Step 1：切换至字体下载目录：
[Richard@localhost Downloads]$ ll | grep otf -rw-rw-r--. 1 Richard Richard 16676 7月 19 2011 RBNo2Light_a.otf -rw-rw-r--. 1 Richard Richard 17912 7月 19 2011 RBNo2Light.otf
Step 2：切换至root用户：
[Richard@localhost Downloads]$ su 密码： [root@localhost Downloads]#
Step 3：新建/usr/share/fonts/default/TrueType目录
[root@localhost Downloads]# mkdir /usr/share/fonts/default/TrueType
Step 4：把字体拷贝到新建的目录下
[root@localhost Downloads]# cp RBNo2Light*.otf /usr/share/fonts/default/TrueType/
Step 5：切换至字体所在目录
[root@localhost Downloads]# cd /usr/share/fonts/default/TrueType/
Step 6：创建fonts.scale
[root@localhost TrueType]# ll 总用量 40 -rw-r--r--. 1 root root 16676 12月 1 20:59 RBNo2Light_a.otf -rw-r--r--. 1 root root 17912 12月 1 20:59 RBNo2Light.otf [root@localhost TrueType]# ttmkfdir [root@localhost TrueType]# ll 总用量 44 -rw-r--r--. 1 root root 2 12月 1 21:00 fonts.scale -rw-r--r--. 1 root root 16676 12月 1 20:59 RBNo2Light_a.otf -rw-r--r--. 1 root root 17912 12月 1 20:59 RBNo2Light.otf
Step 7：创建fonts.dir
[root@localhost TrueType]# mkfontdir [root@localhost TrueType]# ll 总用量 48 -rw-r--r--. 1 root root 2 12月 1 21:00 fonts.dir -rw-r--r--. 1 root root 2 12月 1 21:00 fonts.scale -rw-r--r--. 1 root root 16676 12月 1 20:59 RBNo2Light_a.otf -rw-r--r--. 1 root root 17912 12月 1 20:59 RBNo2Light.otf
Step 8： 将字体路径添加到X Font serve 路径(或者[root@localhost Downloads]# /usr/sbin/chkfontpath --add /usr/share/fonts/default/TrueType)：
[root@localhost TrueType]# chkfontpath --add /usr/share/fonts/default/TrueType
Step 9：更新字体信息cache
[root@localhost TrueType]# fc-cache
Step 10：查看字体
[Richard@localhost Downloads]$ fc-list :lang=en | grep RB /usr/share/fonts/default/TrueType/RBNo2Light.otf: RBNo2 Light:style=Regular /usr/share/fonts/default/TrueType/RBNo2Light_a.otf: RBNo2 Light Alternative :style=Regular
备注：如果没有chkfontpath，则安装chkfontpath（chkfontpath依赖xfs），安装方法如下：
Step 1： http://rpm.pbone.net/index.php3/stat/4/idpl/13943722/dir/centos_5/com/chkfontpath-1.10.1-1.1.x86_64.rpm.html下载chkfontpath-1.10.1-1.1.x86_64.rpm，然后安装。
Step 2：rpm安装chkfontpath（可能缺少依赖）
[Richard@localhost Downloads]$ chmod +x chkfontpath-1.10.1-1.1.x86_64.rpm [Richard@localhost Downloads]$ sudo rpm -ivh chkfontpath-1.10.1-1.1.x86_64.rpm [sudo] password for Richard: 警告：chkfontpath-1.10.1-1.1.x86_64.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID e8562897: NOKEY 错误：依赖检测失败： xfs 被 chkfontpath-1.10.1-1.1.x86_64 需要
Step 3：安装xfs依赖
[Richard@localhost Downloads]$ sudo yum install xfs 已加载插件：fastestmirror, langpacks, refresh-packagekit Repository updates is listed more than once in the configuration Repository updates-debuginfo is listed more than once in the configuration Repository updates-source is listed more than once in the configuration Repository updates is listed more than once in the configuration Repository updates-debuginfo is listed more than once in the configuration Repository updates-source is listed more than once in the configuration Repository fedora is listed more than once in the configuration Repository fedora-debuginfo is listed more than once in the configuration Repository fedora-source is listed more than once in the configuration Repository fedora is listed more than once in the configuration Repository fedora-debuginfo is listed more than once in the configuration Repository fedora-source is listed more than once in the configuration Loading mirror speeds from cached hostfile * fedora: mirrors.163.com * rpmfusion-free-rawhide: ftp.sjtu.edu.cn * rpmfusion-nonfree-rawhide: mirrors.163.com * updates: mirrors.163.com 正在解决依赖关系 --> 正在检查事务 ---> 软件包 xorg-x11-xfs.x86_64.1.1.1.2-4.fc20 将被 安装 --> 解决依赖关系完成 依赖关系解决 ================================================================================ Package 架构 版本 源 大小 ================================================================================ 正在安装: xorg-x11-xfs x86_64 1:1.1.2-4.fc20 fedora 75 k 事务概要 ================================================================================ 安装 1 软件包 总下载量：75 k 安装大小：136 k Is this ok [y/d/N]: y Downloading packages: xorg-x11-xfs-1.1.2-4.fc20.x86_64.rpm | 75 kB 00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction (shutdown inhibited) 正在安装 : 1:xorg-x11-xfs-1.1.2-4.fc20.x86_64 1/1 验证中 : 1:xorg-x11-xfs-1.1.2-4.fc20.x86_64 1/1 已安装: xorg-x11-xfs.x86_64 1:1.1.2-4.fc20 完毕！
Step 4：使用RPM安装chkfontpath：
[Richard@localhost Downloads]$ sudo rpm -ivh chkfontpath-1.10.1-1.1.x86_64.rpm 警告：chkfontpath-1.10.1-1.1.x86_64.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID e8562897: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:chkfontpath-1.10.1-1.1 ################################# [100%] [Richard@localhost Downloads]$
