需求背景

centos7 下 JAVA 生成圖片水印時中文亂碼，原因是沒有安裝中文字體。

安裝中文字體

以下是基于 Centos7 手動安裝中文字體的詳細步驟。當測試或者生產環境服務器比較多的時候，建議使用自動化運維工具。

# 安裝字體庫
$ yum -y install fontconfig

# 查看是否有中文字體
$ fc-list :lang=zh

# 創建中文字體目錄
$ mkdir /usr/share/fonts/chinese

# 在 windows 的 C:WindowsFonts 目錄下找到相應的字體 copy 到 chinese 目錄下，這里以 宋體 為例
$ scp simsun.ttc simsunb.ttf root@xxxxx:/usr/share/fonts/chinese

# 查看是否有中文字體
$ fc-list :lang=zh
/usr/share/fonts/chinese/simsun.ttc: SimSun,宋體:style=Regular,常規
/usr/share/fonts/chinese/simsun.ttc: NSimSun,新宋體:style=Regular,常規

Ansible 批量安裝

通常測試或者生產環境服務器比較多，下面記錄如何使用 Ansbile 來批量安裝中文字體。

# ansbile playbook 執行
$ ansible-playbook fonts.yml

# 驗證所有服務器是否生效
$ ansible all -m shell -a "fc-list :lang=zh"
sever01 | SUCCESS | rc=0 >>
/usr/share/fonts/chinese/simsun.ttc: SimSun,宋體:style=Regular,常規
/usr/share/fonts/chinese/simsun.ttc: NSimSun,新宋體:style=Regular,常規
sever02 | SUCCESS | rc=0 >>
/usr/share/fonts/chinese/simsun.ttc: SimSun,宋體:style=Regular,常規
/usr/share/fonts/chinese/simsun.ttc: NSimSun,新宋體:style=Regular,常規
