1.啟動(dòng)

/usr/local/nginx/sbin/nginx

2.重啟

/usr/local/nginx/sbin/nginx -s reload

3.關(guān)閉

/usr/local/nginx/sbin/nginx -s stop

4.檢驗(yàn)配置文件

/usr/local/nginx/sbin/nginx -t

5.再啟動(dòng)nginx服務(wù)時(shí)，無(wú)法正常啟動(dòng)，報(bào)錯(cuò)誤信息如下

[root@localhost nginx]# /usr/local/nginx/sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful[root@localhost nginx]# /usr/local/nginx/sbin/nginx -s reload nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"

-t 沒(méi)問(wèn)題，reload就報(bào)錯(cuò)了。因?yàn)槭羌虞d配置文件報(bào)的錯(cuò)，所以用-c 選項(xiàng)指定配置文件 ，如此指明后問(wèn)題解決搜了一下解決：

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

6.此時(shí)如果nginx進(jìn)程殺死后pid丟失了，下一次再開(kāi)啟nginx -s reload時(shí)無(wú)法啟動(dòng)，重裝可以解決這個(gè)問(wèn)題，但是太麻煩了，也可以用

[root@localhost logs]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/logs/nginx.pid

注：看是不是端口被占用

ss -nulpt

7.記錄我的一個(gè)報(bào)錯(cuò)

1.先用網(wǎng)上查的方法測(cè)了

[root@localhost logs]# /usr/local/nginx/sbin/nginx -s reload
nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)

[root@localhost logs]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/logs/nginx.pid
nginx: [emerg] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)

2.查看是否啟動(dòng)

[root@localhost logs]# ss -nulpt? | grep :80
tcp??? LISTEN???? 0????? 128?????????????????????? *:80??????????????????????????????????? *:*?????????????????? users:(("nginx",pid=4488,fd=6),("nginx",pid=4487,fd=6))

[root@localhost logs]#? pgrep nginx
4487
4488

3.嘗試手動(dòng)關(guān)閉

[root@localhost nginx]# /usr/local/nginx/sbin/nginx -s stop
nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)

[root@localhost logs]#? killall -9 nginx

[root@localhost logs]#? ps -auxf | grep nginx
root????? 4518? 0.0? 0.0 112720?? 984 pts/1??? S+?? 21:28?? 0:00????????? \_ grep --color=auto nginx

4.重啟就好啦

[root@localhost logs]#? /usr/local/nginx/sbin/nginx

[root@localhost logs]# ss -nulpt | grep nginx
tcp??? LISTEN???? 0????? 128?????? *:80??????????????????? *:*?????????????????? users:(("nginx",pid=4521,fd=6),("nginx",pid=4520,fd=6))

[root@localhost logs]# ls
access.log? error.log? nginx.pid

一開(kāi)始百度解決該問(wèn)題。只是找到幾個(gè)求助答案。沒(méi)有實(shí)際有效的方法，搜到的也是-c的那個(gè)

總結(jié)

以上是生活随笔為你收集整理的nginx（No such file or directory与invalid PID number）的全部?jī)?nèi)容，希望文章能夠幫你解決所遇到的問(wèn)題。
