一、问题描述
在linux安装nginx版本没有安装成功，报出一连串的环境变量关键词没有找到，如“...checking for sys/filio.h ... not found...not found.../dev/poll ... not found..kqueue..crypt()..F_READAHEAD..F_NOCACHE../usr/include/pcre/.../configure: error: the HTTP rewrite module requires the PCRE library...You can either disable the module by using --without-http_rewrite_module”,具体如下所示

通过在线和离线两种不同方式分别进行安装pcre、openssl,具体如下
1、pcre-8.34安装
方法一、在线方式安装
[root@raid2t soft]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz@b@--2018-08-24 01:33:11-- http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz@b@正在解析主机 downloads.sourceforge.net... 216.105.38.13@b@。。。@b@pcre-8.35/pcre16_valid_utf16.c@b@pcre-8.35/pcre32_ucd.c@b@pcre-8.35/makevp_l.txt@b@@b@[root@raid2t soft]# tar zxvf pcre-8.35.tar.gz@b@pcre-8.35/@b@pcre-8.35/pcre_scanner.h@b@pcre-8.35/LICENCE@b@pcre-8.35/makevp_c.txt@b@pcre-8.35/PrepareRelease@b@pcre-8.35/RunTest.bat@b@。。。@b@@b@[root@raid2t soft]# cd pcre-8.35@b@@b@[root@raid2t pcre-8.35]# ./configure@b@checking for a BSD-compatible install... /usr/bin/install -c@b@。。。@b@ Link pcretest with libreadline .. : no@b@ Valgrind support ................ : no@b@ Code coverage ................... : no@b@@b@[root@raid2t pcre-8.35]# make && make install@b@rm -f pcre_chartables.c@b@ln -s ./pcre_chartables.c.dist pcre_chartables.c@b@make all-am @b@ 。。。@b@ make[2]: Leaving directory '/home/soft/pcre-8.35'@b@make[1]: Leaving directory '/home/soft/pcre-8.35'
方法二、离线安装,安装pcre-8.34.tar.gz脚本,先下载安装pcre（pcre-8.34.tar.gz），安装步骤脚本如下
# tar zxvf pcre-8.34.tar.gz @b@ @b@# cd pcre-8.34 @b@ @b@#./configure @b@ @b@# make && make install
2.安装openssl
[root@raid2t nginx-1.6.3]# yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel@b@已加载插件：fastestmirror, refresh-packagekit@b@设置安装进程@b@Loading mirror speeds from cached hostfile@b@。。。@b@已安装:@b@ libtool.x86_64 0:2.2.6-15.5.el6 @b@ openssl-devel.x86_64 0:1.0.1e-57.el6 @b@ zlib-devel.x86_64 0:1.2.3-29.el6 @b@@b@作为依赖被安装:@b@ autoconf.noarch 0:2.63-5.1.el6 @b@ 。。。@b@@b@更新完毕:@b@ openssl.x86_64 0:1.0.1e-57.el6 @b@@b@作为依赖被升级:@b@ e2fsprogs.x86_64 0:1.41.12-24.el6 @b@ e2fsprogs-libs.x86_64 0:1.41.12-24.el6 @b@ krb5-libs.x86_64 0:1.10.3-65.el6 @b@ libcom_err.x86_64 0:1.41.12-24.el6 @b@ libss.x86_64 0:1.41.12-24.el6
3. 离线安装-安装openssl-1.0.0.e.tar.gz脚本，下载openssl（openssl-1.0.0e.tar.gz）包
# tar zxvf openssl-1.0.1j.tar.gz @b@ @b@# cd openssl-1.0.1j @b@ @b@#./config @b@ @b@# make && make install
