编译安装的注意事项

编译安装的四大步骤：

软件下载  ->  预编译  ->  编译  ->  配置

一、安装必备的编译工具：

yum install -y gcc gcc-c++ autoconf automake make

否则在预编译的过程中会报如下错误：

[root@localhost nginx]# ./configure

checking for OS
 + Linux 3.10.0-514.26.2.el7.x86_64 x86_64
checking for C compiler ... not found

./configure: error: C compiler cc is not found

二、安装pcre库，用来支持rewrite功能

yum install -y pcre-devel pcre

否则在预编译的过程中会出现以下问题：

checking for PCRE library ... not found
checking for PCRE library in /usr/local/ ... not found
checking for PCRE library in /usr/include/pcre/ ... not found
checking for PCRE library in /usr/pkg/ ... not found
checking for PCRE library in /opt/local/ ... not found

./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.

特别的：

在进行nginx编译安装的时候，Nginx需要整合pcre库，需要指定pcre源码目录，而不是pcre编译完成之后的路径，否则回报错

./configure --with-pcre=./auto/lib/pcre
