lnmt部署流程

• 在192.168.225.128上安装nginx

//创建系统用户nginx
[root@hxdserver ~]# groupadd -r nginx
[root@hxdserver ~]# useradd -r -M -s /sbin/nologin nginx -g nginx
//安装依赖环境
[root@hxdserver ~]# yum -y install pcre-devel openssl openssl-devel gd-devel gcc gcc-c++
[root@hxdserver ~]# yum -y groups install 'Development Tools'

//创建日志存放目录
[root@hxdserver ~]# mkdir -p /var/log/nginx
[root@hxdserver ~]# chown -R nginx.nginx /var/log/nginx/
//下载nginx
[root@hxdserver ~]# cd /usr/src/
[root@hxdserver src]# wget http://nginx.org/download/nginx-1.14.0.tar.gz --2018-08-20 11:19:09--  http://nginx.org/download/nginx-1.14.0.tar.gz
[root@hxdserver src]# ls

//编译安装
[root@hxdserver src]# tar xf nginx-1.14.0.tar.gz 
[root@hxdserver nginx-1.14.0]# cd nginx-1.14.0/
[root@hxdserver nginx-1.14.0]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-debug --with-http_ssl_module --with-http_realip_module --with-http_image_filter_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_stub_status_module --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log
[root@hxdserver nginx-1.14.0]# make && make install

//nginx安装后配置
//设置环境变量
[root@hxdserver ~]# echo 'export PATH=/usr/local/nginx/sbin:$PATH' > /etc/profile.d/nginx.sh
[root@hxdserver ~]# . /etc/profile.d/nginx.sh
//启动nginx
[root@hxdserver ~]# nginx 
[root@hxdserver ~]# ss -antl

//关闭防火墙
[root@hxdserver ~]# systemctl stop firewalld.service
//关闭selinux
[root@hxdserver ~]# setenforce 0
