linux安装nginx
nginx下载地址：https://nginx.org/download/
下载“nginx-1.9.9.tar.gz”，移动到/usr/local/src/下。
## 解压
tar -zxvf nginx-1.9.9.tar.gz
##进入nginx目录
cd nginx-1.9.9
## 配置
./configure --prefix=/usr/local/nginx
这一步可能报错：
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
因为缺失依赖，安装依赖：yum -y install pcre-devel openssl openssl-devel
再执行一下./configure --prefix=/usr/local/nginx
# make
make
make install
# cd到刚才配置的安装目录/usr/loca/nginx/
./sbin/nginx -t
输出：
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file
/usr/local/nginx/conf/nginx.conf test is successful
启动nginx
cd /usr/local/nginx/sbin
./nginx //启动nginx
linux测试：
curl http://127.0.0.1:80
[root@iZ8vbacq1jxnaby0lsk8a6Z sbin]# curl http://127.0.0.1:80
