apache安装

环境：centos6.5
生产环境最好源码编译安装Apache，可灵活定制各种功能、及时获取软件的最新版本以及便于今后在不同的系统之间移植。

yum安装apache

1、检查是否安装apache

[root@h1 ~]# rpm -qa | grep httpd
httpd-tools-2.2.15-29.el6.centos.x86_64
httpd-2.2.15-29.el6.centos.x86_64

2、卸载自带默认apache，并再次检查

[root@h1 ~]# rpm -e --nodeps httpd-tools-2.2.15-29.el6.centos.x86_64
[root@h1 ~]# rpm -e --nodeps httpd-2.2.15-29.el6.centos.x86_64
[root@h1 ~]# rpm -qa | grep httpd
[root@h1 ~]# 

或者yum卸载

[root@h1 ~]# yum remove httpd* -y

3、yum安装

[root@h1 ~]# yum install httpd -y
[root@h1 ~]# rpm -qa | grep httpd
httpd-tools-2.2.15-60.el6.centos.6.x86_64
httpd-2.2.15-60.el6.centos.6.x86_64

4、启动apache服务

[root@h1 ~]# /etc/init.d/httpd start
正在启动 httpd：httpd: apr_sockaddr_info_get() failed for h1
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

这个报错需要更改配置文件

[root@h1 init.d]# vi /etc/httpd/conf/httpd.conf

取消276行servername注释即可

#
ServerName www.example.com:80

这个报错说明80端口一直被占用，

(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
                                                           [失败]

找到占用80端口的进程

[root@h1 init.d]# netstat -lnp|grep 80
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      9855/nginx          
tcp        0      0 :::54980                    :::*                        LISTEN      1591/rpc.statd      
unix  2      [ ACC ]     STREAM     LISTENING     19380  2397/evolution-alar /tmp/orbit-root/linc-95d-0-35b0575818c16

是因为以前测试nginx占用了80端口，杀掉占用80端口的pid进程，或者更改默认端口

[root@h1 init.d]# kill 9855
[root@h1 init.d]# netstat -lnp|grep 80
tcp        0      0 :::54980                    :::*                        LISTEN      1591/rpc.statd      
unix  2      [ ACC ]     STREAM     LISTENING     19380  2397/evolution-alar /tmp/orbit-root/linc-95d-0-35b0575818c16
[root@h1 init.d]#

重启成功

[root@h1 init.d]# /etc/init.d/httpd restart
停止 httpd：                                               [确定]
正在启动 httpd：                                           [确定]
