centos 5.6 yum(centos现在哪个版本最流行)

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

3、直接yum安装php7：

[root@iZ23d~]# yum install php70w

4、检查 php版本：

[root@iZ23d~]# php-v

[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:

如何升级CentOS 6.5下的MySQL

CentOS 6.5自带安装了MySQL 5.1，但5.1有诸多限制，而实际开发中，我们也已经使用MySQL 5.6，这导致部分脚本在MySQL 5.1中执行会出错。我们只能升级MySQL

方法/步骤

备份数据库，升级MySQL通常不会丢失数据，但保险起见，我们需要做这一步。输入命令：

mysqldump-uxxx-hxxx-P3306-p--all-databases>databases.sql

停止MySQL服务，输入命令：

servicemysqldstop

卸载旧版MySQL，输入命令：

yumremovemysqlmysql-*

执行过程中会询问你是否移除，此时输入“Y”

移除命令执行后，可再看看是否有残余的mysql，输入命令：

yumlistinstalled|grepmysql

如果有，可输入命令删除：

rumremovemysql－libs

下载安装最新的rpm文件

rpm-Uvh

安装MySQL，输入命令：

yuminstallmysql-community-server

安装完成后，输入命令查看MySQL版本号：

mysql-V

启动MySQL，输入命令：

servicemysqldstart

Centos7安装mysql缺乏yum源怎么安装

我首先想到的是安装VMware Tools，安装成功后，配置好共享文件夹后，总是报这个错

无奈，只好另寻他法。

随后又想到了，做个iso镜像，然后挂载在CDrom上，然后安装JDK成功，但是mysql安装失败，可能由于只从官网上下载了server，而没有解决依赖关系。

最后，找到mysql5.6的centos的repo源，终于解决mysql的安装问题：

1.确保centos安装了wget，没有的话安装wgetyuminstallwget

2.下载mysql的repo源

1：wget

2：安装mysql-community-release-el7-5.noarch.rpm包

3：rpm-ivh mysql-community-release-el7-5.noarch.rpm

4.安装这个包后，会获得两个mysql的yum repo源

[root@localhost

~]# ls-1/etc/yum.repos.d/mysql-community*

/etc/yum.repos.d/mysql-community.repo

/etc/yum.repos.d/mysql-community-source.repo

[root@localhost

~]#

5.然后安装mysql

yuminstallmysql-server

根据步骤安装就可以了，不过安装完成后，没有密码，需要充值密码：

mysql_secure_installation

可以根据这个命令，重置密码。也可以登录mysql再重置

mysql-u root

根据mysql的命令行来更改：

mysql> use

mysql;

mysql> update

usersetpassword=PASSWORD("GIVE-NEW-ROOT-PASSWORD")

where User='root';

mysql> flush

privileges;

mysql> quit
