1、下载pcre， 是一个用c语言编写的正则表达式函数库
[root@localhost pcre-8.36]# cd /tmp/download/ [root@localhost download]# wget http://nchc.dl.sourceforge.net/project/pcre/pcre/8.37/pcre-8.37.tar.gz [root@localhost download]# tar zxvf pcre-8.36.tar.gz
2、下载zlib库
[root@localhost pcre-8.36]# cd /tmp/download/ [root@localhost download]# wget http://ncu.dl.sourceforge.net/project/libpng/zlib/1.2.8/zlib-1.2.8.tar.gz [root@localhost download]# tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8
4、下载ssl
[root@localhost zlib-1.2.8]# cd .. [root@localhost download]# wget http://www.openssl.org/source/openssl-1.0.1p.tar.gz [root@localhost download]# cd openssl-1.0.1c [root@localhost openssl-1.0.1c]# tar -zxvf openssl-1.0.1c.tar.gz
5、下载nginx
[root@localhost download]# wget http://nginx.org/download/nginx-1.2.8.tar.gz [root@localhost download]# tar -zxvf nginx-1.2.8.tar.gz
6、安装
[root@localhost download]mv pcre-8.36 /usr/local/ [root@localhost download]mv zlib-1.2.8 /usr/local/ [root@localhost download]mv openssl-1.0.1c /usr/local/ [root@localhost download]mv nginx-1.2.8 /usr/local/ [root@localhost download]cd /usr/local/ [root@localhost local]# cd pcre-8.36 [root@localhost pcre-8.36]# ./configure&&make&&make install [root@localhost pcre-8.36] cd ../zlib-1.2.8 [root@localhost zlib-1.2.8]# ./configure && make && make install [root@localhost zlib-1.2.8]# cd ../openssl-1.0.1c [root@localhost openssl-1.0.1c]# ./config && make && make install [root@localhost openssl-1.0.1c]# cd ../nginx-1.2.8 [root@localhost nginx-1.2.8]# ./configure --prefix=/usr/local/nginx && make && make install
添加以下shell脚本。
#!/bin/bash

# it is v.0.0.2 version.
# chkconfig: - 85 15

exit 1

echo -n $"starting $prog: "

killproc $nginxd
retval=$?
echo
[ $retval = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid
}
# reload nginx service functions.

echo -n $"reloading $prog: "

echo $"usage: $prog {start|stop|restart|reload|status|help}"
exit 1
esac
exit $retval保存后，设置权限让所有人可以操作。
[root@localhost ~]# chmod a+x /etc/init.d/nginx [root@localhost logs]# /etc/init.d/nginx status nginx (pid 2417 2416) is running... [root@localhost logs]# /etc/init.d/nginx stop stopping nginx: [ ok ] [root@localhost logs]# /etc/init.d/nginx start starting nginx: [ ok ] [root@localhost logs]# /etc/init.d/nginx status nginx (pid 2454 2452) is running...

}2、启动nginx失败
[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf /usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: no such file or directory
原因是64bit的系统，但是默认取了/usr/local/lib里面的包
检查方法：
[root@localhost nginx]# cd /usr/local/ [root@localhost local]# ls /lib64/ |grep pcre libpcre.so.0 libpcre.so.0.0.1 [root@localhost local]# ls /lib/ |grep pcre
说明缺失的包在lib64
设置软连接来解决：
[root@localhost local]# ln -s /lib64/libpcre.so.0.0.1 /lib64/libpcre.so.1 [root@localhost local]# cd nginx [root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
3、启动报错：
报错：nginx: [emerg] bind() to 0.0.0.0:80 failed (98: address already in use)
解决办法：sudo fuser -k 80/tcp
端口被占用，关闭占用端口
