yum报错, 说是伯克利的那个嵌入式数据库报错~ 重建一下就好了 cd /var/lib/rpm rm -rf __db* rpm --rebuilddb
升级一下内核
查了一下, 安装了一堆乱七八糟的
rpm -qa | grep kernel
留一个能用的,全删掉
yum remove -y kernel-xxxxxx
公司服务器不让上网, 那就手动来搞
原命令是这样的,
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm 只能先下载下来文件, scp上去, 手动执行一下
https://www.elrepo.org/RPM-GPG-KEY-elrepo.org http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm rpm --import RPM-GPG-KEY-elrepo.org 安装repo rpm -Uvh elrepo-release-7.0-3.el7.elrepo.noarch.rpm 然后,还是公司不让联网...好在公司自己有镜像网站, 赞一个, 自己编辑yum repo --------------------------------------------------------------------------------- ### Name: ELRepo.org Community Enterprise Linux Repository for el7 ### URL: http://elrepo.org/ [elrepo] name=ELRepo.org Community Enterprise Linux Repository - el7 baseurl=http://mirrors.xxxxxxx/elrepo/elrepo/el7/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-elrepo.org protect=0 [elrepo-testing] name=ELRepo.org Community Enterprise Linux Testing Repository - el7 baseurl=http://mirrors.xxxxxxx/elrepo/testing/el7/$basearch/ enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-elrepo.org protect=0 [elrepo-kernel] name=ELRepo.org Community Enterprise Linux Kernel Repository - el7 baseurl=http://mirrors.xxxxxxx/elrepo/kernel/el7/$basearch/ enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-elrepo.org protect=0 [elrepo-extras] name=ELRepo.org Community Enterprise Linux Extras Repository - el7 baseurl=http://mirrors.xxxxxxx/elrepo/extras/el7/$basearch/ enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-elrepo.org protect=0 --------------------------------------------------------------------------------- 看一下,哪个有效 yum --disablerepo="*" --enablerepo="elrepo-kernel" list available 安装个稳定版本吧: yum --enablerepo=elrepo-kernel install kernel-ml 安装完 init 6 grub菜单, 选上新内核, 进去, 再次删除不需要的内核,~~~OK ---------------------------------------------------------------------------------- repo 官网 http://elrepo.org/tiki/tiki-index.php 外国人写的: https://www.tecmint.com/install-upgrade-kernel-version-in-centos-7/
20200102 升级内核5.4.7
vim /boot/grub2/grub.cfg
20200604 升级内核5.7.0-1.el7.elrepo.x86_64
------------------------------------------------------
升级gcc
https://medium.com/@bipul.k.kuri/install-latest-gcc-on-centos-linux-release-7-6-a704a11d943d
http://gnu.mirror.iweb.com/gcc/gcc-8.4.0/ tar -zxvf xxx.tar.gz mkdir gcc-build cd gcc-build ../configure --enable-languages=c,c++ --disable-multilib make -j4 make install
这老兄写得不错哟~~~
#!/bin/sh GCC_VERSION=9.2.0 sudo yum -y update sudo yum -y install bzip2 wget gcc gcc-c++ gmp-devel mpfr-devel libmpc-devel make gcc --version wget http://gnu.mirror.constant.com/gcc/gcc-$GCC_VERSION/gcc-$GCC_VERSION.tar.gz tar zxf gcc-$GCC_VERSION.tar.gz mkdir gcc-build cd gcc-build ../gcc-$GCC_VERSION/configure --enable-languages=c,c++ --disable-multilib make -j$(nproc) sudo make install gcc --version cd .. rm -rf gcc-build
还算不错, 看网上有人build了2个多小时, 我这里一个小时.
[root@xxxxxxx]# gcc --version

主要是最后要把软连接删掉重建, 文件夹比较坑, 因为是make的时候prefix指定的
另外一种方式, 比较好, 使用yum安装
