Tuesday, April 2nd 2019, 7:16:11 am ( ISO 8601 )
Linux 服务器有的初始化软件版本过低,经常面临软件更新、安全问题,我们该如何更新软件呢?
-
备份 CentOS-Base.repo
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
-
下载新的CentOS-Base.repo 到 /etc/yum.repos.d/
# centos 5 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo # centos 6 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo # centos 7 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
-
# 把服务器的包信息下载到本地电脑缓存起来 yum makecache yum install epel-release yum install nginx
-
把Nginx从1.12.2升级到 1.14.2
-
为yum建立nginx安装库
# 在/etc/yum.repos.d目录下创建文件nginx.repo,输入如下内容: # nginx.repo [nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/7/$basearch/ gpgcheck=0 enabled=1
-
升级Nginx
# 运行 > yum update nginx # ok 了 # 停止、重启nginx服务: > service nginx stop Stopping nginx: [ OK ] > service nginx start Starting nginx: [ OK ]
-
清理 nginx repo
# 再次编辑文件/etc/yum.repos.d/nginx.repo: # nginx.repo [nginx] # 其他内容省略 enabled=0 # 最后,清理yum的缓存: > yum clean all
