安装失败：

若是导致网站不能访问，查看是否有/www/wwwroot/wordpress/.maintenance文件，若有，请删除：
1 | rm -rf /www/wwwroot/wordpress/.maintenance |
解决
步骤1：修改php配置文件php-fpm.conf
vi /www/server/php/74/etc/php-fpm.conf
修改 request_terminate_timeout = 600
upload_max_filesize = 100M
或者在宝塔面板直接修改：
步骤2：修改nginx文件nginx.conf
修改前配置
1 2 3 4 5 6 7 | fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 256k; |
调大这两个参数，修改后为：
1 2 | fastcgi_buffer_size 128k; fastcgi_buffers 8 128k; |
重启nginx
