This is a small guide on installing tShock and Mono on CentOS 6.5, I had some issues getting things going with this distro (and specific version) since the install of Mono is fairly scarce. But this will help those that are seeming to try and use it themselves too. Installing Mono To start, lets install Mono first. As of posting this guide, this will install Mono 3.4.0. Open /etc/yum.repo.d/mono.repoin your favorite editor. The file probably does not exist you need to create it! Add the following text to the above file: Code: [home_tpokorra_mono] name=mono and monodevelop (CentOS_CentOS-6) type=rpm-md baseurl=http://download.opensuse.org/repositories/home:/tpokorra:/mono/CentOS_CentOS-6/ gpgcheck=1 gpgkey=http://download.opensuse.org/repositories/home:/tpokorra:/mono/CentOS_CentOS-6/repodata/repomd.xml.key enabled=1 Save the file and exit your editor. Run an update on yum first before we try to install anything via: yum update Next, lets install the needed Mono packages with: yum install mono-*opt Accept any downloads it requires and such, you should only need to say yes to 1 prompt. Next we need to register executables to the binfmt via the following command: echo ':CLR:M::MZ::/usr/local/bin/mono:' > /proc/sys/fs/binfmt_misc/register Next we need to adjust our PATH variable. I personally edit the .bashrc file for this. Open ~/.bashrc in your favorite editor. Near the top (above the current alias' if any) add the following line: export PATH=/opt/mono/bin:$PATH Mono should now be installed and working. You can type mono --version to print out the version info. Installing tShock Installing tShock is very straight forward. Go to the following to get the latest package link: https://github.com/NyxStudios/TShock/releases/latest As of this post the latest is: https://github.com/NyxStudios/TShock/releases/download/v4.21104/TShock.for.22.214.171.124.zip Next create a folder for tShock, I recommend in your /home/ folder: mkdir /home/tshock Next go into the folder and obtain the latest package of tShock with wget: cd /home/tshock wget https://github.com/NyxStudios/TShock/releases/download/v4.21104/TShock.for.126.96.36.199.zip Next we need to unzip the file: unzip TShock.for.188.8.131.52.zip Done, tShock is installed. Running tShock Next, to run tShock we do the following: cd /home/tshock mono TerrariaServer.exe And that is it. tShock should start without issue. Help, my map does not show up! Players just fall endlessly! This is due to missing libs. Shutdown your server and run the following command: find / -name libMonoPosixHelper.so This should locate the library within 1 or more directories. For example like this: [[email protected] /]# find / -name libMonoPosixHelper.so /opt/mono/lib/libMonoPosixHelper.so /usr/local/src/mono-3.4.0/support/.libs/libMonoPosixHelper.so [[email protected] /]# We need to add the /opt/mono/lib folder to our environment variables library path. To do that, do the following: Open ~/.bashrc in your favorite editor. Locate were we added export PATH and under that add: export LD_LIBRARY_PATH=/opt/mono/lib:$LD_LIBRARY_PATH Be sure to change the /opt/mono/lib to the folder that was found in your find results!
