1.檢查當前安裝的PHP包

yum list installed | grep php

如果要刪除，可執行

yum remove php.x86_64 php-cli.x86_64 php-common.x86_64 php-gd.x86_64 php-ldap.x86_64 php-mbstring.x86_64 php-mcrypt.x86_64 php-mysql.x86_64 php-pdo.x86_64

2.rpm包

CentOs 5.x

rpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm

CentOs 6.x
rpm -Uvh http://

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

如果想刪除上面安裝的包，重新安裝
rpm -qa | grep webtatic
rpm -e  上面搜尋到的包即可

3.檢視可安裝的php版本

yum list php*

4.安裝

這裡我選擇了php5.6來安裝

yum -y install php56w.x86_64

(實際上這裡安裝完php的時候，apache2.2也安裝上了)

安裝php-mysql擴充套件

yum install php56w-mysql

安裝mbstring擴充套件

yum install php56w-mbstring

編輯php.ini檔案

vi /etc/php.ini

加入一行

extension=mbstring.so  //經測試，可以不加這行

重啟apache

service httpd restart

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

安裝apache2.4

執行

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

建議先把已安裝的解除安裝掉(上面已有apache2.2)

檢視已安裝

yum list installed httpd*

解除安裝

yum remove httpd

檢視可安裝httpd

yum list httpd*

安裝

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

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

安裝mysql5.7.15

yum方式安裝(推薦)

以centos6.x為例

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

搜尋

yum list mysql*

yum install mysql-community-server

------------------------------------------------------------分割線---------------------------

rpm方式安裝

檢視並解除安裝自帶的mysql

先用rpm -qa | grep -i mysql 指令檢視，然後用rpm -e  --nodeps 解除安裝對應的元件

官方下載

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

下載以上檔案到到 /目錄

先安裝依賴(mysql5.7需要)

yum -y install numactl

yum -y install perl

依次執行安裝

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

啟動

service mysqld start

開機自動啟動

chkconfig mysqld on

獲得MySQL初始密碼

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

這裡的 >gjpjgkb:0cX  就是root的預設密碼

登入mysql

mysql -uroot -p'密碼'

即  mysql -uroot -p'>gjpjgkb:0cX'

mysql5.7的安全機制加強，要求立即修改密碼，否則無法繼續操作

修改新密碼

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

注意密碼要足夠複雜(8位，大寫字母，小寫字母，數字，特殊符號)，否則修改失敗

允許遠端登入

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

flush privileges;
