nginx – 东风吹

https网站中终于可以解析php文件了

搁置了几天时间，今天闲来把502的问题解决一下，在amh界面中重新创建一个空间，然后ssl也配置上，然后把阿里云盾打包下载的pem文件用记事本打开，复制、粘贴进SSL配置文件里（如下图）

ssl

在# vi /usr/local/nginx/conf/vhost/game.adongblog.com.conf(这里是你在amh界面中配置出来空间后自动创建的)，把这里调整一下：

#------SSL BEGIN
listen 443;
ssl on;
ssl_certificate /usr/local/nginx/conf/ssl/game.adongblog.com.pem; 
#AMH界面创建好后，上面这一行他指定的是.crt的文件，把他修改过来。
ssl_certificate_key /usr/local/nginx/conf/ssl/game.adongblog.com.key;
#上面这一行他默认指定的是pem的文件，在阿里云盾创建的证书打包下载的key为这个，把他修改为.key的后缀。
#------SSL END

#------SSL BEGIN

listen 443;

ssl on;

ssl_certificate /usr/local/nginx/conf/ssl/game.adongblog.com.pem;

#AMH界面创建好后，上面这一行他指定的是.crt的文件，把他修改过来。

ssl_certificate_key /usr/local/nginx/conf/ssl/game.adongblog.com.key;

#上面这一行他默认指定的是pem的文件，在阿里云盾创建的证书打包下载的key为这个，把他修改为.key的后缀。

#------SSL END

最后上传一个<?php phpinfo(); ?>文件测试，可以正常打开了。。。

nginx中无法解析php文件的问题

高兴的太早，可以正常访问还是http下的，而在https下还是不能正常解析php文件，还是显示 502 Bad Gateway

nginx 启动时端口占用的问题

因为安装好apache后，设置了端口，于是重启nginx时出现以下的提示：

[root@iZwz9bycr7k0ldi7hent6oZ sbin]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

配置https后一直显示welcome to nginx!的问题

这个问题折磨了我一两天了，就是nginx.conf配置的问题中路径设置的问题。

nginx: [error] invalid PID number “” in “/var/run/nginx.pid”

输入以下两条命令：

# sudo nginx -c /usr/local/etc/nginx/nginx.conf
# sudo nginx -s reload

如何查找nginx的安装目录和相关操作

Linux环境下，怎么确定Nginx是以那个config文件启动的？
[root@localhost ~]# ps -ef | grep nginx
root 21196 1 0 23:40 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
nginx 21197 21196 0 23:40 ? 00:00:00 nginx: worker process
root 21199 20993 0 23:42 pts/0 00:00:00 grep –color=auto nginx
————————————
检查是否已经安装有nginx及对应目录：
[root@localhost ~]# find /|grep nginx.conf
/etc/nginx/conf.d
/etc/nginx/conf.d/example_ssl.conf
/etc/nginx/conf.d/default.conf
/etc/nginx/nginx.conf

nginx1 ———————————-
还可以用以下两个命令，找安装的路径
[root@localhost ~]# netstat -tnlp|grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 21196/nginx: master
然后看到一行记录，复制最后的一个数据（进程ID）
ps -aux |grep 进程ID
就可以看到nginx的启动方式了。
[root@localhost ~]# ps -aux |grep 21196
root 21196 0.0 0.0 48044 924 ? Ss 23:40 0:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
root 21204 0.0 0.2 112648 2320 pts/0 S+ 23:45 0:00 grep –color=auto 21196

——————————–
查看服务器上安装的nginx版本号，主要是通过ngix的-v或-V选项
Linux下查看Nginx安装目录、版本号信息?
-v 显示 nginx 的版本。
-V 显示 nginx 的版本，编译器版本和配置参数。
[root@localhost ~]# /usr/sbin/nginx -v
nginx version: nginx/1.8.0

===================================
查看linux系统版本命令
[root@localhost ~]# cat /proc/version
Linux version 4.1.5-x86_64-linode61 (maker@build) (gcc version 4.7.2 (Debian 4.7.2-5) ) #7 SMP Mon Aug 24 13:46:31 EDT 2015
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.0.1406 (Core)

===================================
Ubuntu下安装nginx，直接apt-get install nginx就行了

CentOS 下安装nginx：
centos7系统库中默认是没有nginx的rpm包的，所以我们自己需要先更新下rpm依赖库
(1)使用yum安装nginx需要包括Nginx的库，安装Nginx的库
rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
rpm包的安装：
1.安装一个包
# rpm -ivh
2.升级一个包，没安装过的不能使用升级命令
# rpm -Uvh
3.移走一个包
# rpm -e

安装准备依赖lib库
yum install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

(2)使用下面命令安装nginx
#yum install nginx

(3)启动Nginx
#service nginx start
或
#systemctl start nginx.service
(4)重启nginx
service nginx restart
