1、Nginx安装过程报错错误一：软件依赖包未正确安装问题---PCRE依赖包没有安装
./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.解决方法：yum install pcre pcre-devel -y
错误二：软件依赖包未正确安装问题---OPENSSL依赖包没有安装
./configure: error: SSL modules require the OpenSSL library.
You can either do not enable the modules, or install the OpenSSL library
into the system, or build the OpenSSL library statically from the source
with nginx by using --with-openssl=<path> option.解决方法：yum install openssl openssl-devel -y
错误三：编译安装pcre编译软件时，gcc不全导致报错（使用yum安装不存在此问题)。
报错信息如下：
[root@gjlin2 pcre-8.30]# make && make install
make all-am
make[l]: Entering directory 7h〇me/gjlin/tools/pcre-8.30*
CXX pcrecpp.lo
libtool: compile : unrecognized option '-DHAVE_CONFIG_H'
libtool:compile : Try 'libtool --help' for more information.
make[l]：***[pcrecpp.lo]错误
make[l]:Leaving directory '/home/gjlin/tools/pcre-8.30'
make : *** [all]错误 解答：执行"yum -y install gcc-c++"命令安装gcc-c++依赖包。
2、Nginx启动过程中报错错误一：nginx软件重复启动产生的错误信息
[root@web01 nginx-1.10.]# /application/nginx/sbin/nginx
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] still could not bind()
解决方法：nginx软件已经启动无需反复启动，如果需要重新启动需要停止nginx进程或者用reload方式进行重启
错误二：403报错
- 服务阻止客户端访问
- 服务端站点目录中，没有指定首页文件信息
错误三：启动 Nginx 时如下报错"nginx:[emerg]getpwnam(“nginx”)failed"
./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.解决方法：yum install pcre pcre-devel -y

错误三：启动 Nginx 时如下报错"nginx:[emerg]getpwnam(“nginx”)failed"
解答：这是因为没有对应的Nginx服务用户，执行useradd nginx -s /sbin/nologin -M创建Nginx用户即可。为了让读者理解问题，重现上述错误过程，命令如下：
[root@web tools]# pkill nginx[root@web tools]# userdel nginx[root@web tools]# /application/nginx/sbin/nginxnginx: [emerg] getpwnam(Mnginx") failed[root@web tools]# useradd nginx -s /sbin/nologin -M[root@web tools]# /application/nginx/sbin/nginx
