centos-6.4 yum EPEL

初用centos，不少不習慣，記錄一下。

首先裝EPEL，否則默認的包少得可憐：（詳見：http://www.rackspace.com/knowledge_center/article/install-epel-and-additional-repositories-on-centos-and-red-hat）

sudo yum install epel-release

 裝完以後再用yum會報錯：

[root@cloud:~]yum search tmux

Loaded plugins: fastestmirror, refresh-packagekit, security

Loading mirror speeds from cached hostfile

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

解決辦法爲：（詳見：https://community.hpcloud.com/article/centos-63-instance-giving-cannot-retrieve-metalink-repository-epel-error）

sudo sed -i "s/mirrorlist=https/mirrorlist=http/" /etc/yum.repos.d/epel.repo

yum check-update

好了，能夠開始裝別的東西了。。

 

OK，立刻又碰到錯誤，裝tmux唔得，解決以下 ：

一、系統自帶libevent過低，要手動裝2.0的：詳見http://superuser.com/questions/738829/attempting-to-install-tmux-on-centos-6-4-or-centos-6-5-fails-with-error-evbuff

wget http://iweb.dl.sourceforge.net/project/levent/libevent/libevent-2.0/libevent-2.0.22-stable.tar.gz
tar -xvzf libevent-2.0.22-stable.tar.gz
cd libevent-2.0.22-stable
./configure
make
make install

二、連接出錯，要手動改Makefile加參數：詳見：http://superuser.com/questions/829860/undefined-reference-to-b64-ntop-tmux-compilation-error-on-centos

　　錯誤：

.../tty.c:1067: undefined reference to `__b64_ntop'

　　解決：打開Makefiler找到【LIBS = -lutil -lcurses -levent -lrt】後面加-lresov

三、運行出錯，要手動對依賴的so作軟鏈：詳見同上

tmux: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

 解決：

sudo ln -s /usr/local/lib/libevent-2.0.so.5 /lib64/

真是蛋疼。。。
