Docker install Trojan-go Xray

方法一：选择时区 1.执行命令： dpkg-reconfigure tzdata 2.选择Asia->Shanghai 防止系统重启后时区改变，执行下面一行命令 cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime 参考处处： 作者：Leon_Geo 链接：https://www.jianshu.com/p/ef851a01d9de ================== Trojan-go SETUP ======================

UBNT_ERX 路由器开启ipv6

Config Tree -> firewall / options / mss-clamp6 一般标准的 PPPoE 环境 IPv6 MSS 值应该是 1432 (1500-8-40-20)， 如果设成1432还是有问题可以再改小试试，有人曾改到 1382 才可以。 interfaces/ethernet/eth0/pppo/0/dhcpv6-pd/pd/0/interface，如果只用1个ip段的内网，就设定 host-address为::1 prefix-id为:1（因为有2个内网段192.168.1.x和192.168.2.x) service为slaac。 上面的步骤到点开pd/0后显示/64，把/64改成/60，不会报错了 interfaces / ethernet / eth0 / pppoe / 0 / ipv6 / address，点+ interfaces / ethernet / eth0 / pppoe / 0 / ipv6 / enable，点+ 以上设置完成后Preview即可生效，如果ipv6 DNS服务器经常抽风，导致打开网页最开始会很卡，可以在IPv6里面启用no-dns选项。 如果运营商给的地址是/64，没有DHCPv6-PD，可以通过IPv6 NDP解决，OpenWRT实现的外网网卡是eth0，内网是br-lan，先安装ndppd

$ sudo service apache2 restart Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details.

手贱，想解决ssl 无法访问的问题，修改apache2配置，结果出问题了：

$ sudo service apache2 restart
Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details.

虽然找到了许多网友的解决办法，但是没有一个全套解决办法，只好耐心一个合着试验，
最终解决了。
1、重新安装apache2

$ systemctl restart apache2
$ journal -xe 
$ sudo apt-get purge apache2
$ sudo apt autoremove apache2
$ sudo apt-get purge apache2
$ sudo apt-get purge apache2*
$ sudo apt-get install apache2
$ sudo service apache2 start

2、重点在这里：
重新安装了apache2，网站正常访问了，但是php却无法正常运行，
问题是这个
php7.3没有运行，
所以：sudo  a2enmod php7.3
但是出现如下提示：
Considering dependency mpm_prefork for php7.3:
Considering conflict mpm_event for mpm_prefork:
ERROR: Module mpm_event is enabled - cannot proceed due to conflicts. It needs to be disabled first!
Considering conflict mpm_worker for mpm_prefork:
ERROR: Could not enable dependency mpm_prefork for php7.3, aborting

所以接着：
sudo a2dismod mpm_event
Module mpm_event disabled.
To activate the new configuration, you need to run:
  systemctl restart apache2

OK，解决了

installing boost 166

issue：

 # cmake .. -DENABLE_MYSQL=OFF -DENABLE_SSL_KEYLOG=ON -DFORCE_TCP_FASTOPEN=ON -DSYSTEMD_SERVICE=AUTO

CMake Error at /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):

  Could NOT find Boost: Found unsuitable version "1.65.1", but required is at

  least "1.66.0" (found /usr/include)

Call Stack (most recent call first):

  /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:391 (_FPHSA_FAILURE_MESSAGE)

-- Configuring incomplete, errors occurred!

See also "/root/trojan/build/CMakeFiles/CMakeOutput.log".

See also "/root/trojan/build/CMakeFiles/CMakeError.log".

1. Download Boost from official source
2. Extract it
3. Open terminal and cd to extracted dir
4. run "./bootstrap.sh --help" command to see help
5. Then run "./bootstrap.sh" command it will take some time to build
6. Then run "sudo ./b2 install" to install boost.
7. The default installation location are "/usr/local/inlcude/boost" for header files and "/usr/local/lib" for compiled libraries

Fedora iptable firewalld selinux

Fedora server 30 默认开启了iptables，造成我安装各种httpd、plexmediaserver等，均无法从远程登陆，无法设置端口，因此我处理如下：
systemctl stop firewalld dnf install iptables-services

重启系统

systemctl restart iptables
systemctl stop iptables

然后iptables -L -n，显示如下：
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

这样，就可以放心使用firewalld
