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。
