Web.config?配置

Ubuntu?服務(wù)器配置

1. 停用Ubuntu默認(rèn)的防火墻服務(wù) ( Ubuntu防火墻服務(wù)名稱為: ufw.service 或者?apparmor.service )

myuser@ubsrv:~/ans$ sudo systemctl status apparmor.service myuser@ubsrv:~/ans$ sudo systemctl stop apparmor.service myuser@ubsrv:~/ans$ sudo systemctl disable apparmor.service myuser@ubsrv:~/ans$

2. 上傳部署文件

myuser@ubsrv:~/ans$ ls ans_rproxy app.json libev.so.4 myuser@ubsrv:~/ans$ file ans_rproxy ans_rproxy3: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.24, BuildID[sha1]=bd061a62e823bd0f734b20e4c4ffb03cf58b13f7, not stripped myuser@ubsrv:~/ans$

3. 設(shè)置ans_rproxy程序的動(dòng)態(tài)鏈接庫(kù)路徑

myuser@ubsrv:~/ans$ chmod +x ./patchelf myuser@ubsrv:~/ans$ ./patchelf --set-rpath ".:./lib:/usr/local/ans/ans_rproxy/lib:/opt/ans/ans_rproxy/lib" ./ans_rproxy myuser@ubsrv:~/ans$ myuser@ubsrv:~/ans$ ./patchelf --print-rpath ./ans_rproxy .:./lib:/usr/local/ans/ans_rproxy/lib:/opt/ans/ans_rproxy/lib myuser@ubsrv:~/ans$

4. 查看ans_rproxy程序所需的動(dòng)態(tài)鏈接庫(kù)是否存在

若使用系統(tǒng)提供的庫(kù) libev.so.4 ,?可以安裝執(zhí)行命令安裝對(duì)應(yīng)的庫(kù)文件 sudo aptitude install libev4

myuser@ubsrv:~/ans$ chmod +x ./ans_rproxy myuser@ubsrv:~/ans$ ldd ./ans_rproxy linux-vdso.so.1 => (0x00007ffd9b591000)libev.so.4 => ./libev.so.4 (0x00007f19aa342000)libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f19a9f78000)libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f19a9c6f000)/lib64/ld-linux-x86-64.so.2 (0x00007f19aa550000) myuser@ubsrv:~/ans$

5. 添加rd_public用戶

備注: Centos?的刪除用戶命令(?userdel -fr rd_public )和添加用戶命令(?useradd -U rd_public )

myuser@ubsrv:~/ans$ sudo deluser -fr rd_public Removing user `rd_public' ... Warning: group `rd_public' has no more members. Done. myuser@ubsrv:~/ans$ myuser@ubsrv:~/ans$ sudo adduser --disabled-login --gecos 'rd_public' rd_public Adding user `rd_public' ... Adding new group `rd_public' (1001) ... Adding new user `rd_public' (1001) with group `rd_public' ... Creating home directory `/home/rd_public' ... Copying files from `/etc/skel' ... myuser@ubsrv:~/ans$ myuser@ubsrv:~/ans$ sudo -u rd_public -H id uid=1001(rd_public) gid=1001(rd_public) groups=1001(rd_public) myuser@ubsrv:~/ans$

6. 創(chuàng)建工作目錄/opt/ans/ans_rproxy

myuser@ubsrv:~/ans$ sudo mkdir -p /opt/ans/ans_rproxy myuser@ubsrv:~/ans$ sudo chown -R rd_public:rd_public /opt/ans/ans_rproxy myuser@ubsrv:~/ans$ sudo -u rd_public -H cp -Rf ./* /opt/ans/ans_rproxy myuser@ubsrv:~/ans$ cd /opt/ans/ans_rproxy myuser@ubsrv:/opt/ans/ans_rproxy$ ls -alh . drwxr-xr-x 2 rd_public rd_public 4.0K Sep 14 13:50 . drwxr-xr-x 3 root root 4.0K Sep 14 13:20 .. -rwxr-xr-x 1 rd_public rd_public 359K Sep 14 13:50 ans_rproxy -rw-r--r-- 1 rd_public rd_public 324 Sep 14 13:50 app.json -rw-r--r-- 1 rd_public rd_public 55K Sep 14 13:50 libev.so.4 myuser@ubsrv:/opt/ans/ans_rproxy$

7. 修改配置文件app.json
注意: 默認(rèn)日志文件?在 Ubuntu?上為 /var/log/syslog? 在 CentOS 上為 /var/log/messages
添加的虛擬服務(wù)器列表的權(quán)重值相加的和一定要為100

myuser@ubsrv:/opt/ans/ans_rproxy$ sudo ./ans_rproxy -m
machine code: [XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]
Please send the above machine code to High-Galaxy Corp.
myuser@ubsrv:/opt/ans/ans_rproxy$?
myuser@ubsrv:/opt/ans/ans_rproxy$ sudo -u rd_public -H vim ./app.json {
"license": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX","quiet" : 0,"syslog": 0,"user": "rd_public","group": "rd_public","working_dir": "/opt/ans/ans_rproxy","vservers": [{"host" : "172.16.204.50","port" : "8081","weight" : 60},{"host" : "172.16.204.53","port" : "8081","weight" : 40}] } myuser@ubsrv:/opt/ans/ans_rproxy$

8. 測(cè)試服務(wù)器是否可以正常訪問(wèn)

myuser@ubsrv:/opt/ans/ans_rproxy$ curl -I http://172.16.204.50:8081/LoginFuZai.aspx HTTP/1.1 200 OK Cache-Control: private Content-Length: 1624 Content-Type: text/html; charset=utf-8 Server: Microsoft-IIS/7.5 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Mon, 17 Sep 2018 08:29:26 GMTmyuser@ubsrv:/opt/ans/ans_rproxy$ myuser@ubsrv:/opt/ans/ans_rproxy$ curl -I http://172.16.204.53:8081/LoginFuZai.aspx HTTP/1.1 200 OK Cache-Control: private Content-Length: 1624 Content-Type: text/html; charset=utf-8 Server: Microsoft-IIS/7.5 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Mon, 17 Sep 2018 08:29:34 GMTmyuser@ubsrv:/opt/ans/ans_rproxy$

9. 使用rd_public用戶啟動(dòng)ans_rproxy程序
注意：這里啟動(dòng)會(huì)報(bào)錯(cuò)，提示【create_listen: Permission denied】

myuser@ubsrv:/opt/ans/ans_rproxy$ sudo -u rd_public -H ./ans_rproxy -f ./app.json user [rd_public] group [rd_public] working dir [/opt/ans/ans_rproxy] Added 2 virtual servers. 20180914T153123.728231 [ 3967] create_listen: Permission denied 20180914T153123.728341 [ 3967] run_proxy: Failed to create listens. myuser@ubsrv:/opt/ans/ans_rproxy$

10. 使用sudo調(diào)用root用戶權(quán)限，啟動(dòng)ans_rproxy程序

myuser@ubsrv:/opt/ans/ans_rproxy$ sudo ./ans_rproxy -f ./app.json user [rd_public] group [rd_public] working dir [/opt/ans/ans_rproxy] Added 2 virtual servers. Created listen socket [6]. Created listen socket [7]. start_workers: start(0), count(1) ansrpxy: initialization complete rd_public: uid(1001), gid(1001) In child process with uid (1001) 20180914T154306.928568 [ 3974] {core} Process 0 online 20180914T154306.928816 [ 3974] Worker 0: listen on 6 20180914T154306.928846 [ 3974] Worker 0: listen on 7 20180914T154306.928907 [ 3974] Worker 0 : in event loop. ...... myuser@ubsrv:/opt/ans/ans_rproxy$ myuser@ubsrv:/opt/ans/ans_rproxy$ sudo ps -waux | grep ans_rproxy | grep -v grep root 4114 0.0 0.1 52700 3928 pts/0 S+ 15:51 0:00 sudo ./ans_rproxy -f ./app.json root 4115 0.0 0.0 9648 968 pts/0 S+ 15:51 0:00 ./ans_rproxy -f ./app.json rd_publ+ 4116 0.0 0.0 18096 1816 pts/0 S+ 15:51 0:00 ./ans_rproxy -f ./app.json myuser@ubsrv:/opt/ans/ans_rproxy$ sudo netstat -alntp | grep ans_rproxy | grep -v grep tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 4351/ans_rproxy tcp6 0 0 :::80 :::* LISTEN 4351/ans_rproxy myuser@ubsrv:/opt/ans/ans_rproxy$

11. 使用sudo調(diào)用root用戶權(quán)限，后臺(tái)方式啟動(dòng)ans_rproxy程序

myuser@ubsrv:/opt/ans/ans_rproxy$ sudo nohup ./ans_rproxy -f ./app.json > /dev/null 2>/dev/null & [1] 4143 myuser@ubsrv:/opt/ans/ans_rproxy$ myuser@ubsrv:/opt/ans/ans_rproxy$ sudo ps -waux | grep ans_rproxy | grep -v grep root 4143 0.0 0.1 52700 3936 pts/0 S 15:53 0:00 sudo nohup ./ans_rproxy -f ./app.json root 4144 0.0 0.0 9648 976 pts/0 S 15:53 0:00 ./ans_rproxy -f ./app.json rd_publ+ 4145 0.0 0.0 18096 1832 pts/0 S 15:53 0:00 ./ans_rproxy -f ./app.json myuser@ubsrv:/opt/ans/ans_rproxy$ sudo netstat -alntp | grep ans_rproxy | grep -v grep tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 4144/ans_rproxy tcp6 0 0 :::80 :::* LISTEN 4144/ans_rproxy myuser@ubsrv:/opt/ans/ans_rproxy$

12. 查看ans_rproxy進(jìn)程所占用的系統(tǒng)資源

myuser@ubsrv:/opt/ans/ans_rproxy$ sudo lsof -c ans_rproxy myuser@ubsrv:/opt/ans/ans_rproxy$

13. 測(cè)試訪問(wèn)ans_rproxy進(jìn)程提供的Session代理服務(wù)
業(yè)務(wù)測(cè)試必須使用客戶端瀏覽器進(jìn)行模擬用戶操作

14. 結(jié)束ans_rproxy進(jìn)程

myuser@ubsrv:/opt/ans/ans_rproxy$ sudo ps -waux | grep ans_rproxy | grep -v grep | awk '{print $2}' | sudo xargs kill -9 [1]+ Killed sudo nohup ./ans_rproxy -f ./app.json > /dev/null 2> /dev/null myuser@ubsrv:/opt/ans/ans_rproxy$ sudo ps -waux | grep ans_rproxy | grep -v grep myuser@ubsrv:/opt/ans/ans_rproxy$

15. 其他配置

安獅設(shè)備配置

注意：這里服務(wù)的監(jiān)視器類型必須是TCP類型,?使用HTTP類型的監(jiān)視器將會(huì)導(dǎo)致健康檢查失敗。

客戶端驗(yàn)證測(cè)試

1.?驗(yàn)證按權(quán)重值切換服務(wù)器

win1_50啟用web服務(wù), win2_53啟用web服務(wù)，用戶請(qǐng)求按權(quán)重比例分配給win1_50和win2_53服務(wù)器。

2.?驗(yàn)證服務(wù)器故障自動(dòng)切換

win1_50啟用web服務(wù), win2_53啟用web服務(wù)，此時(shí)進(jìn)行用戶登陸操作，操作頁(yè)面正常。
此時(shí)禁用win2_53的web服務(wù), 操作頁(yè)面正常，用戶請(qǐng)求自動(dòng)發(fā)送win1_50服務(wù)器。

3.?查看ans_rproxy進(jìn)程服務(wù)日志

FAQ:

1.?管理員賬戶密碼忘記時(shí)，可直接操作數(shù)據(jù)庫(kù)重置密碼。
