一、備份原始httpd配置文件

**主要是httpd.conf文件，如果conf.d目錄下有配置文件也需要備份**
[root@loaclhost ~]# httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   May 30 2023 14:01:11
[root@loaclhost ~]# mkdir apache_bak
[root@loaclhost ~]# cd /etc/httpd/conf
[root@loaclhost conf]# cp httpd.conf /root/apache_bak/

二、停止并卸載原始httpd服務(wù)

我這邊是yum（rpm）安裝的

[root@loaclhost conf]# systemctl stop httpd
[root@loaclhost conf]# rpm -qa | grep http
httpd-tools-2.4.6-99.el7.centos.1.x86_64
httpd-2.4.6-99.el7.centos.1.x86_64
[root@loaclhost conf]# 
[root@loaclhost conf]# rpm -e `rpm -qa | grep http`
warning: /etc/httpd/conf/httpd.conf saved as /etc/httpd/conf/httpd.conf.rpmsave
[root@loaclhost conf]# 

三、上傳新版httpd安裝包并安裝

[root@loaclhost ~]# ll httpd_2.4.57_rpm_all.tar.gz 
-rw-r--r-- 1 root root 9992002 Jan 15 17:13 httpd_2.4.57_rpm_all.tar.gz
[root@loaclhost ~]# tar -xf httpd_2.4.57_rpm_all.tar.gz 
[root@loaclhost ~]# 
[root@loaclhost ~]# cd httpd_2.4.57
[root@loaclhost httpd_2.4.57]# 
[root@loaclhost httpd_2.4.57]# ll
total 10020
-rw-r--r-- 1 root root 1426560 Jul 27  2023 httpd-2.4.57-1.x86_64.rpm
-rw-r--r-- 1 root root 3889892 Jul 27  2023 httpd-debuginfo-2.4.57-1.x86_64.rpm

[root@loaclhost httpd_2.4.57]# rpm -ivh *.rpm --nodeps

[root@loaclhost httpd_2.4.57]#

四、先啟動httpd，查看版本

這邊已升級到2.4.57版本

[root@loaclhost httpd_2.4.57]# systemctl start httpd
[root@loaclhost httpd_2.4.57]# 
[root@loaclhost httpd_2.4.57]# httpd -v
Server version: Apache/2.4.57 (Unix)
Server built:   Jul 27 2023 16:50:18
[root@loaclhost httpd_2.4.57]#

五、還原配置文件

建議先把新版httpd的http.conf文件備份一下，防止版本差異配置文件不一樣導(dǎo)致無法啟動

[root@loaclhost conf]# cp httpd.conf httpd.conf.bak
[root@loaclhost conf]# rm -rf httpd.conf
[root@loaclhost conf]# cp /root/apache_bak/httpd.conf .
[root@loaclhost conf]# systemctl restart httpd
