本文实例讲述了Centos7.4服务器安装apache及安装过程出现的问题解决方法。分享给大家供大家参考，具体如下： 一、安装httpd 1. 安装之前，先查看系统中是否存在已经安装了的httpd.rpm包，如果，没有就是没安装，有的话rpm -e 对应的rpm包名进行删除 #rpm -qa | grep httpd 2. 使用yum安装(自动安装依赖包),简单方便 ? 1 #yum -y install httpd 3. 安装成功后，httpd-v 查看安装的apache版本，查找apache的配置文件位置 #find / -name "httpd.conf" 4. 将找到的源配置文件备份一份，防止错误后无法恢复 #cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.bak 5. 启动Apache服务 #systemctl start httpd.service 6. 开机自动启动Apache服务 #systemctl enable httpd.service 开机自启httpd #systemctl disable httpd.service 开机不启动httpd 7. 查看httpd的状态 #systemctl status httpd.service 二、安装过程出现的问题 1. Apache启动失败，Job for httpd.service failed because the control process exited with error code. See “systemctl status httpd.service” and “journalctl -xe” for details 执行命令,查看报错提示 #systemctl status httpd.service [root@cloud1 bin]# systemctl status httpd.service httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since 五 2018-11-26 11:13:09 CST; 6min ago Docs: man:httpd(8) man:apachectl(8) Process: 9915 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=1/FAILURE) Process: 9913 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE) Main PID: 9913 (code=exited, status=1/FAILURE) 11月 26 11:13:09 cloud1.localdomain httpd[9913]: (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80 11月 26 11:13:09 cloud1.localdomain httpd[9913]: (98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80 11月 26 11:13:09 cloud1.localdomain httpd[9913]: no listening sockets available, shutting down 11月 26 11:13:09 cloud1.localdomain httpd[9913]: AH00015: Unable to open logs 11月 26 11:13:09 cloud1.localdomain systemd[1]: httpd.service: main process exited, code=exited, status=1/FAILURE 11月 26 11:13:09 cloud1.localdomain kill[9915]: kill: cannot find process "" 11月 26 11:13:09 cloud1.localdomain systemd[1]: httpd.service: control process exited, code=exited status=1 11月 26 11:13:09 cloud1.localdomain systemd[1]: Failed to start The Apache HTTP Server. 11月 26 11:13:09 cloud1.localdomain systemd[1]: Unit httpd.service entered failed state. 11月 26 11:13:09 cloud1.localdomain systemd[1]: httpd.service failed. 问题是80端口被占用 解决办法： 查看80端口的使用情况 ① .netstat -lnp|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 杀掉占用80端口的进程 ② .kill -9 846 ③ .若是前两个方法不行的话，则重启后再启动httpd服务 2.Apache启动失败，httpd：httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName ① .进入apache的配置文件 vi /etc/httpd/conf/httpd.conf ② ./ServerName 查找ServerName #ServerName www.example.com:80 将其前面的#去掉 :wq保存并退出 ③ .重启服务 systemctl restart httpd.service (责任编辑：IT) |
