一、安装编译工具及库文件
依赖库安装，一定要按照顺序安装：
(1) 如果没有安装c++编译环境
yum install gcc-c++
(2) ssl 功能需要 openssl 库
wget https://www.openssl.org/source/openssl-1.1.0f.tar.gz tar -zxvf openssl-1.1.0f.tar.gz cd openssl-1.1.0f ./config make && make install
(3) rewrite 模块需要 pcre 库
wget https://ftp.pcre.org/pub/pcre/pcre-8.01.tar.gz tar -zxvf pcre-8.01.tar.gz cd pcre-8.01 ./configure make && make install
(4) gzip 模块需要 zlib 库
wget https://nchc.dl.sourceforge.net/project/libpng/zlib/1.2.11/zlib-1.2.11.tar.gz tar -zxvf zlib-1.2.11.tar.gz cd zlib-1.2.11 ./configure make && make install
(4) nginx安装
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 --prefix=/usr/local/nginx make && make install
二、设置依赖库连接
如果输入语句：./usr/local/nginx/sbin/nginx出现错误：
error while loading shared libraries: libpcre.so.0: cannot open shared object file: no such file or directory
可输入：
whereis libpcre.so.1
结果：libpcre.so: /lib64/libpcre.so.1 /usr/local/lib/libpcre.so /usr/local/lib/libpcre.so.0
再使用ln命令，将libpcre.so.0，libpcre.so和libpcre.so.1连接到lib64目录下：
ln -s /usr/local/lib/libpcre.so.0 /lib64
三、nginx 配置
创建 nginx 运行使用的用户 www：
/usr/sbin/groupadd www /usr/sbin/useradd -g www www
配置ngix.conf, 输入：vi /usr/local/webserver/nginx/conf/nginx.conf的内容修改为：
user www www;
worker_processes 2;
error_log ../error.log;
pid /usr/local/nginx/nginx.pid;
worker_rlimit_nofile 65535;
events
{
use epoll;
worker_connections 65535;
}
http
{
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
server
{
listen 80;//端口
server_name localhost;//域名
index test.html index.htm index.php;//解析网页名称
root /usr/local/nginx/html; #站点目录
location ~ .*\.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$
{
expires 30d;
# access_log off;
}
location ~ .*\.(js|css)?$
{
expires 15d;
# access_log off;
}
access_log off;
}
}检查配置是否正确：
/usr/local/webserver/nginx/sbin/nginx -t
启动：/usr/local/webserver/nginx/sbin/nginx
监听进程：ps -ef|grep nginx
访问服务器ip: 192.168.1.23
问题：配置正确时，也会出现ip地址无法访问的情况：
可以通过阿里云服务器，esc服务器->安全组->配置规则->添加规则，进行配置即可。
