今天完成的任务：
1.nginx延时统计
首先在/var/log/nginx 下vi新文件statistics.txt,作为shell脚本，内容入下：
cat access.log |sed -rn '/21\/Apr\/2017/p' > statistics.txt
#统计statistics.txt里面有多少个ip访问
cat statistics.txt |awk '{print $1}'|sort |uniq > ipnum.txt
#通过shell统计每个ip访问次数
for i in `cat ipnum.txt`
do
iptj=`cat access.log |grep $i | grep -v 400 |wc -l`
echo "ip地址"$i"在2017-4-21日全天(24小时)累计成功请求"$iptj"次，平均每分钟请求次数为："$(($iptj/1440)) >> result.txt
done
#统计响应时间小于600ms的访问数量
echo "小于600ms响应时间访问数量："$a >> result.txt
echo "小于600ms响应时间访问数量："cat ${access} | awk ' {if(s10<600) a=a+1} END{print a;}'
#统计响应时间大于800ms的访问数量
echo "大于800ms响应时间访问数量："$b >> result.txt
echo "大于800ms响应时间访问数量："cat ${access} | awk ' {if(s10>800) b=b+1} END{print b;}'
AWK，一种文本处理工具，和grep,sed类似，利用一些特定语法格式的命令来完成对文件的操作。
打印出的日志如下：
2.Apache,Nginx,Tomcat,Jetyy,Resin的区别，及其它收费http服务器，和浏览器之间的关系。
Apache Http Server是老牌的服务器，在市场的占有率一直很高，最高达到70%，最近数据仍然有21.79%而且是开源免费。 Apache Software Foundation就是在维护Apache Http Server的过程中衍生出来的组织，它的诞生早与现在的绝大多数Apache Project,而且仍在维护，它和Nginx一样是免费服务器中面向HTTP的，关注的问题是反向代理了，负载均衡，域名协作，http解析这些比较宏观的对象，Nginx对于高并发有特别的优势，并且本身部署方便。Tomcat和Jetty在解析jsp页面，运行Java类程序有独特优势，所以一般部署在具体的项目运行层面，比较关注项目里具体的业务实现，Resin和Tomcat差不多，在监控功能方便稍微比Tomcat强一些，但Tomcat是Apache旗下，相关的资料多，方便参考。另外收费的web server还有微软的IIS，谷歌的GWS,等等，也可以实现相关的功能。下面是一张最近份额统计图：
3.Resin安装,查看日志。
一开始下载的是resin3,和resin4有很大不同，安装后无法启动，过程如下

ubuntu@VM-133-216-ubuntu:/usr/local$
从新下载安装包resin-4.0.36进行安装
必须先进到resin-4.0.36目录下才可以使用下面的 ./configure 命令，我开始的时候在/usr/local下折腾了好一会
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36# ./configure --prefix=/usr/local/resin-4.0.36 --with-java-home=/usr/jvm/jdk1.8.0_121 --enable-64bit

文件配置完毕，现在开始启动resin，过程中对Linux的目录了解不深，遇到一些低级错误，最后启动成功。
使用service命令没有启动成功，第一次命令输错，软件名写错
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36# servic resin start
No command 'servic' found, did you mean:
Command 'service' from package 'init-system-helpers' (main)
servic: command not found
第二次软件名写错
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36# service resin start
Failed to start resin.service: Unit resin.service not found.
第三次命令输对了，但还是启动不了
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36# service resin-4.0.36 start
Failed to start resin-4.0.36.service: Unit resin-4.0.36.service not found.
换一种方式启动，目录名应该是resin-4.0.36
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36# /usr/local/resion/bin/resin.sh start
-su: /usr/local/resion/bin/resin.sh: No such file or directory
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36# /usr/local/resion-4.0.36/bin/resin.sh start
-su: /usr/local/resion-4.0.36/bin/resin.sh: No such file or directory
进入到bin中查看
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36# cd bin
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36/bin# ls
resinctl resinctl.in resin.sh start.bat stop.bat
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36/bin# cd resin.sh
-su: cd: resin.sh: Not a directory
搜索网络资料，用另外一种方式启动，启动成功
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36/bin# sh resin.sh start
Resin/4.0.36 launching watchdog at 127.0.0.1:6600
Resin/4.0.36 started -server 'app-0' with watchdog at 127.0.0.1:6600
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36/bin# sh resin.sh stop
Resin/4.0.36 stopped for watchdog at 127.0.0.1:6600
为了找到前一种方法启动失败的原因，做实验进行分析，退出resin相关的目录，到根目录下
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36/bin# cd ..
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36# cd ..
root@VM-133-216-ubuntu:/usr/local# cd ..
root@VM-133-216-ubuntu:/usr# cd ..
再次使用前面的方法启动，启动成功
root@VM-133-216-ubuntu:/# /usr/local/resin-4.0.36/bin/resin.sh start
Resin/4.0.36 launching watchdog at 127.0.0.1:6600
Resin/4.0.36 started -server 'app-0' with watchdog at 127.0.0.1:6600
继续分析，这种启动方式是不是和当前所在的目录有关，如果当前所在目录不同，启动命令也要做修改，做实验以验证
root@VM-133-216-ubuntu:/# cd /usr
root@VM-133-216-ubuntu:/usr# /local/resin-4.0.36/bin/resin.sh stop
-su: /local/resin-4.0.36/bin/resin.sh: No such file or directory
root@VM-133-216-ubuntu:/usr# sh resin.sh stop
sh: 0: Can't open resin.sh

root@VM-133-216-ubuntu:/usr/local/resin-4.0.36/bin# sh resin.sh stop
Resin/4.0.36 stopped for watchdog at 127.0.0.1:6600
root@VM-133-216-ubuntu:/usr/local/resin-4.0.36/bin# cd ..

No command 'usr' found, did you mean:
Command 'ssr' from package 'soundscaperenderer-common' (universe)
Command 'ur' from package 'libur-perl' (universe)
Command 'csr' from package 'rheolef' (universe)
Command 'sr' from package 'surfraw' (universe)
Command 'sur' from package 'subtle' (universe)
usr: command not found
最后得出结论，这种启动方式，实际上是在当前目录给计算机一个路径，而这个路劲是以当前目录为起点，计算机才知道怎么做，最后实验从当前目录指定到相关启动目录，resin启动成功，对Linux操作系统又有了新的认识
root@VM-133-216-ubuntu:/# cd usr
root@VM-133-216-ubuntu:/usr# local/resin-4.0.36/bin/resin.sh start
Resin/4.0.36 launching watchdog at 127.0.0.1:6600
Resin/4.0.36 started -server 'app-0' with watchdog at 127.0.0.1:6600
root@VM-133-216-ubuntu:/usr#
启动成功，查看日志
root@VM-133-216-ubuntu:/usr# netstat -nltp

明天的计划：
明天开始任务四，了解动态页面，静态页面，设计DB数据库。
遇到的问题：
往往碰到的问题，都是细节的操作造成的，需要边学习边总结。可能这些操作问题，如果不记录下来，过了自己都忘了，起不到改正进步的效果。只理解是不对的，操作的习惯也很重要。
收获：
今天用了全新的写日志方法，将自己学习的过程进行了记录。对于细节碰到的问题有了新发现，以后可以试用一段时间这种方式。比较总结型的和记录型的日志方式的区别。加油！
