# yum install zlib zlib-devel
# yum install openssl openssl-devel
# groupadd nginx
# useradd -g nginx nginx
# mkdir /software
# cd /software
# wget http://nginx.org/download/nginx-1.13.1.tar.gz
# tar xzf nginx-1.13.1.tar.gz
# cd nginx-1.13.1
安装相关依赖包
[root@ns1 nginx-1.13.1]# yum install libxml2-devel libxslt-devel gd-devel
[root@ns1 nginx-1.13.1]# yum install perl perl-devel perl-ExtUtils-Embed libatomic_ops-devel
[root@ns1 nginx-1.13.1]# ./configure --user=nginx --group=nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --with-select_module --with-poll_module --with-file-aio --with-ipv6 --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_p_w_picpath_filter_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_auth_request_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_stub_status_module --with-http_perl_module --with-mail --with-mail_ssl_module --with-cpp_test_module --with-cpu-opt=CPU --with-pcre --with-pcre-jit --with-zlib-asm=CPU --with-libatomic --with-debug --with-ld-opt="-Wl,-E" --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi
[root@ns1 nginx-1.13.1]#

将启动脚本（见附件）上传到/etc/init.d/ 目录下面
# chmod +x /etc/init.d/nginx
# chkconfig --add nginx
# chkconfig nginx on
# chkconfig --list nginx
# mkdir -p /var/tmp/nginx/client
编辑配置文件，红色字体为修改或添加后的项目

# location / {

}
检测配置文件是否有语法错误
[root@host-cn tmp]# nginx -t -c /etc/nginx/nginx.conf
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
加入防火墙允许
[root@ns1 nginx]# firewall-cmd --add-service=http --permanent
[root@ns1 nginx]# firewall-cmd --reload
[root@ns1 nginx]# systemctl restart firewalld
启动nginx服务
[root@ns1 nginx]# service nginx start
再用户就可以使用IP 110.110.220.54直接访问网站了。
-----------------------------------------------------------------------------------
反向代理的应用
公司同事，用tomcat发布了2个项目，可以用IP访问他的项目
A项目地址 http://110.110.220.54:8080/dy/jsp/index.jsp
B项目地址 http://110.110.220.54:8080/dy/position/login.jsp
现在使用nginx，用公司域名www.dongying.com来发布他的项目，方法如下：
绿色部分为项目A，设定正常后用www.dongying.com来访问。
橙色部分为项目B，设定正常后用www.dongying.com:8080/dy/position/login.jsp来访问。
server {
listen 80;
server_name www.dongying.com;
charset utf-8;
location / {
proxy_pass http://www.dongying.com:8080/dgmy/jsp/;
index index.html index.htm index.jsp login.jsp;
}
location ~ \.(gif|jpg|jpeg|png|bmp|swf|css|js)$
{
access_log off;
expires 1d;
root /opt/tomcat/webapps/dy/;
break;
}
location /dy/position/ {
proxy_pass http://www.dongying.com:8080/dy/position/login.jsp;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 100m;
root html;
index index.html index.htm index.jsp login.jsp;
}
