nginx 启动报错 “varrunnginxnginx.pid failed” 解决方法

问题：

　　重启服务器后，再次重启nginx会报错： open() "/var/run/nginx/nginx.pid" failed (2: No such file or directory)

解决 nginx: [alert] kill(189, 1) failed (3: No such process)

[root@localhost/]# nginx -s reload

nginx: [alert] kill(189, 1) failed (3: No such process)  杀死189进程，可是并没有

[root@localhost /]# whereis ngnix

ngnix:[root@localhost/]# 

[root@localhost /]# find / -name nginx 

/usr/local/src/nginx/sbin/nginx

[root@localhost /]# find / -name nginx.conf

/usr/local/src/nginx/conf/nginx.conf

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

[root@localhost/]# nginx -s reload 

　Nginx启动提示找不到libpcre.so.1解决方法

启动nginx提示：error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory，意思是找不到libpcre.so.1这个模块，而导致启动失败。

[root@lee ~]# /usr/local/webserver/nginx/sbin/nginx nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

如果是32位系统

[root@lee ~]#  ln -s /usr/local/lib/libpcre.so.1 /lib

如果是64位系统

[root@lee ~]#  ln -s /usr/local/lib/libpcre.so.1 /lib64

然后在启动nginx就OK了

[root@lee ~]# /usr/local/webserver/nginx/sbin/nginx
