Nginx服务器的编译安装与配置过程

系统：Centos 6.0

一、安装之前首先确认系统中是否已安装gcc、openssl-devel、pcre-devel、zlib-devel

#yum -y install gcc openssl-devel pcre-devel zlib-devel

二、安装pcre-devel库（使Nginx支持http rewrite的模块）

      #tar zxvf pcre-8.31.tar.gz

#cd pcre-8.31

#./congigure

#make

#make install

问题：

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++编译包

   解决方法：需要先安装libtool和gcc-c++

   #yum -y install libtool

   #yum -y install gcc-c++

三、安装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 可以用来启用Nginx的NginxStatus功能，以监控Nginx的当前状态。

--with-http_gzip_static_module 支持在线实时压缩输出数据流。

问题：

1、若在./configure后配置刚才的参数，提示一下的错误：

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

解决方法：

./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换成你的pcre解压缩包的路径

 

2、若在“./configure”后方加入了“--with-http_gzip_static_module”（添加gzip压缩模块）提 示以下错误：

./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.

 

解决办法：安装zlib-devel包

#yum -y install  zlib-devel

启动Nginx出现的问题：

# /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 从错误看出是缺少lib文件导致，进一步查看下 # 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 并没有找到，进入/lib目录中手动链接下

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

然后在启动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启动失败，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)

解决如下图所示：

先用#netstat -ntlp 查看端口被哪个服务给占用

其次用#kill -9 PID   杀掉进程号  （进程号杀不死用 killall -9）

在启用nginx 

打开浏览器：http://localhost 显示Welcome to Nginx

至此Nginx安装完毕。
