Try this:

adb shell setprop service.adb.tcp.port 5555

adb shell stop adbd
adb shell start adbd

functions.php添加

add_action('phpmailer_init', 'mail_smtp');
function mail_smtp( $phpmailer ) {
$phpmailer->FromName = 'xxx'; // 发件人昵称
$phpmailer->Host = 'smtp.qq.com'; // 邮箱SMTP服务器
$phpmailer->Port = 465; // SMTP端口，不需要改
$phpmailer->Username = 'xxx@qq.com'; // 邮箱账户
$phpmailer->Password = 'xxx'; // 此处填写邮箱生成的授权码，不是邮箱登录密码
$phpmailer->From = 'xxx@qq.com'; // 邮箱账户同上
$phpmailer->SMTPAuth = true;
$phpmailer->SMTPSecure = 'ssl'; // 端口25时留空，465时ssl，不需要改
$phpmailer->IsSMTP();
}

UPDATE wp_posts SET post_content = REPLACE( post_content, 'oldxxx' , 'newxxx' );

UPDATE wp_options SET option_value = replace( option_value, 'oldxxx', 'newxxx' );

if ($request_uri = /xxx.htm) { return 301 https://www.xxx.com/xxx/; }

functions.php文件里添加

function disable_srcset( $sources ) {
return false;
}
add_filter( 'wp_calculate_image_srcset', 'disable_srcset' );

怎么样禁止WordPress自动剪裁上传图片？

以下三个步骤：

1. WordPress设置Settings，媒体Media，所有尺寸调为0
2. 进入wp-admin/options.php，找到medium_large_size_w设置为0
3. 可能主题中还有图片剪裁代码，搜索functions.php是否有add_image_size，thumbnails_size没有就不管了，有就注释掉

以上如果还没有效果，试试把一下代码复制到functions.php:

禁用scaled：
add_filter( 'big_image_size_threshold', '__return_false' );

禁用其他大尺寸：
function shapeSpace_disable_image_sizes($sizes) {
unset($sizes['thumbnail']);
unset($sizes['medium']);
unset($sizes['large']);
unset($sizes['medium_large']);
unset($sizes['1536x1536']);
unset($sizes['2048x2048']);
}

这个使用在reflective-vest的Vilva有效
add_action('intermediate_image_sizes_advanced', 'shapeSpace_disable_image_sizes');

function shapeSpace_disable_other_image_sizes() {
remove_image_size('post-thumbnail');
remove_image_size('another-size');
}

add_action('init', 'shapeSpace_disable_other_image_sizes');

从上到下，一个一个试吧！

文件备份

# mkdir /home/backup
# cd /home/wwwroot
# tar -zcvf XXX-2020-06-18.tar.gz XXX.com
# mv XXX-2020-06-18.tar.gz /home/backup/

# cp /home/backup/XXX.com-2020-06-18.tar.gz /home/wwwroot
# cd /home/wwwroot
# tar -zxf XXX.com-2020-06-18.tar.gz
# rm -rf XXX.com-2020-06-18.tar.gz

数据库备份

# cd /home/backup
# lnmp database list
# mysqldump -u root -p XXX > XXX-2020-06-18.sql

数据库恢复

# mysql -u root -p
# show databases;
# use XXX;
# source /home/backup/XXX.sql;

删除与新建数据库

# mysql -u root -p
# drop database XXX;
# create database XXX;

备份到其他VPS

CentOS7系统

1. 密码，BBR和冲浪

重装系统后重启下机器，不然下面的yum会报错

# passwd

保持SSH长时间在线，下面两项前#去掉并修改参数，没有就在末尾添加
# vi /etc/ssh/sshd_config
ClientAliveInterval 30
ClientAliveCountMax 5
# service sshd restart

# yum -y update

查询是KVM后安装BBR
# virt-what
可能需要# yum -y install virt-what

# wget --no-check-certificate https://github.com/teddysun/across/raw/master/bbr.sh && chmod +x bbr.sh && ./bbr.sh
可能要安装# yum -y install wget
查看BBR是否安装成功
# sysctl net.ipv4.tcp_congestion_control
是否出现
net.ipv4.tcp_available_congestion_control = bbr

2. 安装LNMP及其他

# yum -y install screen
# screen -S lnmp
# wget -c http://soft.vpser.net/lnmp/lnmp1.9-full.tar.gz && tar -zxf lnmp1.9-full.tar.gz && cd lnmp1.9-full && ./install.sh lnmp

不装InnoDB Storage Engine，安装PHP7.2，其它默认

把phpmyadmin移到其他目录
# cd /home/wwwroot/default
# mv phpmyadmin 其他目录
# rm -rf index.html

安装OPchche
# cd /root/lnmp1.9-full
# ./addons.sh install opcache

安装Memcached
# ./addons.sh install memcached

删除压缩包
# rm -rf /root/lnmp1.9-full.tar.gz

安装imageMagick
# ./addons.sh install imagemagick

3. 防火墙和修改端口

# systemctl start firewalld
# systemctl stop firewalld
# systemctl restart firewalld
# systemctl status firewalld
# systemctl enable firewalld
# systemctl disable firewalld

# firewall-cmd --permanent --zone=public --add-port=80/tcp
# firewall-cmd --permanent --zone=public --add-port=443/tcp
# firewall-cmd --permanent --zone=public --add-port=23729/tcp
# firewall-cmd --permanent --zone=public --remove-port=23729/tcp
# firewall-cmd --reload

# firewall-cmd --zone=public --list-ports
# firewall-cmd --list-ports

# vi /etc/firewalld/firewalld.conf
AllowZoneDrifting=yes 改成 no
# systemctl restart firewalld
编辑器命令模式输入 /AllowZoneDrifting进行搜索（注意有空格）

# vi /etc/ssh/sshd_config
修改SSH端口
# service sshd restart

4. 添加域名并安装WP

# lnmp vhost add
不启用PHP Pathinfo，不启用access log，其他默认
注意，添加SSL之前要提前做好域名解析

# cd /home/wwwroot/XXX.com
# wget https://wordpress.org/latest.tar.gz
# tar -zxvf latest.tar.gz
# mv wordpress/* .
# rm -rf wordpress latest.tar.gz

# chattr -i /home/wwwroot/XXX.com/.user.ini
# chattr -i /home/wwwroot/default/.user.ini && lnmp restart
# chmod -R 755 /home/wwwroot && chown -R www /home/wwwroot

或者# lnmp stop && lnmp start

https进入网址开始安装wordpress

5. WP插件

推荐插件：
WP Fastest Cache
Autoptimize
A3 Lazy Load
MemcacheD Is Your Friend
Yoast SEO
UpdraftPlus WordPress Backup Plugin
Smart Slider 3 / MetaSlider
Shortcode Table of Contents
Wordfence Security

6. 定时清理和禁用日志

定期清理VPS日志

# cd /home/wwwroot/ && wget https://www.XXX.com/shells/wwwlogs_cleaner.sh
# echo -e "10 0 */5 * * bash /home/wwwroot/wwwlogs_cleaner.sh" >> /var/spool/cron/root

清理需用到crontab
查询# crontab -l
如果没有安装，就执行# yum -y install vixie-cron crontabs

禁用MySQL日志，优化MySQL

# cp /etc/my.cnf /etc/my.cnf.old
# vi /etc/my.cnf

下面两项加#号
#log-bin=mysql-bin
#binlog_format=mixed
优化MySQL
query_cache_size = 16M
max_connections = 100
重启# /etc/init.d/mysql restart

7. SSL相关

可直接导入备份文件(对比后再导入)

# vi /usr/local/nginx/conf/vhost/XXX.com.conf
在sever{433}里面添加
add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";
禁用TLS 1.0和TLS 1.1
删除ssl_protocols项下的TLSv1.0和TLSv1.1即可

# service nginx restart
或者
# lnmp restart
或者重新加载
# nginx -s reload

hostnamectl set-hostname newname

然后修改vi /etc/hosts

重启
