【测试】华为 openEuler 镜像适应性测试（续1）
1. 系统中文乱码问题
上一篇文章中我忘记了说一下我使用的 openEuler 镜像版本了，如下图所示：
docker pull openeuler/openeuler:22.03-lts-sp2
这个镜像有一个问题…不支持中文，如下图所示：
[root@chain30 ~]# docker run -it openeuler/openeuler:22.03-lts-sp2 /bin/bash
Welcome to 3.10.0-862.el7.x86_64
System information as of time: Thu Jul 27 06:23:08 UTC 2023

[root@d155f55f1587 /]# mkdir 这是一个文件夹
[root@d155f55f1587 /]# ls
afs dev home lib64 mnt proc run srv tmp var
bin etc lib media opt root sbin sys usr ''$'\350\277\231\344\346\230\257\344\270\200\344\270\252\346\226\207\344\273\266\345\244\271'
[root@d155f55f1587 /]#
我们先通过“locale”看看系统的字符集配置。如下图：
[root@d155f55f1587 /]# locale
LANG=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=
之后我们又实用“locale -a”命令看看目前支持那些字符集，如下图：
[root@d155f55f1587 /]# locale -a
C
C.utf8
POSIX
这…有C.utf8其实就是支持中文的呀，这个乱码问题只需要将原来的 POSIX 改为 C.utf8 就可以了。这就需要我们再修改一下 vi ~/.bashrc，使中文支持生效
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
export LC_ALL=C.utf8
export LANG=C.utf8
这里为什么不写在 /etc/profile 里面呢？这是因为我们使用的是镜像，写在 profile 里在重启容器后配置将不会生效，难道每次重启都要执行一次 source /etc/profile 么，既然这样还不如写在 .bashrc 文件里面。在编写完成后，我们就可以使用 exit 退出容器，然后通过 docker commit 打包一个新的镜像出来，之后再启动那个新镜像。如下图：
[root@d155f55f1587 /]# exit
exit
[root@chain30 ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d155f55f1587 openeuler/openeuler:22.03-lts-sp2 "/bin/bash" 31 minutes ago Exited (0) 3 seconds ago suspicious_euler
[root@chain30 ~]# docker commit d155f55f1587 euler-tmp:v1
sha256:9eec5db71c33d2713fb9fd336624c48dc737499fd8103c4462fda955725038a1
之后进入到新容器内部 mkdir 一个中文文件夹来验证一下，如下图：
[root@c8c7a83afabc /]# echo $LANG
C.utf8
[root@c8c7a83afabc /]# locale
LANG=C.utf8
LC_CTYPE="C.utf8"
LC_NUMERIC="C.utf8"
LC_TIME="C.utf8"
LC_COLLATE="C.utf8"
LC_MONETARY="C.utf8"
LC_MESSAGES="C.utf8"
LC_PAPER="C.utf8"
LC_NAME="C.utf8"
LC_ADDRESS="C.utf8"
LC_TELEPHONE="C.utf8"
LC_MEASUREMENT="C.utf8"
LC_IDENTIFICATION="C.utf8"
LC_ALL=C.utf8
[root@c8c7a83afabc /]# ls
afs bin dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var
[root@c8c7a83afabc /]# mkdir 我是文件夹
[root@c8c7a83afabc /]# ls
afs bin dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var 我是文件夹
2. java 项目验证码无法输出
有同事反映说，使用新镜像后原通过 redis 生成的 captcha 验证码出现无法输出的情况，如下图：
...

...
通过 java 的输出看到报错的原因是找不到 sun.font.SunFontManager 类。看上去就是跟字体的支持有关，那么先安装字体库吧。如下图：
[root@9bdec7fad99d home]# yum install fontconfig

Complete!
之后再进行调用就可以了，如下图：
