停止了。如果要将这个脚本加入到系统中使其可开机运行(不过官方是不建议开机自动运行的,我本人也不建议这样做,你确实需要可以这么做)，那么要运行以下命令： chkconfig --level 35 --add oracle
或者以root用户执行如下命令:
#chmod a+x /etc/rc.d/init.d /oracle
#cd /etc/rc.d/rc5.d
#ln -s /etc/rc.d/init.d/oracle S99ora9i
#cd /etc/rc.d/rc0.d
#ln -s /etc/rc.d/init.d/oracle K99ora9i
也可如下自启动oracle9i!
在/etc/rc.d/rc.local中加入如下：
su - oracle -c "/opt/ora9/oracle/product/9.2.0.4/bin/lsnrctl start"
su - oracle -c "/opt/ora9/oracle/product/9.2.0.4/bin/dbstart start"注意:如果启动不理想,请编写shell scripts:
方法:以我个人习惯为例;;;;;;;;;;
#mkdir /usr/local/syscmf
#vi /usr/local/syscmf/oracle.sh
////////////////////////文件内容开始///////////////////
#!/bin/sh
#modify by mingfu 060404
#oracle run scripts
#run user for oracle
lsnrctl start
expect /usr/local/syscmf/oracle.exp
////////////////////////文件内容结束///////////////////
#vi /usr/local/syscmf/oracle.exp
////////////////////////文件内容开始///////////////////
#!/usr/local/bin/expect
#modify by mingfu 060404
#oracle run scripts
set timeout 120
spawn sqlplus //nolog
expect "SQL/>"
send "conn // as sysdba/r"
expect "SQL/>"
send "startup/r"
expect "SQL/>"
send "exit/r"
exit
////////////////////////文件内容结束///////////////////
#chown oracle /usr/local/syscmf/*
#chgrp oracle /usr/local/syscmf./*
#chmod 755 /usr/local/syscmf/*
在/etc/rc.local中新增如下内容:
su – oracle /usr/local/syscmf/oracle.sh
删除原来的:
su - oracle -c "/opt/ora9/oracle/product/9.2.0.4/bin/lsnrctl start"
su - oracle -c "/opt/ora9/oracle/product/9.2.0.4/bin/dbstart start"
6, 关于数据库删除重新安装的问题:
把ORACLE安装目录删除及/etc/ora*.*删除就行了
#rm –f /etc/ora*.*
7，关于在LINUX中运行管理软件$oemapp
#su – oracle
$oemapp console
8, 中文显示不正常解决办法
Oracle 目前缺省安装的字符集是WE8MSWIN1252，不是中文字符集，并且不能通过直接运行 alter database character set ZHS16GBK ; 来修改，因为ZHS16GBK不是缺省字符集的超集。过去流传很广的直接修改sys用户下的PROPS$表的方法,也会给字符集的变更留下很多潜在的问题.
linux下进行如下的操作来修改字符集：
sqlplus /nolog
sql>conn / as sysdba
sql>shutdown immediate
sql>startup mount
sql>alter system enable restricted session ;
sql>alter system set JOB_QUEUE_PROCESSES=0;
sql>alter system set AQ_TM_PROCESSES=0;
sql>alter database open ;
sql>alter database character set internal_use ZHS16GBK ;
sql>shutdown immediate
sql>startup
这样字符集的修改就完成了（如果你在安装时选择了中文字符集，这里就不用修改了）
LAJO服务环境配置完毕.
5.配置LAMP
系统自带安装http+php+mysql软件包,进行配置如下:
Apache配置
修改/etc/httpd/conf/httpd.conf内容如下:
Listen 82
ServerName 127.0.0.1:82
DocumentRoot "/var/www/html"
<Directory "/var/www/html">
注意:系统已经有两个httpd服务进程.
用户分别是:xxxx apache
请确保
/usr/local/apache2/bin/apachectl start
/etc/init.d/httpd start
此两个服务自启动.
Mysql设置
Mysql>create ftpdb;
Mysql>grant all privileges on ftpdb.* to ftpuser@localhost identified by “xxxx”;
Mysql>grant all privileges on *.* to root@’%’ identified by “xxxx”;
Mysql>flush privileges;
Mysql>exit
请确保
/etc/init.d/mysqld start
此服务自启动.
LAMP服务环境配置完毕.
7.配置FTP
配合工程实施与建立ftp帐号相关联,方便维护与管理,我这里选择了Proftpd与数据库结合的方式来实现的.
创建Ftpdb结构:
Mysql>use ftpdb;
Mysql> CREATE TABLE `ftpgroup` (
`groupname` varchar(16) NOT NULL default ’’,
`gid` smallint(6) NOT NULL default ’5500’,
`members` varchar(16) NOT NULL default ’’,

) ;
Mysql> CREATE TABLE `ftpquotalimits` (
`name` varchar(30) default NULL,

`limit_type` enum(’soft’,’hard’) NOT NULL default ’soft’,
`bytes_in_avail` float NOT NULL default ’0’,
`bytes_out_avail` float NOT NULL default ’0’,
`bytes_xfer_avail` float NOT NULL default ’0’,
`files_in_avail` int(10) unsigned NOT NULL default ’0’,

`files_in_used` int(10) unsigned NOT NULL default ’0’,
`files_out_used` int(10) unsigned NOT NULL default ’0’,
`files_xfer_used` int(10) unsigned NOT NULL default ’0’
) ;
Mysql> CREATE TABLE `ftpuser` (
`id` int(10) unsigned NOT NULL auto_increment,
`userid` varchar(32) NOT NULL default ’’,
`passwd` varchar(32) NOT NULL default ’’,
`uid` smallint(6) NOT NULL default ’5500’,
`gid` smallint(6) NOT NULL default ’5500’,
`homedir` varchar(255) NOT NULL default ’’,
`shell` varchar(16) NOT NULL default ’/sbin/nologin’,
`count` int(11) NOT NULL default ’0’,
`accessed` datetime NOT NULL default ’0000-00-00 00:00:00’,
`modified` datetime NOT NULL default ’0000-00-00 00:00:00’,
PRIMARY KEY (`id`)
) ;
Mysql> INSERT INTO `ftpgroup` (`groupname`, `gid`, `members`) VALUES("5dxc", "5500", "xxxx");
Mysql>INSERT INTO `ftpquotalimits` (`name`, `quota_type`, `per_session`, `limit_type`, `bytes_in_avail`, `bytes_out_avail`, `bytes_xfer_avail`, `files_in_avail`, `files_out_avail`, `files_xfer_avail`) VALUES("test", "user", "false", "soft", "1.024e+06", "0", "0", "0", "0", "0");
Mysql> INSERT INTO `ftpquotatallies` (`name`, `quota_type`, `bytes_in_used`, `bytes_out_used`, `bytes_xfer_used`, `files_in_used`, `files_out_used`, `files_xfer_used`) VALUES("test", "user", "809781", "0", "809781", "0", "0", "0");
Mysql> INSERT INTO `ftpuser` (`id`, `userid`, `passwd`, `uid`, `gid`, `homedir`, `shell`, `count`, `accessed`, `modified`) VALUES("1", "test", "test", "5500", "5500", "/site", "/sbin/nologin", "0", "0000-00-00 00:00:00", "0000-00-00 00:00:00");
配置proftp:
#tar xzvf proftpd-1.3.0rc5.tar.gz

////////////////////////文件内容///////////////////
在/etc/rc.local文件中新增
/usr/local/proftpd/sbin/proftpd &
LPM配置完毕.
注意:以后添加ftp帐号只需操作ftpuser表添加相应字段.用户磁盘限额操作ftpquotalimits表添加相应字段.
Mysql管理win工具推荐:mysql-front
其中远程连接帐号:
User:root
Host:IP
Pswd:xxxx
(与grant all privileges on *.* to root@’%’ identified by “xxxx”;
中设置的密码一致) .
架设也可参考如下连接:
http://www.mingfor.com/forum/showthread.php?tid=28
8.配置MAIL
配合jboss工程程序实施与建立MAIL帐号相关联,方便维护与管理,我这里选择了邮件服务器与数据库结合的方式来实现的.
具体架设参考邮件发送程序,然后来配置邮件服务器,邮件系统的用户帐号不准创建真实的系统帐号,所有的帐号均建在mysql数据库中.
具体架设过程略。
架设可参考如下连接:
http://www.mingfor.com/forum/showthread.php?tid=19
http://www.extmail.org
9.安全策略
下面是一个简易有效的防火墙设置,只要没有固定IP来入侵,服务器均可正常访问.
因此服务器上线后需要提取服务器通信状态信息.这里服务器已进配置好LAMP环境,因此系统监控请安装CACTI(http://www.cacti.net)软件来监控.
关于它的安装方法比较简单,这里不一一说明了.
还要时时将#netstat –na|grep SYN的结果中连续15个相同的伪连接给DJOP出系统通信间道.
当有这样的入侵连接时….
#iptables –A …………..djop(注意请不要将这个写入到iptables文件中)
下面是iptables文件的所有内容:
#cat /etc/sysconfig/iptables
