1.安装依赖的其他包
（0）gcc gcc-c++
yum install gcc-c++
##yum install -y make cmake gcc gcc-c++
（1）zlib
wget http://zlib.net/zlib-1.2.11.tar.gz
tar zxvf zlib-1.2.11.tar.gz
cd zlib-1.2.11
./configure && make && make install
（2）pcre
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.40.tar.gz
tar zxvf pcre-8.40.tar.gz
cd pcre-8.40
./configure && make && make install
（3）openssl
wget http://www.openssl.org/source/openssl-fips-2.0.10.tar.gz
tar zxvf openssl-fips-2.0.10.tar.gz
cd openssl-fips-2.0.10
./config && make && make install
2.安装nginx
wget http://nginx.org/download/nginx-1.12.1.tar.gz
tar zxvf nginx-1.12.1.tar.gz
cd nginx-1.12.1
./configure && make && make install
nginx安装到/usr/local/nginx
3.nginx配置
启动nginx
[root@pre-srv44 nginx]# /usr/local/nginx/sbin/nginx
/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
[root@pre-srv44 nginx]# whereis libpcre.so.1
libpcre.so: /lib64/libpcre.so.0 /usr/local/lib/libpcre.so.1 /usr/local/lib/libpcre.so
[root@pre-srv44 nginx]# ln -s /usr/local/lib/libpcre.so.1 /lib64
[root@pre-srv44 nginx]# /usr/local/nginx/sbin/nginx
[root@pre-srv44 lib64]# ps -aux | grep nginx
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQ
root 14711 0.0 0.0 20404 652 ? Ss 22:57 0:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody 14712 0.0 0.0 20848 1260 ? S 22:57 0:00 nginx: worker process
root 14714 0.0 0.0 103252 840 pts/0 S+ 22:57 0:00 grep nginx
[root@pre-srv44 lib64]#
如果要关闭nginx，我们可以使用如下命令：
/usr/local/nginx/sbin/nginx -s stop
如果想要重新热启动nginx，则使用如下命令：
/usr/local/nginx/sbin/nginx -s reload
/usr/local/nginx/sbin/nginx -s reload # 重新载入配置文件
/usr/local/nginx/sbin/nginx -s reopen # 重启 Nginx
4.测试nginx
通过浏览器访问nginx欢迎页，在地址栏输入：http://192.168.31.241/（80端口可以不用输）或http://192.168.156.11:80/，如下图所示。

另：关于nginx的工作用户
安装时 ./configure --user=www-data --group=www-data --with-http_ssl_module --with-http_realip_module
nginx工作进程在www-data组中的www-data用户下运行
