Ubuntu 服务器配置
1. 停用Ubuntu默认的防火墙服务 ( Ubuntu防火墙服务名称为: 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. 上传部署文件
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. 设置ans_rproxy程序的动态链接库路径
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程序所需的动态链接库是否存在
若使用系统提供的库 libev.so.4 , 可以安装执行命令安装对应的库文件 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用户
备注: Centos 的删除用户命令( userdel -fr rd_public )和添加用户命令( 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. 创建工作目录/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: 默认日志文件 在 Ubuntu 上为 /var/log/syslog 在 CentOS 上为 /var/log/messages
添加的虚拟服务器列表的权重值相加的和一定要为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. 测试服务器是否可以正常访问
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

Date: Mon, 17 Sep 2018 08:29:26 GMT myuser@ubsrv:/opt/ans/ans_rproxy$
myuser@ubsrv:/opt/ans/ans_rproxy$ curl -I http://172.16.204.53:8081/LoginFuZai.aspx

Date: Mon, 17 Sep 2018 08:29:34 GMT myuser@ubsrv:/opt/ans/ans_rproxy$
9. 使用rd_public用户启动ans_rproxy程序
注意：这里启动会报错，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.

myuser@ubsrv:/opt/ans/ans_rproxy$
10. 使用sudo调用root用户权限，启动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.

11. 使用sudo调用root用户权限，后台方式启动ans_rproxy程序
myuser@ubsrv:/opt/ans/ans_rproxy$ sudo nohup ./ans_rproxy -f ./app.json > /dev/null 2>/dev/null &
[1] 4143

tcp6 0 0 :::80 :::* LISTEN 4144/ans_rproxy
myuser@ubsrv:/opt/ans/ans_rproxy$
12. 查看ans_rproxy进程所占用的系统资源
myuser@ubsrv:/opt/ans/ans_rproxy$ sudo lsof -c ans_rproxy
myuser@ubsrv:/opt/ans/ans_rproxy$
13. 测试访问ans_rproxy进程提供的Session代理服务
业务测试必须使用客户端浏览器进行模拟用户操作
myuser@ubsrv:/opt/ans/ans_rproxy$ curl -v http://localhost:80/LoginFuZai.aspx

客户端验证测试
1. 验证按权重值切换服务器
win1_50启用web服务, win2_53启用web服务，用户请求按权重比例分配给win1_50和win2_53服务器。
2. 验证服务器故障自动切换
win1_50启用web服务, win2_53启用web服务，此时进行用户登陆操作，操作页面正常。
此时禁用win2_53的web服务, 操作页面正常，用户请求自动发送win1_50服务器。
3. 查看ans_rproxy进程服务日志
FAQ:
1. 管理员账户密码忘记时，可直接操作数据库重置密码。
