centos yum安装高版本php,apache,mysql

1.检查当前安装的PHP包

yum list installed | grep php 或者   yum list installed php*

如果要删除，可执行

yum remove php.x86_64 php-cli.x86_64

2.rpm包

CentOs 6.x
rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm

CentOs 7.X
rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

如果想删除上面安装的包，重新安装
rpm -qa | grep webtatic
rpm -e  上面搜索到的包即可

3.查看可安装的php版本

yum list php*

4.安装

这里我选择了php5.6来安装

yum -y install php56w

(实际上这里安装完php的时候，apache2.2也安装上了)

安装扩展

yum install php56w-mysql

yum install php56w-gd

yum install php56w-mbstring

重启apache

service httpd restart

============================================

安装apache2.4

执行

cd /etc/yum.repos.d

wget http://repos.fedorapeople.org/repos/jkaluza/httpd24/epel-httpd24.repo

wget http://www.hop5.in/yum/el6/hop5.repo

建议先把已安装的卸载掉(上面已有apache2.2)

查看已安装

yum list installed httpd*

卸载

yum remove httpd

查看可安装httpd

yum list httpd*

安装

yum install httpd24-httpd httpd24-httpd-devel httpd24-mod_ssl hhvm

=========================================

安装mysql5.7.15

yum方式安装(推荐)

http://dev.mysql.com/downloads/repo/yum/

以centos6.x为例

rpm -Uvh http://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm

搜索

yum list mysql*

现在可以看到mysql5.7

yum install mysql-community-server

------------------------------------------------------------分割线---------------------------

rpm方式安装

查看并卸载自带的mysql

先用rpm -qa | grep -i mysql 指令查看，然后用rpm -e  --nodeps 卸载对应的组件

官方下载

http://dev.mysql.com/downloads/mysql/

cd /

wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-common-5.7.15-1.el6.x86_64.rpm

wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-libs-5.7.15-1.el6.x86_64.rpm

wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-client-5.7.15-1.el6.x86_64.rpm

wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-server-5.7.15-1.el6.x86_64.rpm

下载以上文件到到 /目录

先安装依赖(mysql5.7需要)

yum -y install numactl

yum -y install perl

依次执行安装

rpm -ivh mysql-community-common-5.7.15-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.15-1.el6.x86_64.rpm
rpm -ivh mysql-community-client-5.7.15-1.el6.x86_64.rpm
rpm -ivh mysql-community-server-5.7.15-1.el6.x86_64.rpm

启动

service mysqld start

开机自动启动

chkconfig mysqld on

获得MySQL初始密码

grep 'temporary password' /var/log/mysqld.log

这里的 >gjpjgkb:0cX  就是root的默认密码

登录mysql

mysql -uroot -p'密码'

即  mysql -uroot -p

mysql5.7的安全机制加强，要求立即修改密码，否则无法继续操作

修改新密码

ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';

注意密码要足够复杂(8位，大写字母，小写字母，数字，特殊符号)，否则修改失败

允许远程登录

Grant all privileges on *.* to 'root'@'%' identified by 'HAOabc2016!' with grant option;

flush privileges;

----------------------------------------------------------------------------------------------------------------------- 

如何解决ERROR 1819 (HY000): Your password does not satisfy the current policy requirements呢？

必须修改两个全局参数： 
首先，修改validate_password_policy参数的值

mysql> set global validate_password_policy=0; 

再修改密码的长度

set global validate_password_length=1;

----------------------------------------------------------------------------------------------------------------------- 

MySQL的默认安装位置

/etc/my.cnf               #配置文件

/var/lib/mysql/               #数据库目录

/usr/share/mysql              #配置文件目录

/usr/bin                     #相关命令目录

/etc/init.d/mysql            #启动脚本
