不会的跟我一起操作
1.安装 libmcrypt
cd /usr/local/src/
wget http://mirrors.hust.edu.cn/epel//6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh epel-release-6-8.noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
yum install libmcrypt-devel
2.安装apache
yum install httpd
service httpd start
chkconfig --levels 235 httpd on
3.安装php7
rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
yum -y install php70w php70w-mysql php70w-mbstring php70w-mcrypt php70w-gd php70w-imap php70w-ldap php70w-odbc php70w-pear php70w-xml php70w-xmlrpc php70w-pdo
4.安装mysql，设置初始密码
yum install mysql mysql-server mysql-devel -y
service mysqld start
mysqladmin -u root password '123456'
设置对外帐号
mysql -uroot -p
123456
GRANT ALL PRIVILEGES ON *.* TO someone@"%" IDENTIFIED BY "123456" WITH GRANT OPTION;
flush privileges;
默认安装的是mysql5.1，如果要新版本5.7，这样
wget https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm
rpm -ivh mysql57-community-release-el6-9.noarch.rpm
yum install mysql-community-server
service mysqld start
mysql 5.7修改密码
1.关闭mysqld
service mysqld stop
2.关闭安全
mysqld_safe --skip-grant-tables &
3.连接
mysql -p
4.改密码
update mysql.user set authentication_string=password('123456') where user='root' and Host = 'localhost';
5.刷新
flush privileges;
quit;
如果php的pdo连接mysql5.7报错[Can't initialize character set utf8mb4]，试试下面这2句（根据自己php版本修改）
yum erase php70w-mysql
yum install php70w-mysqlnd
5.配置apache
vim /etc/httpd/conf/httpd.conf
6.配置防火墙
iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT
iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
service iptables save
cat /etc/sysconfig/iptables
修改顺序
[root@localhost ~]# cat /etc/sysconfig/iptables
# Generated by iptables-save v1.4.7 on Sun Jun 11 15:51:06 2017
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [34:5240]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
改完之后，策略并没有直接生效，需要关闭重开一下
service iptables stop
service iptables start
