摘要：復(fù)制代碼報(bào)錯(cuò)信息如下錯(cuò)誤錯(cuò)誤解答執(zhí)行命令安裝依賴包。為了讓讀者理解問題，重現(xiàn)上述錯(cuò)誤過程，命令如下復(fù)制代碼

1、Nginx安裝過程報(bào)錯(cuò)
錯(cuò)誤一：軟件依賴包未正確安裝問題---PCRE依賴包沒有安裝

  ./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= option.

解決方法：yum install pcre pcre-devel -y
錯(cuò)誤二：軟件依賴包未正確安裝問題---OPENSSL依賴包沒有安裝
./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= option.

解決方法：yum install openssl openssl-devel -y
錯(cuò)誤三：編譯安裝pcre編譯軟件時(shí)，gcc不全導(dǎo)致報(bào)錯(cuò)（使用yum安裝不存在此問題)。
復(fù)制代碼
報(bào)錯(cuò)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]錯(cuò)誤 1
make[l]:Leaving directory /home/gjlin/tools/pcre-8.30
make : * [all]錯(cuò)誤 2

解答：執(zhí)行"yum -y install gcc-c++"命令安裝gcc-c++依賴包。

2、Nginx啟動(dòng)過程中報(bào)錯(cuò)
錯(cuò)誤一：nginx軟件重復(fù)啟動(dòng)產(chǎn)生的錯(cuò)誤信息
復(fù)制代碼
[root@web01 nginx-1.10.2]# /application/nginx/sbin/nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

解決方法：nginx軟件已經(jīng)啟動(dòng)無需反復(fù)啟動(dòng)，如果需要重新啟動(dòng)需要停止nginx進(jìn)程或者用reload方式進(jìn)行重啟

復(fù)制代碼
錯(cuò)誤二：403報(bào)錯(cuò)
服務(wù)阻止客戶端訪問
服務(wù)端站點(diǎn)目錄中，沒有指定首頁文件信息
錯(cuò)誤三：?jiǎn)?dòng) Nginx 時(shí)如下報(bào)錯(cuò)"nginx:[emerg]getpwnam(“nginx”)failed"
解答：這是因?yàn)闆]有對(duì)應(yīng)的Nginx服務(wù)用戶，執(zhí)行useradd nginx -s /sbin/nologin -M創(chuàng)建Nginx用戶即可。為了讓讀者理解問題，重現(xiàn)上述錯(cuò)誤過程，命令如下：

復(fù)制代碼
[root@web tools]# pkill nginx

[root@web tools]# userdel nginx

[root@web tools]# /application/nginx/sbin/nginx

nginx: [emerg] getpwnam(Mnginx") failed

[root@web tools]# useradd nginx -s /sbin/nologin -M

[root@web tools]# /application/nginx/sbin/nginx
