2025-1-9

大家好，如果您还对centos json 安装不太了解，没有关系，今天就由本站为大家分享centos json 安装的知识，包括centos7.0下载的问题都会给大家分析到，还望可以解决大家的问题，下面我们就开始吧！

centos8安装tcmalloc

做存储,数据库系统方面的开发，主要用到* grpc/libevent/libev/libasio实现高性能网络服务器* protobuf数据结构序列化/反序列化，方便数据交换* LevelDB/RocksDB嵌入式KV数据库* snappy/zlib/lz4数据压缩，解压缩* jemalloc/tcmalloc高效内存分配器，尤其多线程场景* jerasure Reed Solomon编解码，给存储系统实现erasure code* murmurhash…实现hash摘要* crc32数据存储或传输时的数据校验* cJSON解析json格式配置文件* libBSON JSON序列化/反序列化，MongoDB使用这种格式存储数据* boost功能丰富的C++基础库，轻度使用，C++11/14后基本不用了。* libRedis redis是一个数据库服务，并不是单独的库，但其代码精简，质量非常高，里面很多代码都可以拿出来直接复用，比如网络，各种数据结构的实现。

centos无法从extensions.gnome.org下载更新,怎么办

问题现象：刚安装好的CentOS 8使用GNOME软件来更新时出现问题，不能更新下载。

问题分析：初步分析是原系统下载源被和谐或者是下载速度过慢的原因。

解决办法：查找网上教程，通过将下载源更换为国内yum下载源恢复下载，操作如下：

1.备份现有源

mv/etc/yum.repos.d/etc/yum.repos.d.backup

2.设置新的yum目录

mkdir/etc/yum.repos.d

3.安装wget

yum install-y wget

4.下载配置。此处一定要注意，很多教程都是CentOS 7的教程，所以贴的CentOS 7的下载源，对于CentOS 8一定要改为CentOS 8的下载源，否则还是不行。

wget-O/etc/yum.repos.d/CentOS-Base.repo

5.清除文件并重建元数据缓存

yum clean all

yum makecache

6.最后更新软件包，稍等软件安装包安装完就可以了

yum update-y

阿里云上的centos 7.2怎么yum安装php 5.6

因之前通过网易的 centos镜像，将阿里云的 centos升级到最新版了，乘自己的项目尚未开始正式开发，遂将所有的相应环境都升级到最高。

查看 centos版本：

[root@iZ23d~]# cat/etc/centos-release

CentOS Linux release 7.2.1511(Core)

1、删除之前的 php版本：

[root@iZ23d~]# yum remove php* php-common

Loaded plugins: langpacks

Repository base is listed more than once in the configuration

Repository updates is listed more than once in the configuration

Repository extras is listed more than once in the configuration

Repository centosplus is listed more than once in the configuration

No Match for argument: php-5.4.16

No Match for argument: php-5.4.16.tar.gz

No Match for argument: php-7.0.1RC1

No Match for argument: php-7.0.1RC1.tar.gz

No Match for argument: phpMyAdmin-4.4.0.tar.gz

No Match for argument: php-common

No Packages marked for removal

2、rpm安装 Php7相应的 yum源：

[root@iZ23d~]# rpm-Uvh

package webtatic-release-7-3.noarch is already installed

3、直接yum安装php7：

[root@iZ23d~]# yum install php70w

Loaded plugins: langpacks

Repository base is listed more than once in the configuration

Repository updates is listed more than once in the configuration

Repository extras is listed more than once in the configuration

Repository centosplus is listed more than once in the configuration

Complete!

4、检查 php版本：

[root@iZ23d~]# php-v

PHP 7.0.0(cli)(built: Dec 2 2015 20:42:32)( NTS)

[root@iZ23d2e6hoqZ~]#

以上显示安装成功！

5、重启 Apache，查看 phpinfo:

[root@iZ23d~]# systemctl restart httpd.service

检查phpinfo:
