安装nginx时遇到的问题及解决方案

今天在安装nginx时出现如下错误：

[root@node1 nginx-0.8.55]# ./configure \
  --prefix=/usr \
  --sbin-path=/usr/sbin/nginx \
  --conf-path=/etc/nginx/nginx.conf \
  --error-log-path=/var/log/nginx/error.log \
  --pid-path=/var/run/nginx/nginx.pid  \
  --lock-path=/var/lock/nginx.lock \
  --user=nginx \
  --group=nginx \
  --with-http_ssl_module \
  --with-http_flv_module \
  --with-http_gzip_static_module \
  --http-log-path=/var/log/nginx/access.log \
  --http-client-body-temp-path=/var/tmp/nginx/client/ \
  --http-proxy-temp-path=/var/tmp/nginx/proxy/ \
  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/

报错信息：

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

上面步骤很明显缺少了一个叫pcre的库文件，安装好后并指定路径，我们接着安装。

[root@node1 pcre-8.02]# ./configure --prefix=/usr/local/pcre
[root@node1 pcre-8.02]# make && make install

安装正常后，我们接着安装nginx。

[root@node1 nginx-0.8.55]# ./configure \
  --prefix=/usr \
  --sbin-path=/usr/sbin/nginx \
  --conf-path=/etc/nginx/nginx.conf \
  --error-log-path=/var/log/nginx/error.log \
  --pid-path=/var/run/nginx/nginx.pid  \
  --lock-path=/var/lock/nginx.lock \
  --user=nginx \
  --group=nginx \
  --with-http_ssl_module \
  --with-http_flv_module \
  --with-http_gzip_static_module \
  --http-log-path=/var/log/nginx/access.log \
  --http-client-body-temp-path=/var/tmp/nginx/client/ \
  --http-proxy-temp-path=/var/tmp/nginx/proxy/ \
  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
  --with-pcre=/usr/local/pcre

当使用make时报了如下错误：

[root@node1 nginx-0.8.55]# make
make -f objs/Makefile
make[1]: Entering directory `/nginx/nginx-0.8.55' 
cd /usr/local/pcre && if [ -f Makefile ]; then make distclean; fi && CC="gcc" CFLAGS="" ./configure --disable-shared 
/bin/sh: line 2: ./configure: 没有那个文件或目录 
make[1]: *** [/usr/local/pcre/Makefile] 错误 127 
make[1]: Leaving directory `/nginx/nginx-0.8.55'
make: *** [build] 错误 2

通过查阅资料发现，原来在检测环境时，nginx的configure脚本指向的不是pcre的安装后目录，而是指向了pcre的源目录。正确的做法应该是指向pcre的安装目录，如下所示：

[root@node1 nginx-0.8.55]# ./configure \
  --prefix=/usr \
  --sbin-path=/usr/sbin/nginx \
  --conf-path=/etc/nginx/nginx.conf \
  --error-log-path=/var/log/nginx/error.log \
  --pid-path=/var/run/nginx/nginx.pid  \
  --lock-path=/var/lock/nginx.lock \
  --user=nginx \
  --group=nginx \
  --with-http_ssl_module \
  --with-http_flv_module \
  --with-http_gzip_static_module \
  --http-log-path=/var/log/nginx/access.log \
  --http-client-body-temp-path=/var/tmp/nginx/client/ \
  --http-proxy-temp-path=/var/tmp/nginx/proxy/ \
  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
  --with-pcre=/usr/local/pcre-8.02
[root@node1 nginx-0.8.55]# make && make install

OK! 安装成功。
