nginx日志切割方法

2018/12/26 | Nginx | chenjie | 暂无评论 | 527 views

使用脚本

#!/bin/bash
#日志目录
log_files_path="/data/wwwlogs/"
#待迁入日志目录
log_files_dir=${log_files_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")
#需要切割的日志www.chenjie.info_nginx.log则写入www.chenjie.info_nginx，多个日志用空格分隔
log_files_name=(www.chenjie.info_nginx www.teamfat.cn_nginx)
#日志保存天数
save_days=7

mkdir -p $log_files_dir

log_files_num=${#log_files_name[@]}

for((i=0;i<$log_files_num;i++));do
mv ${log_files_path}${log_files_name[i]}.log ${log_files_dir}/${log_files_name[i]}_$(date -d "yesterday" +"%Y%m%d").log
done
#删除过期日志
find $log_files_path -mtime +$save_days -exec rm -rf {} \; 
#重新打开日志
kill -USR1 `ps axu | grep "nginx: master process" | grep -v grep | awk '{print $2}'`

#待迁入日志目录

log_files_dir=${log_files_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")

#需要切割的日志www.chenjie.info_nginx.log则写入www.chenjie.info_nginx，多个日志用空格分隔

log_files_name=(www.chenjie.info_nginx www.teamfat.cn_nginx)

#日志保存天数

save_days=7

mkdir -p $log_files_dir

log_files_num=${#log_files_name[@]}

for((i=0;i<$log_files_num;i++));do

mv ${log_files_path}${log_files_name[i]}.log ${log_files_dir}/${log_files_name[i]}_$(date -d "yesterday" +"%Y%m%d").log

done

#删除过期日志

find $log_files_path -mtime +$save_days -exec rm -rf {} \;

#重新打开日志

kill -USR1 `ps axu | grep "nginx: master process" | grep -v grep | awk '{print $2}'`

然后加入crontab

0 0 * * * /root/cut_nginx_log.sh

1	0 0 * * * /root/cut_nginx_log.sh

提醒：因为nginx日志写入是基于文件描述符，所以在kill -USR1之前的日志仍会向已经移动的原日志中追加写入。使用配置在server块中增加 [crayon-5d0……

博客搬家流水账

2018/12/23 | MyRecord | chenjie | 暂无评论 | 524 views

前因从2011年开始写博客到现在也不知道搬过多少次，有因为性价比搬迁到海外的，有因为速度搬迁到香港，有因为想使用一些cdn资源需要备案搬迁到国内的，这次搬迁从阿里云虚拟主机搬迁到腾讯云主要还是因为虚拟主机受限较多，不支持自动备份，https等。迁备案现在各家idc接入基本都需要接入备案，因为我之前换过身份证，主体信息需要变更，也就是……

php+zookeeper 集群管理

上一篇提到了php操作zookeeper的一些常用curd操作和需要注意的问题本篇主要说下具体zookeeper的一种应用场景：集群管理（图片来自网络）在此我们主要关注两点监听机器的退出加入上图中所有机器约定在父节点GroupMembers下创建临时节点，然后监听父节点的子节点。一旦有机器挂掉，该机器与zookeeper的连接断开……

php+zookeeper的curd操作

2018/03/22 | PHP,开源社区 | chenjie | 2 条评论 | 3915 views

上一篇讲了一些安装流程，这篇来看下常用函数 http://php.net/manual/zh/book.zookeeper.php 我们用的比较多的应该是

public function connect( $host, $watcher_cb = null, $recv_timeout = 10000) {}

public function create( $path, $value, $acl, $flags = null ) {}
<?php
$zookeeper = new Zookeeper('locahost:2181');
$aclArray = array(
  array(
    'perms'  => Zookeeper::PERM_ALL,
    'scheme' => 'world',
    'id'     => 'anyone',
  )
);
$path = '/path/to/newnode';
$realPath = $zookeeper->create($path, null, $aclArray);
if ($realPath)
  echo $realPath;
else
  echo 'ERR';
?>

public function delete( $path, $version = -1 ) {}
<?php
$zookeeper = new Zookeeper('locahost:2181');
$path = '/path/to/node';
$r = $zookeeper->delete($path);
if ($r)
  echo 'SUCCESS';
else
  echo 'ERR';
?>

public function set( $path, $data, $version = -1, &$stat = null ) {}
<?php
$zookeeper = new Zookeeper('locahost:2181');
$path = '/path/to/node';
$value = 'nodevalue';
$r = $zookeeper->set($path, $value);
if ($r)
  echo 'SUCCESS';
else
  echo 'ERR';
?>

public function get( $path, $watcher_cb = null, &$stat = null, $max_size = 0) {}
<?php
$zookeeper = new Zookeeper('locahost:2181');
$path = '/path/to/node';
$value = 'nodevalue';
$zookeeper->set($path, $value);

$r = $zookeeper->get($path);
if ($r)
  echo $r;
else
  echo 'ERR';
?>

public function getChildren( $path, $watcher_cb = null ) {}
<?php
$zookeeper = new Zookeeper('locahost:2181');
$path = '/zookeeper';
$r = $zookeeper->getchildren($path);
if ($r)
  var_dump($r);
else
  echo 'ERR';
?>

public function exists( $path, $watcher_cb = null ) {}
<?php
$zookeeper = new Zookeeper('locahost:2181');
$path = '/path/to/node';
$r = $zookeeper->exists($path);
if ($r)
  echo 'EXISTS';
else
  echo 'N/A or ERR';
?>
