yum install -y nginx

通过yum安装的时候提示下面的错误

[root@localhost yum.repos.d]# yum install nginx

已加载插件:fastestmirror, langpacks

Loading mirror speeds from cached hostfile

没有可用软件包 nginx。

错误:无须任何处理

需要添加nginx的源

[root@localhost yum.repos.d]# rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

该命令执行之后,会在/etc/yum.respos.d下面多出一个nginx.repo

[root@localhost yum.repos.d]# ll

总用量 40

-rw-r–r–. 1 root root 1572 12月  1 2016 CentOS-Base.repo

-rw-r–r–. 1 root root 1572 12月  1 2016 CentOS-Base.repo.backup

-rw-r–r–. 1 root root 1664 10月 24 10:36 CentOS-Base.repo.bak

-rw-r–r–. 1 root root  314 8月  30 2017 CentOS-fasttrack.repo

-rw-r–r–. 1 root root  630 8月  30 2017 CentOS-Media.repo

-rw-r–r–. 1 root root 1331 8月  30 2017 CentOS-Sources.repo

-rw-r–r–. 1 root root 3830 8月  30 2017 CentOS-Vault.repo

-rw-r–r–. 1 root root  113 7月  15 2014 nginx.repo

然后再执行安装命令

yum install -y nginx

安装之后,可以查看nginx的默认安装目录

[root@localhost yum.repos.d]# whereis nginx

nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz

[root@localhost yum.repos.d]# pwd

/etc/yum.repos.d

以下是Nginx的默认路径:

(1) Nginx配置路径:/etc/nginx/

(2) PID目录:/var/run/nginx.pid

(3) 错误日志:/var/log/nginx/error.log

(4) 访问日志:/var/log/nginx/access.log

(5) 默认站点目录:/usr/share/nginx/html

事实上,只需知道Nginx配置路径,其他路径均可在/etc/nginx/nginx.conf 以及/etc/nginx/conf.d/default.conf 中查询到

nginx相关的验证命令及启动命令

[root@localhost yum.repos.d]# nginx                    

[root@localhost yum.repos.d]# nginx -t                   

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

[root@localhost yum.repos.d]# nginx -s reload             

nginx   启动

nginx -t  测试命令

nginx -s relaod 修改nginx.conf之后,可以重载
