-----------------------------------
一、前言
OpenBSD是一个多平台的，基于4.4BSD的类UNIX操作系统，是BSD衍生出的三种免费操作系统（另外两种是NetBSD和FreeBSD）之一，被称为世界上最安全的操作系统。专案领导人 Theo de Raadt在1995年发起了OpenBSD 专案，希望创造一个注重安全的操作系统。
二、环境
系统：openBSD5.5
官方网站 http://www.openbsd.org/
镜像源(找不到中国的镜像站点，随便选了一个)
安装系统基本是傻瓜式的（系统可以在镜像站点下载，找到install55.iso即可），只要能稍微看懂英语的，都可以解决的，在此，不再描述具体安装过程。安装完毕后一定要重启才能使用系统。
三、配置网络及镜像源
1.配置网络，在虚拟机中安装，网络适配器选择桥接，我用TP-link的路由器使用dhcp分配地址。
如果没有自动获得IP地址，可以使用dhclient vic0获得。
# dhclient vic0 DHCPREQUEST on vic0 to 255.255.255.255 port 67 DHCPACK from 192.168.1.1 (b0:48:7a:1f:a5:80) bound to 192.168.1.101 -- renewal in 3600 seconds. # ping www.baidu.com PING www.a.shifen.com (61.135.169.125): 56 data bytes 64 bytes from 61.135.169.125: icmp_seq=0 ttl=55 time=23.993 ms 64 bytes from 61.135.169.125: icmp_seq=1 ttl=55 time=19.759 ms --- www.a.shifen.com ping statistics --- 2 packets transmitted, 2 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 19.759/21.876/23.993/2.117 ms
2.配置镜像源
# vi /root/.profile export PKG_PATH=ftp://mirrors.nycbug.org/pub/OpenBSD/5.5/packages/i386/ //重启(没有source命令）
四、packages安装(和yum非常相似)
# echo $SHELL //默认ksh /bin/ksh # pkg_add -v bash //测试安装bash，大概有8471个软件包可以使用。 quirks-1.113: ok bash-4.2.45p0:libiconv-1.14p1: ok bash-4.2.45p0:gettext-0.18.2p4: ok Shell /usr/local/bin/bash appended to /etc/shells bash-4.2.45p0: ok # pkg_info bash-4.2.45p0 GNU Bourne Again Shell gettext-0.18.2p4 GNU gettext libiconv-1.14p1 character set conversion library quirks-1.113 exceptions to pkg_add rules
五、添加用户
# adduser
Use option ``-silent‘‘ if you don‘t want to see all warnings and questions.
Reading /etc/shells
Check /etc/master.passwd
Check /etc/group
Ok, let‘s go.
Don‘t worry about mistakes. There will be a chance later to correct any input.
Enter username []: nuo
Enter full name []: Nuo Wei
Enter shell csh ksh nologin sh [ksh]:
Uid [1000]:
Login group nuo [nuo]:
Login group is ``nuo‘‘. Invite nuo into other groups: guest no
[no]:
Login class authpf bgpd daemon default staff [default]:
Enter password []:
Enter password again []:
Name: nuo
Password: ****
Fullname: Nuo Wei
Uid: 1000
Gid: 1000 (nuo)
Groups: nuo
Login Class: default
HOME: /home/nuo
Shell: /bin/ksh
OK? (y/n) [y]:
Added user ``nuo‘‘
Copy files from /etc/skel to /home/nuo
Add another user? (y/n) [y]: n
Goodbye!
# ls -l /home

drwxr-xr-x 3 nuo nuo 512 May 10 19:36 nuo
# su - nuo //切换用户，并改变shell
$ chsh -s bash

-bash-4.2$ su - //切换到root用户
Password:
you are not in group wheel //默认是无法切换的，因为nuo用户不在wheel组中。
Sorry
-bash-4.2$ cat /etc/group |grep wheel
wheel:*:0:root
# usermod -G wheel nuo //在root用户下将nuo用户添加到wheel组中。
# cat /etc/group |grep wheel
wheel:*:0:root,nuo
# su - nuo //再次切换，成功！
-bash-4.2$ su -
Password:
# who am i
root ttyp1 May 10 19:51 (192.168.1.100)
# vi /etc/ssh/sshd_config
42 #PermitRootLogin yes //默认root是可以远程的。但是这样是不安全的。
所以创建一个普通用户，首先以一个普通用户登录，如果需要root权限，su到root用户。
42 PermitRootLogin no //更改默认选项
# /etc/rc.d/sshd restart //重启ssh
sshd(ok)
sshd(ok)六、ports安装（即源码安装,编译安装apache为例）
# cd /tmp/
# ftp ftp://mirrors.nycbug.org/pub/OpenBSD/5.5/ports.tar.gz //下载ports
# ls
.ICE-unix .X11-unix aucat ports.tar.gz
# cd /usr/
# tar -zxvf /tmp/ports.tar.gz //时间挺长的，耐心等待。
# which httpd
/usr/sbin/httpd
# /usr/sbin/httpd -v
Server version: Apache/1.3.29 (Unix) //版本太老了，可能由于许可问题，一直未更新。
# pwd
/usr
# ls
X11R6 games lib libexec local obj sbin src
bin include libdata lkm mdec ports share xobj
# cd /usr/ports/
# ls //安装httpd在www目录下编译安装，安装mysql在databases目录下编译安装...

# cd www/
# cd apache-httpd/
# ls
CVS Makefile distinfo patches pkg
# pwd
/usr/ports/www/apache-httpd
# make install //安装其它源码也这样，进入到相对应的目录，make install即可
编译安装近两个小时，主要是下载太慢，可能是由于国外镜像站点原因吧。
apache-httpd-2.2.26: ok //最新版本
The following new rcscripts were installed: /etc/rc.d/httpd2
See rc.d(8) for details.
--- +apache-httpd-2.2.26 -------------------
This is the official httpd distributed by the Apache Server Project,
provided as a port for those who, for various reasons, need to run
version 2.
OpenBSD provides a custom Apache server, httpd(8), in the base system
which has been audited for security and may run in a chroot(2)
environment. Users are STRONGLY encouraged to use the system httpd
rather than this port.
