Apache升级

一、前提

• 备份旧版httpd的配置，卸载旧版的httpd。

• 时间：2023-5-24 系统：Centos 7.6 默认版本：Apache 2.4.6

[root@habits ~]# httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   Apr  5 2023 17:18:30

• 这时候最新的apache版本是2.4.57

二、更新版本

• 查找Centos上软件库里的httpd版本:

[root@habits ~]# yum info httpd
Loaded plugins: fastestmirror, langpacks, product-id, search-disabled-repos, subscription-manager
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * centos-sclo-sclo: mirrors.bupt.edu.cn
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
Installed Packages

（显示默认软件库中只有2.4.6版本的apache）

• CodeIT库提供了最新版本的服务器软件(Apache & Nginx)。这个库依赖 epel 。
  先要安装 epel-release

[root@habits ~]# yum install -y epel-release

• 安装CodeIT库

[root@habits ~]# cd /etc/yum.repos.d && wget https://repo.codeit.guru/codeit.el7.repo `rpm -q --qf "%{VERSION}" $(rpm -q --whatprovides redhat-release)`.repo

# /etc/yum.repos.d目录下新增了文件: codeit.el7.repo 内容如下：
[CodeIT]
name=CodeIT repo
baseurl=https://repo.codeit.guru/packages/centos/7/$basearch
enabled=1
gpgkey=https://repo.codeit.guru/RPM-GPG-KEY-codeit
gpgcheck=1

• 再次查询可以安装的版本

[root@habits ~]# yum info httpd

 * base: mirrors.aliyun.com
 * centos-sclo-sclo: mirrors.bupt.edu.cn

（显示有2.4.57版本）

• 安装新的httpd

[root@habits ~]# yum -y install httpd
[root@habits ~]# systemctl start httpd && systemctl enable httpd
[root@habits ~]# httpd -v

三、排错

• 安装后不能运行（提示缺少libpcre2-8.so.0）

find / -name libpcre2-8.so.0                  # 找到文件的位置，我的系统中有这个文件，只是不能识别
cp   libpcre2-8.so.0  /usr/lib64/     # 复制到/usr/lib64/这个目录
systemctl restart httpd                       # 再次运行可以启动了
