1.背景及描述

當(dāng)我使用systemctl start nginx.service或者service nginx start命令啟動nginx，發(fā)現(xiàn)啟動失敗.當(dāng)使用nginx -t卻顯示OK.查看狀態(tài)，信息如下：

情況1：

2.臨時解決方案

2.1 使用./nginx啟動

參考多篇博客均以失敗告終，最后偶然發(fā)現(xiàn)，如果通過安裝目錄下sbin中的nginx可以正常啟動.命令如下：

#進入nginx安裝目錄下的sbin目錄，并指定配置文件啟動
./nginx -c /etc/local/nginx/conf/nginx.conf

2.2 殺掉./nginx啟動的進程，再使用service方式啟動

也有博客是這樣說的

只是很多時候我們都先用/usr/local/nginx/sbin/nginx來啟動了nginx

只要找到這個進程kill掉以后,再執(zhí)行/etc/rc.d/init.d/nginx start就一切正常了

即：先kill掉./nginx啟動的進程，然后再換成service nginx start方式啟動

3.總結(jié)

如果符合如下狀態(tài)

• nginx -t顯示狀態(tài)ok

• systemctl start nginx.service或者service nginx start命令啟動nginx失敗

• 報錯信息為：nginx.service - SYSV: NGINX is an HTTP(S) server, HTTP(S) reverse proxy and IMAP/POP3 proxy server

• 報錯信息為：Process: 38258 ExecStart=/etc/rc.d/init.d/nginx start (code=exited, status=203/EXEC)

請嘗試：

• 更改為./nginx -c /etc/local/nginx/conf/nginx.conf方式啟動

• kill掉./nginx啟動的進程，然后再換成service nginx start方式啟動文章來源地址http://www.zghlxwxcb.cn/news/detail-456114.html
