遗留问题，目前不能在chroot环境里用femail外发论坛email地址验证邮件，欢迎有经验的朋友请跟贴指教，有关postgresql的优化，请参阅none兄的帖子，http://www.gobsd.org/showthread.php?t=3198&page=2 , 他的实际应用经验是“大大的”，:), 希望可以对我们这些初学者不吝赐教。:D
（受none兄煽动，实际上跑论坛程序，数据库也不会太大，体会不出postgresql稳定和高性能的优势，我在自己的Intel(R) Pentium(R) 4 CPU 1300MHz , 1.2 G内存的老机器上跑了一个几十万个帖子的phpbb论坛，居然还凑合能运行。）
设置packages的“路径”：
代码: 全选
# export PKG_PATH=ftp://gobsd.org/pub/OpenBSD/snapshots/packages/i386/代码: 全选
# pkg_add postgresql-server postgresql-client postgresql-docs
postgresql-server-9.1.3:postgresql-client-9.1.3: ok
useradd: Warning: home directory `/var/postgresql' doesn't exist, and -m was not specified
postgresql-server-9.1.3: ok
postgresql-docs-9.1.3: ok
The following new rcscripts were installed: /etc/rc.d/postgresql
See rc.d(8) for details.
Look in /usr/local/share/doc/pkg-readmes for extra documentation.代码: 全选
# su - _postgresql
$ mkdir /var/postgresql/data
$ initdb -D /var/postgresql/data -U postgres -E UTF8 -A md5 -W
The files belonging to this database system will be owned by user "_postgresql".
This user must also own the server process.
The database cluster will be initialized with locale C.
The default text search configuration will be set to "english".

or
pg_ctl -D /var/postgresql/data -l logfile start

我的修改是：在/etc/sysctl.conf里加上下列三句：

--- +femail-chroot-0.98p0 -------------------
By default, femail will use `localhost' for smtphost. Make sure to
review FAQ Section 10.16 discussing name resolution with httpd(8)'s
default chroot(2).
Additionally, one may create a custom femail.conf; see femail(8).
If you're using femail with PHP inside a chroot jail, be aware that
PHP's built-in "mail" function uses popen(), which requires /bin/sh.

修改apache配置文件以支持PHP语法。（参以前的教程）
修改 /var/www/conf/httpd.conf 文件中的下列内容：
将原内容：

DirectoryIndex index.html代码: 全选
DirectoryIndex index.php如果两个文件全需要，则修改为：
代码: 全选
DirectoryIndex index.php index.html代码: 全选
httpd_flags=""我们这里用一个常见的应用——phpbb3来测试一下postgresql数据库,将下载好的文件解压后放到OpenBSD的默认的web服务器根目录 /var/www/htdocs 里：
先重新建立一个初始化数据库：
代码: 全选
# su - _postgresql代码: 全选
$ psql -d template1 postgres
Password for user postgres:
psql (9.1.3)
Type "help" for help.
template1=# create database phpbb3;
template1-# create role leo with superuser login password 'gobsd.org';
template1-# \q
$ exit
#
代码: 全选
chmod 777 /var/www/htdocs/{cache,files,store,config.php,images/avatars/upload}
其余的web服务器设置请看以前的讨论，这里略了，我实际操作时没有问题，就是在域名设置时要有些注意的地方。
如果您有问题请跟贴讨论。
php邮件功能设置探讨：（目前没有解决的问题）
安装php时，自动安装了femail,这个package可以工作在chrooted环境下，但是我们还需要配置一下，其配置文件为 /etc/femail.conf
我的内容：
代码: 全选
# cat /etc/femail.conf
smtphost = localhost
myname = www.gobsd.org将
代码: 全选
; sendmail_path ="/var/www/bin/femail -t -i"代码: 全选
sendmail_path ="/bin/femail -t -i"代码: 全选
;sendmail_from = me@example.com代码: 全选
sendmail_from = leo@gobsd.org代码: 全选
# cp /bin/sh /var/www/bin
# cp /etc/resolv.conf /var/www/etc/resolv.conf
# cp /etc/hosts /var/www/etc/hosts遗留问题，目前不能在chroot环境里用femail外发论坛email地址验证邮件，有知道的朋友请跟贴说明，查询 /var/www/logs/error_log, 显示：“femail: remote host refuses our greeting” ，不知道是哪里配置的问题，是否当垃圾邮件拒收了，看来邮件服务器这块还真要琢磨一下了。
