The Chinese language of the Linux system is garbled, which is a problem that many friends often encounter when they first come into contact with Linux. Moreover, when we move the projects that have been deployed in Wndows to run on Linux, the Chinese output logs of Tomcat are all garbled. (Normal on Windows), it looks very frustrating, so how should we solve it?
System Chinese garbled code
- CentOS 7.0 64-bit ##jdk-8u11-linux-x64.
- ##apache-tomcat-8.5. 16
## Solution steps:
1. Install the Chinese language pack
First check whether the Chinese language pack is installed on the system
locale -a (list the names of all available public locale environments)
machines in her in in in on in on in on in on in on in on the names in all available public locales What do several items mean?
{Language code}_{Country code}.{Character set}
zh is the code for Chinese, CN is the code for China, gb18030, gb2312, utf8 is the language character set
yum install kde-l10n-Chinese somehow 11M in about 11M
# Before modifying the configuration file, let’s take a look at the current system locale
("en_US.UTF-8" can be understood as "you speak English, you are in the United States, and the language character set is UTF-8" according to the above content)
Each item The meanings are:
LANG: The language of the current system LC_CTYPE: Language symbols and their classification
LC_NUMERIC: Numbers LC_COLLATE: Comparison and sorting Habit
LC_TIME: Time display format
Add the following two lines of code LANG="zh_CN.UTF-8"
LC_ALL="zh_CN.UTF-8"
# source /etc/sysconfig/i18n Modify the locale.cnf configuration file
# vim /etc/locale.conf
LANG="zh_CN.UTF-8"
## shall should should should be 10-100ml
##
####
#### Properties->Terminal (the terminal connection tool I use is Xshell. For other connection tools, please change the encoding method on Baidu)
Change the encoding to UTF-8
Reconnect and check the current system locale
Locale
It is found that the system locale has been successfully changed to "zh_CN.UTF-8"
Try editing Chinese again
# SUCCESS! At this point, the problem of garbled Chinese characters in the system has been solved. 4. Solve the problem of garbled Chinese characters in the Tomcat output log
Now that the Chinese garbled characters in the system have been solved, will the Chinese garbled characters in the Tomcat output log also be solved?
Let’s take a look at the Tomcat output log now
Enter the Tomcat directory
#, Tomcat log Chinese is still garbled.
Analysis: Since Chinese garbled characters no longer appear in the system, it proves that the system language environment is normal, but Chinese garbled characters still appear in the Tomcat log, indicating that it is an internal problem of Tomcat. I checked some information online and found that it is the JVM. (Java Virtual Machine)
The character set used by the Java virtual machine is inconsistent with the character set used by the system. If you know the reason, the problem will be solved. You can modify the JVM startup parameters by configuring the JVM startup parameters. Character set purpose.
# ls -l ./bin/
Find daemon.sh and catalina.sh and add the following codes respectively:
JAVA_OPTS= "$JAVA_OPTS -Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8 -Duser.language=zh_CN -Dsun.jnu.encoding=UTF-8"
# vim ./ bin/daemon.sh
# vim ./bin/catalina.sh
Save and exit, restart Tomcat # ./bin/shutdown.sh
# ./bin/startup.sh
Now check the output log
# tail -f ./ logs/catalina.out

centos7不带mysql数据库了,默认的数据库是mariadb(mysql的一个分支)。可以按照以下步骤手动安装mysql数据库。1.下载rpm安装文件wgethttp://repo.mysql.com/mysql-community-release-el7.rpm2.执行rpm安装rpm-ivhmysql-community-release-el7.rpm依赖解析完成后,出现下列选项:dependenciesresolved=================================

1、官网下载安装包选择适合linux的版本,这里选择最新的版本,下载到本地后上传到服务器或者centos下直接wget命令下载。切换到/usr/local目录,下载软件包#cd/usr/local#wgethttp://nginx.org/download/nginx-1.11.5.tar.gz2、安装nginx先执行以下命令,安装nginx依赖库,如果缺少依赖库,可能会安装失败,具体可以参考文章后面的错误提示信息。#yuminstallgcc-c++#yuminstallpcre#yumins

安装环境:Centos764位Jdk1.864位Xshell免费版win10*64位一、先进来,你需要检查自己的openjdk是否卸载(或者判断是否存在,因为一般centos都会预装openjdk):在xshell或rpm-qa|grepjdk中输入rpm-qa|grepjavarpm-qa|grepjava第二,如果有一个对应的openjdk,并且显示了一个响应列表,那么就需要卸载它。在xshell中输入rpm-e-nodepstzdata-文件名(这个文件名是你查看的openjdk文件列表中

Centos7修改系统时区的两种方法:1、使用timedatectl命令,可设定和修改时区信息,语法“timedatectl set-timezone 时区标识”;2、修改用户目录下的“.bash_profile”文件,在文件末尾追加“TZ='时区标识'; export TZ”即可。

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
