CentOS 7 安装 lnmp

• 本地远程连接服务器

1. 安装 ssh 服务

yum install ssh

2. 启动 ssh

service sshd start  
chkconfig sshd on

1. yum 换源

yum update

2. 安装nginx

yum localinstall http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

yum repolist enabled | grep "nginx*" 

yum -y install nginx

• 启动 nginx

service nginx start

• 设置 nginx 开机自启动

systemctl enable nginx.service

• 检查 nginx 自启动设置是否成功

systemctl list-dependencies | grep nginx

• 浏览器输入你的 ip 检测是否安装成功，如出现欢迎页面，则 nginx 安装成功

• nginx 配置如下

  server{
  listen  80;
  server_name youserver;
  index index.html index.php;
  root /home/public;  //你的项目路径
  #charset koi8-r;
  #access_log logs/host.access.log main;
  location / {
  index index.html index.htm index.php;
  try_files $uri $uri/ /index.php?$query_string;
  }
  error_page 404    /404.html;
  # redirect server error pages to the static page /50x.html
  #
  error_page 500 502 503 504 /50x.html;
  location = /50x.html {
  root html;
  }
  # proxy the PHP scripts to Apache listening on 127.0.0.1:80
  #
  #location ~ .php$ {
  # proxy_pass http://127.0.0.1;
  #}
  # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
  #
  location ~ .php$ {
  root   /home/public;
  fastcgi_pass 127.0.0.1:9000;
  fastcgi_index index.php;
  fastcgi_param SCRIPT_FILENAME /home/public$fastcgi_script_name;
  include  fastcgi_params;
  }
  # deny access to .htaccess files, if Apache's document root
  # concurs with nginx's one
  #
  location ~ /.ht {
  deny all;
  }
  }
  

3. 安装 mysql

   yum -y localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
   
   yum repolist enabled | grep "mysql.*-community.*"
   
   yum -y install mysql-community-server install mysql-community-devel

   • 启动 mysql

   service mysqld start

   • 检查 mysql 是否启动成功

   service mysqld status 或者 ps -ef | grep mysql

   • 设置 mysql 开机自启动

   systemctl enable mysqld.service

   • 检查 mysql 开机自启动是否设置成功

   systemctl list-dependencies | grep mysqld

   • 更换 mysql root 用户密码

   mysql5.7 以后的争强了安全机制,所以使用yum安装,系统会自动生成一个随机的密码，并且不能设置简单密码。所以需要修改 mysql 全局参数
   
   先用日志密码登录 mysql 
   
   grep 'temporary password' /var/log/mysqld.log
   
   会输出结果: A temporary password is generated for root@localhost: ******
   
   使用此密码登录后 执行 SHOW VARIABLES LIKE 'validate_password%‘;  查看 mysql 密码策略
   
   +--------------------------------------+--------+
   | Variable_name                        | Value  |
   +--------------------------------------+--------+
   | 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      |
   +--------------------------------------+--------+
   
   执行 set global validate_password_policy=LOW;  修改密码策略
   
   执行 set global validate_password_length=6; 修改验证密码长度
   
   切换 user 库
   
   update user set authentication_string = password('root'), password_expired = 'N', password_last_changed = now() where user = 'root';
   
   重启 mysqld 服务，再用新密码登录即可
   
   如果无法登录,提示Access denied for user 'root'@'localhost'
   
   重新更新 root 用户的 plugin 字段
   
   update user set plugin='mysql_native_password' where user = 'root';
   
   更新成功后.重新执行更新密码操作
   
   刷新权限  flush privileges;
