Nginx 部署与配置
目录
1.Nginx 下载地址
http://nginx.org/en/download.html
2.Nginx 安装配置
##安装Nginx依赖，pcre、openssl、gcc、zlib（推荐使⽤yum源⾃动安装）
yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel
##解包Nginx软件包
tar -xvf nginx-1.17.8.tar
##进⼊解压之后的⽬录 nginx-1.17.8
cd nginx-1.17.8
##命令⾏执⾏
./configure
##命令⾏执⾏
make
##命令⾏执⾏
make install ##完毕之后在/usr/local/下会产⽣⼀个nginx⽬录
##进⼊sbin⽬录中，执⾏启动nginx命令
./nginx ##启动Nginx
./nginx -s stop ## 终止Nginx
./nginx -s reload ## 重新加载Nginx.conf的配置文件3.Nginx配置文件详解
#=================================start,全局块,从开始到evennts块之间的内容==================================================
# 运行用户
#user nobody;
# worker 进程数量,通常设置于cpu的数量相等
worker_processes 1;
# 全局错误日志以及pid文件位置
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#====指的是marst主进程pid
#pid logs/nginx.pid;
#================================ end全集块 ===================================================================================
#===============================start,events事件块（影响nginx服务器和用户的网络连接）==========================================
events {
#单个worker进程的最大并发连接数
worker_connections 1024;
}
#==============================end,events事件块===============================================================================
#==============================start,http块（nginx服务器中配置最频繁的部分，端口监听，请求转发等）===========================
http {
#以内mime类型定义文件

4.Nginx安装产生的问题记录
4.1.启动Nginx本地能访问但是远程调用没响应
问题排查
查看防火墙是否关闭：
#查看防火墙是否关闭 适用于CentOS 6.5版本
service iptable status
#查看防火墙是否关闭 适用于CentOS 7.2版本
firewall-cmd --state
systemctl status firewalld.service
#关闭防火墙 适用于CentOS 6.5版本
servcie iptables stop #临时关闭
chkconfig iptables off #永久关闭
#关闭防火墙 适用于CentOS 7.2版本
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动
#CentOS 7 以下版本 iptables 命令
#如要开放80，22，8080 端口，输入以下命令即可
/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 22 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
#然后保存：
/etc/rc.d/init.d/iptables save
