Centos7.X LNMP环境部署（非源码）
1.下载新的CentOS-Base.repo#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
2.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
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
https://s1.运维网.com/images/blog/201903/27/996b676ce0e1a585e52fd755f4087ed6.png
#yum list |grep nginx
https://s1.运维网.com/images/blog/201903/27/55c8070660161b4d57c4244f737dd394.png
安装成功后，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
#nginx #启动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
https://s1.运维网.com/images/blog/201903/27/2f5ea0636b01e0fdb39938fee52a568c.png
开机启动设置
#systemctl enable nginx
#systemctl daemon-reload
3.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
查看5.7版本是否已经启用
#yum repolist all | grep mysql
https://s1.运维网.com/images/blog/201903/27/eae817f8e8f8ce6fcb5023cec9c5b89e.png
如果没有启用的话，我们可以修改源文件
#/etc/yum.repos.d/mysql-community.repo
https://s1.运维网.com/images/blog/201903/27/219158e661de17e2240a09d7a0cbbdf8.png
把enabled改为1就可以了，其他的版本改为0
修改完成之后查看可用的版本
#yum repolist enabled | grep mysql
https://s1.运维网.com/images/blog/201903/27/7a5aa0e79f1222c4c3f93711e52a3ba5.png
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
https://s1.运维网.com/images/blog/201903/27/809366b148fe50be0bd6e71f7738398d.png
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
https://s1.运维网.com/images/blog/201903/27/404d97231337ac98633d4a2ab4ff5e95.png
登录MySql并修改root密码
#mysql -uroot -p
mysql>ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
扩展阅读：mysql的密码策略
mysql>show variables like '%password%';
https://s1.运维网.com/images/blog/201903/27/fff89a8d49b331b2f83fc8338addb752.png
默认的密码策略
https://s1.运维网.com/images/blog/201903/27/9cc911530683856945c65fc13a2b617d.png
修改密码策略
在/etc/my.cnf文件添加validate_password_policy配置：
https://s1.运维网.com/images/blog/201903/27/138cd9736cedd40ebf4cb6f2777ffbdf.png
修改默认编码
在/etc/my.cnf配置文件的下添加编码配置：
https://s1.运维网.com/images/blog/201903/27/f24c477a2234c23c9a9b2fc3ecd530d4.png
重启mysql，是修改生效
#systemctl restart mysqld
远程登录用户添加
mysql>grant all privileges on . to 用户名@'%' identified by '密码' with grant option;
mysql> FLUSH PRIVILEGES;
查看用户
mysql> select host,user from mysql.user;
https://s1.运维网.com/images/blog/201903/27/dcbd265afed9903c799a663d553ba3e3.png
记得关SELinux
4.安装PHP7
5.#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
https://s1.运维网.com/images/blog/201903/27/b0e6735e14e55a647ce7a5e09f8d2d6b.png
重启Nginx使修改生效
