1.安装基础环境包（如果已安装，可更新） yum -y :自动选择y
yum -y install openssl*
yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel
yum -y install libxml2 libxml2-devel zlib zlib-devel ncurses ncurses-devel curl curl-devel
yum -y install gd gd2 gd-devel gd2-devel
yum –y install gcc gcc-c++
注：本人在安装过程发生一个错误，提示
/var/run/yum.pid 已被锁定，PID 为 xxxx 的另一个程序正在运行
该解决办法：直接在终端运行 rm -f /var/run/yum.pid 将该文件删除，然后再次运行yum。
2. 安装 pcre
1 ) 使用rz命令从主机下载pcre-8.38.zip文件(前提是主机上有该文件)
2） 解压pcre-8.38.zip
unzip pcre-8.38.zip
3）安装
cd pcre-8.38
./configure
make
make install
3. 下载Nginx1.9.9 ，解压安装 （注：本人习惯将下载位置放于/tmp 下）
wget http://nginx.org/download/nginx-1.9.9.tar.gz
tar -zxvf nginx-1.9.9.tar.gz
cd nginx-1.9.9/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/application/pcre
#注: 由于安装pcre没有指定目录，因此不用指定--with-pcre。若安装pcre有指定路径，--with-pcre也要指定路径
make
make install
4. 配置Nginx
cd /usr/local/nginx/conf
-> vim nginx.conf
user www www;
worker_processes auto;
worker_rlimit_nofile 204800;
#error_log logs/error.log;
#error_log logs/error.log notice;

附 ： 一些nginx有关基本命令
-> /usr/local/nginx/sbin/nginx 启动
-> /usr/local/nginx/sbin/nginx -t 测试配置文件
-> /usr/local/nginx/sbin/nginx -s reload 重启
-> /usr/local/nginx/sbin/nginx -v 查看nginx版本
-> /usr/local/nginx/sbin/nginx -V 查看nginx版本，及配置信息
-> netstat -antlp | grep 80 nginx占用80端口，检查是否启动
-> ps -ef | grep nginx 命令ps查找nginx的主进程号，检查是否启动(假设主进程号为3514)
-> kill -QUIT 3514 从容停止
-> kill -TERM 3514 快速停止
-> kill -9 3514 强制停止，只关闭一个主进程号，其余进程号仍在运行
-> kill -9 3514 3515 3525 强制关闭nginx所有进程号
-> kill -HUP 3514 平滑重启
