名词解释：
LNMP：Linux+Nginx+MySql+PHP
LAMP：LInux+Apache+MySql+PHP
Nginx的正确读法应该是Engine X
我们使用CentOS自带的YUM来安装
镜像源切换
先把YUM源切换成国内的镜像源
先备份一下原来的源镜像文件
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
下载新的CentOS-Base.repo
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
如果没有安装wget的话可以使用#yum install wget安装完成之后，在执行CentOS-Base.repo的安装
对/etc/yum.repos.d/CentOS-Media.repo源文件配置文件，改为不生效
enable=0
YUM缓存生成
yum clean all
yum makecache
yum update
安装Nginx
YUM源中没有Nginx，我们需要增加一个nginx的源nginx.repo
vi /etc/yum.repos.d/nginx.repo
源文件的内容
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
查看Nginx是否配置成功
yum list nginx

提示成功后，就可以直接安装nginx了
yum -y install nginx
安装的就是Nginx官网的最新版本，启动Nginx
nginx
可以使用curl命令查看是否安装成功
curl 127.0.0.1
如果安装成功的话，就会看到输出一个HTML的一个反馈

安装MySql（5.7）
官网：http://dev.mysql.com/downloads/repo/yum/
rpm -Uvh http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm

修改完成之后查看可用的版本
yum repolist enabled | grep mysql

mysql-tools-community/x86_64 MySQL Tools Community 38
mysql57-community/x86_64 MySQL 5.7 Community Server 146
如果看到5.7版本启用了之后就可以安装MySql了
yum -y install mysql-community-server
安装完成之后，就可以启动mysql了
service mysqld start
查看MySql的启动状态
service mysqld status
Redirecting to /bin/systemctl status mysqld.service

开机启动设置
systemctl enable mysqld
systemctl daemon-reload
MySql安装完成之后会在LOG文件(/var/log/mysqld.log)中生成一个root的默认密码
grep 'temporary password' /var/log/mysqld.log
2017-05-23T14:51:45.705458Z 1 [Note] A temporary password is generated for root@localhost: dersqr7dcfer
登录MySql并修改root密码
#mysql -uroot -p
mysql>ALTER USER 'root'@'localhost' IDENTIFIED BY 'new psd';
扩展阅读：mysql的密码策略
show variables like '%password%';
+---------------------------------------+--------+
| Variable_name | Value |
+---------------------------------------+--------+
| default_password_lifetime | 0 |
| disconnect_on_expired_password | ON |
| log_builtin_as_identified_by_password | OFF |
| mysql_native_password_proxy_users | OFF |
| old_passwords | 0 |
| report_password | |
| sha256_password_proxy_users | OFF |
| validate_password_check_user_name | OFF |
| validate_password_dictionary_file | |
| validate_password_length | 8 |
| validate_password_mixed_case_count | 1 |
| validate_password_number_count | 1 |
| validate_password_policy | MEDIUM |
| validate_password_special_char_count | 1 |
+---------------------------------------+--------+
14 rows in set (0.01 sec)
默认的密码策略
validate_password_policy：密码策略，默认为MEDIUM策略
validate_password_dictionary_file：密码策略文件，策略为STRONG才需要
validate_password_length：密码最少长度
validate_password_mixed_case_count：大小写字符长度，至少1个
validate_password_number_count ：数字至少1个
validate_password_special_char_count：特殊字符至少1个
修改密码策略
在/etc/my.cnf文件添加validate_password_policy配置：
选择0（LOW），1（MEDIUM），2（STRONG）其中一种，选择2需要提供密码字典文件
validate_password_policy=0
修改默认编码
在/etc/my.cnf配置文件的[mysqld]下添加编码配置：
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'
重启mysql，是修改生效
systemctl restart mysqld
远程登录用户添加
GRANT ALL PRIVILEGES ON *.* TO 'test'@'%' IDENTIFIED BY '1qazTTEw@.' WITH GRANT OPTION;
FLUSH PRIVILEGES;
查看用户
select host,user from mysql.user;
由于开始没有关闭SELinux，引起mysql连接失败的解决：

安装PHP7
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
安装PHP7
yum install php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64 php70w-mysql.x86_64 php70w-pdo.x86_64
安装php-fpm
yum install php70w-fpm php70w-opcache
启动php-fpm
systemctl start php-fpm
开机启动设置
systemctl enable php-fpm
systemctl daemon-reload
修改根目录
修改 /etc/nginx/conf.d/default.conf
location ~ \.php$ {
root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
重启Nginx使修改生效
