nginx(一)安装与命令总结

不同平台上安装nginx

1.mac 安装在命令行中输入以下命令，前提安装好brew

brew install nginx

2.Linux centos安装linux

先需要安装源：

rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm

yum install nginx

启动nginx

service nginx start

常用命令总结：

nginx -t;//检查配置文件nginx.conf是否正确
nginx -s reload;//重载配置
nginx -c /etc/nginx/nginx.conf;//启动nginx
ps -ef|grep nginx;//查看nginx进程
service nginx start;//启动nginx
service nginx stop;//关闭nginx

常见问题解决方案

1.很多时候我们nginx -s reload 会出现 nginx: [error] invalid PID number "" in "/var/run/nginx.pid"

原因是：nginx -s reload is only used to tell a running nginx process to reload its config. After a stop, you don't have a running nginx process to send a signal to. Just run nginx (possibly with a -c /path/to/config/file)

可通过下面命令来启动nginx

nginx -c /etc/nginx/nginx.conf

2.运行service nginx start 启动nginx出现Starting nginx: nginx: [emerg] open() "/var/run/nginx.pid" failed (13: Permission denied) 是因为权限的设置问题导致

可通过下面命令来启动nginx

nginx -c /etc/nginx/nginx.conf

3. 启动nginx 有可能出现下面的错误 Starting nginx: nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)解决方案修改/etc/nginx/conf.d/default.conf为删除listen [::]:80 default_server;

listen 80;
listen [::]:80 default_server;

修改之后的结果为

listen       80;
server_name  _;

通过下面命令查看nginx服务是否启动

ps -ef|grep nginx

看到下面的信息说明nginx安装成功了

[root@VM_30_103_centos etc]# ps -ef|grep nginx
root      3294     1  0 Jun21 ?        00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
root     27118  3294  1 13:57 ?        00:00:00 nginx: worker process                   
root     27119  3294  0 13:57 ?        00:00:00 nginx: worker process                   
root     27120  3294  1 13:57 ?        00:00:00 nginx: worker process                   
root     27121  3294  0 13:57 ?        00:00:00 nginx: worker process                   
root     27123 26467  0 13:57 pts/0    00:00:00 grep nginx

下面就开启学习nginx之旅吧!
