Nginx 安裝與配置

系統：Centos 6.0

下載下傳nginx(nginx-1.2.4.tar.g)   http://nginx.org/ 下載下傳pcre(pcre-8.31.tar.gz)    http://pcre.org/   一、安裝之前首先确認系統中是否已安裝gcc、openssl-devel、pcre-devel、zlib-devel        #yum -y install gcc openssl-devel pcre-devel zlib-devel   二、安裝pcre-devel庫（使Nginx支援http rewrite的子產品）       #tar zxvf pcre-8.31.tar.gz

      #cd pcre-8.31

      #./congigure

      #make

      #make install           問題：

    libtool: compile: unrecognized option `-DHAVE_CONFIG_H’

    libtool: compile: Try `libtool –help’ for more information.

    make[1]: *** [pcrecpp.lo] Error 1

    make[1]: Leaving directory `/home/guangbo/work/pcre-8.12’

    make: *** [all] Error 2

   缺少gcc-c++和libtool，也就是c++編譯包

   解決方法：需要先安裝libtool和gcc-c++

   #yum -y install libtool

   #yum -y install gcc-c++   三、安裝Nginx

   #tar zxvf nginx-1.2.4.tar.gz

   #cd nginx-1.2.4

   #./configure –with-http_stub_status_module –with-http_gzip_static_module

     – prefix=/usr/local/nginx

   #make

   #makeinstall

   注：–with-http_stub_status_module 可以用來啟用Nginx的NginxStatus功能，以監控Nginx的目前狀态。

           –with-http_gzip_static_module 支援線上實時壓縮輸出資料流。      問題：   1、若在./configure後配置剛才的參數，提示一下的錯誤：   objs/src/http/modules/ngx_http_browser_module.o \

objs/src/http/modules/ngx_http_upstream_ip_hash_module.o \

objs/src/http/modules/ngx_http_upstream_least_conn_module.o \

objs/src/http/modules/ngx_http_upstream_keepalive_module.o \

objs/ngx_modules.o \

-lpthread -lcrypt -lpcre -lcrypto -lcrypto -lz

objs/src/core/ngx_regex.o: In function `ngx_pcre_free_studies’:

/share/nginx-1.2.4/src/core/ngx_regex.c:307: undefined reference to `pcre_free_study’

collect2: ld returned 1 exit status

make[1]: *** [objs/nginx] Error 1

make[1]: Leaving directory `/share/nginx-1.2.4’

make: *** [build] Error 2   解決方法： ./configure –prefix=/usr/local/nginx –without-http_autoindex_module –without-http_geo_module –without-http_map_module –without-http_browser_module –with-http_stub_status_module –with-http_realip_module  –with-pcre=../pcre-8.31   PS:   ./configure –prefix=/usr/localnx –without-http_autoindex_module –without-http_geo_module –with-pcre=../pcre-8.31   注意：把–with-pcre=../pcre-8.31換成你的pcre解壓縮包的路徑

   2、若在“./configure”後方加入了“–with-http_gzip_static_module”（添加gzip壓縮子產品）提 示以下錯誤：

./configure: error: the HTTP gzip module requires the zlib library.

You can either disable the module by using –without-http_gzip_module

option, or install the zlib library into the system, or build the zlib library

statically from the source with nginx by using –with-zlib=<path> option.

  解決辦法：安裝zlib-devel包 #yum -y install  zlib-devel     啟動Nginx出現的問題：

# /usr/local/nginx/sbin/nginx

1、/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

從錯誤看出是缺少lib檔案導緻，進一步檢視下

# ldd $(which /usr/local/nginx/sbin/nginx)

linux-gate.so.1 => (0x0071b000)

libpthread.so.0 => /lib/libpthread.so.0 (0×00498000)

libcrypt.so.1 => /lib/libcrypt.so.1 (0×00986000)

libpcre.so.1 => not found

libcrypto.so.6 => /lib/libcrypto.so.6 (0×00196000)

libz.so.1 => /lib/libz.so.1 (0×00610000)

libc.so.6 => /lib/libc.so.6 (0x002d7000)

/lib/ld-linux.so.2 (0x006a8000)

libdl.so.2 => /lib/libdl.so.2 (0x008c3000)

可以看出 libpcre.so.1 => not found 并沒有找到，進入/lib目錄中手動連結下

# ln -s libpcre.so.0.0.1 libpcre.so.1

  然後在啟動nginx ok 了

# /usr/local/nginx/sbin/nginx

# ps -aux|grep nginx

Warning: bad syntax, perhaps a bogus ‘-‘? See /usr/share/doc/procps-3.2.7/FAQ

root 28254 0.0 0.0 2688 460 ? Ss 17:16 0:00 nginx: master process /usr/local/nginx/sbin/nginx

nobody 28255 0.0 0.0 2860 816 ? S 17:16 0:00 nginx: worker process

root 28265 0.0 0.0 4160 688 pts/1 R+ 17:16 0:00 grep nginx   2、Nginx啟動失敗，提示端口已被占用提示：

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)

  解決如下圖所示： 先用#netstat -ntlp 檢視端口被哪個服務給占用 其次用#kill -9 PID   殺掉程序号  （程序号殺不死用 killall -9） 在啟用nginx 

  打開浏覽器： http://localhost 顯示Welcome to Nginx

至此Nginx安裝完畢。
