46次课（Nginx安装 、 默认虚拟主机、Nginx用户认证、Nginx域名重定向）

Nginx安装

进入/usr/local/src目录下

[root@100xuni1 ~]# cd /usr/local/src/         

下载Nginx安装包可以去nginx.org或者https://coding.net/u/aminglinux/p/resource/git/blob/master/README.md下载

[root@100xuni1 src]# wget http://124.205.69.170/files/51490000069A64B9/nginx.org/download/nginx-1.14.0.tar.gz                    ##wget下载

解压

[root@100xuni1 src]# tar zxf nginx-1.14.0.tar.gz      ##解压
[root@100xuni1 src]# cd nginx-1.14.0/                    ##解压完成后进入

编译

[root@100xuni1 nginx-1.14.0]#  ./configure --prefix=/usr/local/nginx       ##编译

make

[root@100xuni1 nginx-1.14.0]# make

make install

[root@100xuni1 nginx-1.14.0]# make install

nginx目录

[root@100xuni1 nginx-1.14.0]# ls /usr/local/nginx/       ##目录
conf  html  logs  sbin
[root@100xuni1 nginx-1.14.0]# ls /usr/local/nginx/conf/     ##配置文件目录
fastcgi.conf          fastcgi_params          koi-utf  mime.types          nginx.conf          scgi_params          uwsgi_params          win-utf
fastcgi.conf.default  fastcgi_params.default  koi-win  mime.types.default  nginx.conf.default  scgi_params.default  uwsgi_params.default
[root@100xuni1 nginx-1.14.0]# ls /usr/local/nginx/html/       ##样例文件
50x.html  index.html
[root@100xuni1 nginx-1.14.0]# ls /usr/local/nginx/logs/            ##存放日志
[root@100xuni1 nginx-1.14.0]# ls /usr/local/nginx/sbin/      ##他的进程核心的文件
nginx

-t也是支持的查询配置文件是否有错

[root@100xuni1 nginx-1.14.0]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

给nginx创建配置文件还要给他做个启动脚本

[root@100xuni1 nginx-1.14.0]# vim /etc/init.d/nginx       ##启动脚本存放位置，配置这个文件内容去https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/etc_init.d_nginx 把这里的内容拷贝到nginx里

改权限

[root@100xuni1 nginx-1.14.0]#  chmod 755 /etc/init.d/nginx

开机启动

[root@100xuni1 nginx-1.14.0]#  chkconfig --add nginx 
[root@100xuni1 nginx-1.14.0]# chkconfig nginx on 

编辑配置文件这个配置文件需要下载模板

[root@100xuni1 nginx-1.14.0]# cd /usr/local/nginx/conf/    ##进入配置文件
[root@100xuni1 conf]# ls          ##这个里边nginx.conf了不用他的用自己的，
fastcgi.conf          fastcgi_params          koi-utf  mime.types          nginx.conf          scgi_params          uwsgi_params          win-utf
fastcgi.conf.default  fastcgi_params.default  koi-win  mime.types.default  nginx.conf.default  scgi_params.default  uwsgi_params.default
[root@100xuni1 conf]# mv nginx.conf nginx.conf.1   ##拷贝改名字

开始配置

[root@100xuni1 conf]# vim nginx.conf     ##去https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/nginx.conf下拷贝内容
