本来是打算研究nginx+varnish的,没想到我居然在编译安装varnish的时候出错,想起以前研究varnish反向代理出现过相同的问题,所以解决起来很快,看来有时候解决过的问题还是要保存起来,免得下次忘了又去到处找.

　　系统:centos 5.5

　　软件:varnish-2.1.5.tar.gz

　　编译安装出现的错误:

　　configure: WARNING: xsltproc not found ?not building documentation

　　checking for rst2man... no

　　checking for rst2man.py... no

　　configure: WARNING: rst2man not found ?not building man pages

　　checking for clock_gettime in -lrt... yes

　　checking for dlopen in -ldl... yes

　　checking for library containing initscr... no

　　configure: WARNING: curses not found; some tools will not be built

　　checking for library containing pthread_create... -lpthread

　　checking for socket in -lsocket... no

　　checking for getaddrinfo in -lnsl... yes

　　checking for cos in -lm... yes

　　checking for pkg-config... no

　　checking for PCRE... no

　　configure: error: in `/root/varnish-2.1.5':

　　configure: error: The pkg-config script could not be found or is too old.  Make sure it

　　is in your PATH or set the PKG_CONFIG environment variable to the full

　　path to pkg-config.

　　Alternatively, you may set the environment variables PCRE_CFLAGS

　　and PCRE_LIBS to avoid the need to call pkg-config.

　　See the pkg-config man page for more details.

　　To get pkg-config, see <http://pkg-config.freedesktop.org/>.

　　See `config.log' for more details

　　当出现上面的错误时,说明你没有安装pkgconfig,或者是你的环境变量有问题,环境变量有问题的可以自己去改下,没有安装的可以使用下面这条命令:

　　yum -y install automake autoconf libtool ncurses-devel libxslt groff pcre-devel pkgconfig

　　因为有些服务商给装的是精简版的,所以会出现好多组件没有安装.好了,接下来就不用我说了.
