Linux安装Nginx

#一键安装下面四个依赖
yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

#nginx安装地址：http://nginx.org/download
#下载tar包
wget http://nginx.org/download/nginx-1.13.7.tar.gz
#解压tar包
tar -zxvf nginx-1.13.7.tar.gz

#执行命令 考虑到后续安装ssl证书 添加两个模块
./configure --with-http_stub_status_module --with-http_ssl_module --prefix=/usr/local/nginx

#编译
make & make install

#启动
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

#查看nginx进程是否启动：
ps -ef | grep nginx
#结束进程
kill -9 [id]

#如果打不开可能是因为防火墙端口没有开放
#开放80端口：
firewall-cmd --zone=public --add-port=80/tcp --permanent

#查询端口号80 是否开启：
firewall-cmd --query-port=80/tcp

#重启防火墙：（重启后生效）
firewall-cmd --reload

# 打开配置文件
vi /usr/local/nginx/conf/nginx.conf

#重启
/usr/local/nginx/sbin/nginx -s reload
