1、安装nginx
tar zxvf nginx-1.8.1.tar.gz
cd nginx-1.8.1
./configure
make
make install
/usr/local/nginx/sbin/nginx 开启权限
/usr/local/nginx/sbin/nginx -s stop 关闭权限
/usr/local/nginx/sbin/nginx -s reload 重新加载配置文件
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
---------------------------------
出现错误
checking for PCRE library ... not found
checking for PCRE library in /usr/local/ ... not found
2、安装pcre
tar zxvf pcre-8.38.tar.gz
cd pcre-8.38
./configure
make
make install
出现错误
安装pcre报错“You need a C++ compiler for C++ support.”
3、安装GCC C++
yum install -y gcc-c++
4、启动nginx
出现错误
nginx无法启动提示libpcre.so.1: cannot open shared object file
大概可以看得出来，缺少了libpcre这个库文件
解决方法：
[root@bogon lib64]# ln -s /usr/local/lib/libpcre.so.1 /lib64
