centos-6.4 yum EPEL

标签：

初用centos，很多不习惯，记录一下。

首先装EPEL，不然默认的包少得可怜：（详见：http://www.rackspace.com/knowledge_center/article/install-epel-and-additional-repositories-on-centos-and-red-hat）

sudo yum install epel-release

 装完之后再用yum会报错：

[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

解决办法为：（详见：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，可以开始装别的东西了。。

OK，马上又碰到错误，装tmux唔得，解决如下 ：

1、系统自带libevent太低，要手动装2.0的：详见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

2、链接出错，要手动改Makefile加参数：详见：http://superuser.com/questions/829860/undefined-reference-to-b64-ntop-tmux-compilation-error-on-centos

　　错误：

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

　　解决：打开Makefiler找到【LIBS = -lutil -lcurses -levent -lrt】后面加-lresov

3、运行出错，要手动对依赖的so做软链：详见同上

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

 解决：

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