使用 service nginx start 启动报错:
nginx.service – SYSV: Nginx is a high-performance web and proxy server.
但是直接运行安装目录下的 sbin/nginx 文件可以成功。
systemctl status nginx.service 查看后,详细如下:
nginx.service – SYSV: Nginx is a high-performance web and proxy server.
Loaded: loaded (/etc/rc.d/init.d/nginx; bad; vendor preset: disabled)
Active: failed (Result: exit-code) since Tue 2017-03-21 11:29:22 CST; 52s ago
Docs: man:systemd-sysv-generator(8)…
nginx.service: control process exited, code=exited status=1
Failed to start SYSV: Nginx is a high-performance web and proxy server..
Unit nginx.service entered failed state.
nginx.service failed.
可能原因：提示已经存在相关进程，系统中存在未杀死的nginx进程。
解决方案 , 先杀掉所有nginx进程再启动:
killall nginx
service nginx start
