一、路徑添加到環境變量php
$vi /etc/profile #執行生效 $source /etc/profile
二、添加新用戶node
#添加www用戶並設置組 $useradd www $chown -R www:www /home/www/src/testweb/
三、查看文件夾下各個文件的大小linux
$du -h *
四、查看硬盤及分區nginx
$lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vda 253:0 0 50G 0 disk └─vda1 253:1 0 50G 0 part / $fdisk -l Disk /dev/vda: 53.7 GB, 53687091200 bytes, 104857600 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x0005fc9a Device Boot Start End Blocks Id System /dev/vda1 * 2048 104857599 52427776 83 Linux
五、cache緩存清除web
對於小內存系統,常常發現cache被佔滿,致使系統很卡,可手動進行清理redis
#查看默認值 0 $cat /proc/sys/vm/drop_caches #清除前將緩存內容寫入到磁盤 $sync #寫入參數值 $echo 3 > /proc/sys/vm/drop_caches
參數官方文檔解釋緩存
Writing to this will cause the kernel to drop clean caches, dentries and inodes from memory, causing that memory to become free.
To free pagecache:
* echo 1 > /proc/sys/vm/drop_caches
To free dentries and inodes:
* echo 2 > /proc/sys/vm/drop_caches
To free pagecache, dentries and inodes:
* echo 3 > /proc/sys/vm/drop_caches
As this is a non-destructive operation, and dirty objects are notfreeable, the user should run "sync" first in order to make sure allcached objects are freed.
This tunable was added in 2.6.16.swoole
一、查看php已有的擴展模塊ide
$php -m #或/usr/local/php/bin/php -m
二、啓動php-fpmphp-fpm
$service php-fpm start #或/usr/local/php/sbin/php-fpm $service php-fpm restart #重啓 $service php-fpm stop #中止 $killall php-fpm #中止 $ps aux |grep php-fpm #查看php-fpm進程啓動是否ok
三、查看php信息
#查看ini配置 $php --ini #查看php信息 $php -i #可根據須要grep 或 php --info|grep swoole
四、查看php版本
$php -v #或/usr/local/php/bin/php -v
五、phpize
phpize是用來擴展php擴展模塊的,經過phpize能夠創建php的外掛模塊
$phpize #編譯 $./configure #安裝 $make && make install
一、查看nginx版本
$nginx -v #查看完成的nginx配置信息 $nginx -V nginx version: nginx/1.12.2 built by gcc 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC) built with OpenSSL 1.0.1e-fips 11 Feb 2013 TLS SNI support enabled configure arguments: --prefix=/usr/local/nginx --with-http_stub_status_module --with-pcre --with-http_ssl_module --with-http_gzip_static_module --with-http_gunzip_module --with-stream
二、檢查ngix.conf配置文件
$nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successfu
三、啓動nginx
$service nginx start #nginx -s reload 或/usr/local/nginx/sbin/nginx 或nginx $service nginx restart #重啓 $nginx -s stop #中止
一、統計某個key值數量
redis-cli -p 6379 -h 192.168.10.234 -n 2 keys "kmads:km_wechat_subscribe:custom:*"|wc -l
