nginx(一)安裝與命令總結

不同平臺上安裝nginx

1.mac 安裝在命令行中輸入以下命令，?前提安裝好brew

brew install nginx

2.Linux centos安裝linux

先需要安裝源：

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

?

啟動nginx

service nginx start

?

常用命令總結：

nginx -t;//檢查配置文件nginx.conf是否正確 nginx -s reload;//重載配置 nginx -c /etc/nginx/nginx.conf;//啟動nginx ps -ef|grep nginx;//查看nginx進程 service nginx start;//啟動nginx service nginx stop;//關閉nginx

?

常見問題解決方案

1.很多時候我們nginx -s reload 會出現?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)

可通過下面命令來啟動nginx

nginx -c /etc/nginx/nginx.conf

2.運行service nginx start 啟動nginx出現Starting nginx: nginx: [emerg] open() "/var/run/nginx.pid" failed (13: Permission denied) 是因為權限的設置問題導致

可通過下面命令來啟動nginx

nginx -c /etc/nginx/nginx.conf

?

3.??啟動nginx 有可能出現下面的錯誤 Starting nginx: nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)解決方案修改/etc/nginx/conf.d/default.conf為 刪除listen [::]:80 default_server;

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

修改之后的結果為

listen 80; server_name _;

?

?

通過下面命令查看nginx服務是否啟動

ps -ef|grep nginx

?

看到下面的信息說明nginx安裝成功了

[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
