一、报版本过低问题

问题：

error: Failed dependencies:
libcrypto.so.1.1()(64bit) is needed by erlang-25.1.2-1.el8.x86_64
libcrypto.so.1.1(OPENSSL_1_1_0)(64bit) is needed by erlang-25.1.2-1.el8.x86_64

解决方式一：

• 在该命令后面加上 --nodeps --force
• 该命令的作用： 不再分析包之间的依赖关系而直接安装

rpm -ivh erlang-25.1.2-1.el8.x86_64.rpm  --nodeps --force

解决方式二：

说明gblic 版本太低。我们可以查看当前机器的gblic 版本

strings /lib64/libc.so.6 | grep GLIBC

当前最高版本2.17，需要*.所以需要升级glibc

1. 使用yum更新安装依赖

sudo yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y

2. 下载rpm包

wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-utils-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-static-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-common-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-devel-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-headers-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/nscd-2.17-55.el6.x86_64.rpm &

又出现一个问题：

-bash: wget: command not found

CentOS系统:

yum install wget -y

Debian/Ubuntu系统，需要执行以下命令：

apt-get install -y wget

再次执行上面的rpm包

wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-utils-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-static-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-common-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-devel-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-headers-2.17-55.el6.x86_64.rpm &
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/nscd-2.17-55.el6.x86_64.rpm &

3. 安装rpm包

sudo rpm -Uvh *-2.17-55.el6.x86_64.rpm --force --nodeps

4. 安装完毕后再查看glibc版本,发现glibc版本已经到2.17了

strings /lib64/libc.so.6 | grep GLIBC
