三、设置域名解释
域名解释生效方可继续一下步，否则Let’s Encrypt证书生成会失败。浏览器输入主机IP地址，如果能显示“恭喜您，LNMP一键安装包安装成功！……”的页面，即代表域名解释生效并且lnmp安装成功
四、添加虚拟主机，运行：lnmp vhost add，根据提示：
1.添加网站域名，例如knowwei.xxx
2.如果有，继续添加网站域名，例如www.knowwei.xxx，无即直接回车
2.设置网站的目录，如果需要自定义目录，必须输入完整路径，例如/home/wwwroot/www.knowwei，否则网站目录将设置在/root/下
3.启用rewrite伪静态，输入y。如果不启用（输入n），wordpress的固定链接设置将不可用
4.rewrite规则为：wordpress
5.启用日志输入y ，不启用输入n
6.输入日志文件名
7.数据库名称和数据库用户名设置是否相同，输入y
8.验证MySQL root password，输入时不会显示字符

五、安装Wordpress
到https://cn.wordpress.org/txt-download/查看最新版本的Wordpress tar.gz文件路径，逐条执行下面命令：
1.切换到网站目录
2.下载最新版本Wordpress压缩包
3.解压文件
4.将解压后文件移至网站目录
5.删除压缩包和解压后留下的目录
6.修改目录的拥有者和组为www
cd /home/wwwroot/www.knowwei
wget https://cn.wordpress.org/latest-zh_CN.zip
unzip latest-zh_CN.zip
mv wordpress/* .
rm -rf wordpress latest-zh_CN.zip
chattr -i /home/wwwroot/www.knowwei/.user.ini
chown -R www:www /home/wwwroot/www.knowwei
浏览器输入网址http://knowwei.xxx，根据提示填入相对应的信息，Wordpress安装完毕。
六、注意的问题
1.强制http 301跳转到https，修改ngnix配置文件“/usr/local/nginx/conf/vhost/www.knowwei.conf”即可实现，将监听80端口部分修改为
server
{
listen 80;
server_name knowwei.xxx www.knowwei.xxx;
return 301 https://www.knowwei.xxx$request_uri;
}
以下此部分不变
server
{
listen 443 ssl http2;
……
}
2.Wordpress只能显示默认的安装主题，原因为PHP禁用了“scandir”函数，打开“/usr/local/php/etc/php.ini”文件，搜索“scandir,”，删除后保存即可。
……
; This directive allows you to disable certain functions for security reasons.
; It receives a comma-delimited list of function names.
; http://php.net/disable-functions
disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server
……
3.基于安全考虑，建议修改phpmyadmin目录名，位置“/home/wwwroot/default/”。例如将目录名称修改为“php-admin-comeonbaby666”，修改完毕后phpmyadmin的网址相应变更为：http://ip/php-admin-comeonbaby666
