Apache启动报错Address already in use: make_sock: could not bind to...

Apache启动时报错：(98)Address already in use: make_sock: could not bind to...

# /etc/init.d/httpd start
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
[FAILED]

1.查找占用80端口的进程，检查该进程是否能停用。结果为PID为846

#netstat -lnp|grep 80 或[ps -ef|grep 80]

tcp 0 0 192.168.180.68:61027 0.0.0.0:* LISTEN 6289/oproxyd
tcp 0 0 :::80 :::* LISTEN 846/httpd
tcp 0 0 ::ffff:192.168.180.68:7001 :::* LISTEN 32015/java

2.杀掉进程

#kill -9 846

3.启动成功

#./apachectl start

Starting httpd: [ OK ]

**********************************************************

用到知识点：

1.ps -ef|grep <端口>/<进程名>：按名称或端口查找进程的PID 

2.kill -9 <PID>：使用kill杀死进程，参数为PID
