以下都以centos为例
1. nginx安装
1) 依赖安装
# yum install -y zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc
2) 下载nginx本体及缓存module
ngx_cache_purge http://labs.frickle.com/nginx_ngx_cache_purge/
nginx http://nginx.org
3) 创建用户
# useradd nginx
4) 编译nginx及安装
以上下载的2个文件放置在/home/nginx目录下, 并解压
进入nginx目录(不同版本名称不一样), 执行编译前配置, 注意修改最后的ngx_cache_purge插件版本
# ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_ssl_module --with-http_sub_module --with-http_stub_status_module --add-module=../ngx_cache_purge-x.x
# make
# make install
5) 配置nginx
参考 附件nginx.conf
6) 创建缓存目录
以nginx配置文件中设置的目录为准
7) 启动及关闭
在安装时已配置运行用户为nginx, 必须使用root用户启动, 进程将属于nginx用户
启动
/usr/local/nginx/sbin/nginx
关闭
/usr/local/nginx/sbin/nginx -s stop
重新读取配置
/usr/local/nginx/sbin/nginx -s relo
8) 设置开机自启动
在/etc/rc.local目录中增加启动命令即可
也可以使用centos7以后支持的systemctl
9) 防火墙放行nginx侦听端口
centos7以下使用iptables相关命令
centos7以上使用firewall-cmd相关命令
注: 若后端服务器为tomcat注意在/etc/rc.local中先执行source /etc/profile引入JDK配置(前提是JDK的JAVA_HOME等变量设置在profile文件内)
