centos7安装部署JDK,tomcat

本文主要介绍java web常用开发生产环境的简单部署操作,后续持续更新

Centos7安装JDK，tomcat以及部署简单程序的操作说明

Centos7安装JDK

1. 在/usr/local下创建java文件夹

   cd /usr/local 
   mkdir java
   cd java

2. 将JDK文件拷贝到/usr/local/java下
   cp jdk-8u121-linux-x64.tar.gz /usr/local/java
tar -zxvf jdk-8u121-linux-x64.tar.gz
3. 设置环境变量
   vi /etc/profile，在文件末尾添加环境变量

   export JAVA_HOME=/usr/local/java/jdk1.8.0_121
   export JRE_HOME=/usr/local/java/jdk1.8.0_121/jre
   export PATH=$PATH:/usr/local/java/jdk1.8.0_121/bin
   export CLASSPATH=./:/usr/local/java/jdk1.8.0_121/lib:/usr/local/java/jdk1.8.0_121/jre/lib

   按 Esc 键、输入 :wq 回车，保持并退出。
   source /etc/profile 使配置生效
   输入javac/java/java -version测试使用正常

安装tomcat

1. 拷贝tomcat至/usr/local下

   cp apache-tomcat-7.0.75.tar.gz /usr/local 
   tar -xvzf apache-tomcat-7.0.75.tar.gz

2. 设置tomcat编码格式
   vi /apache-tomcat-7.0.75/conf/server.xml,增加URIEncoding参数配置

   <Connector port="8080" protocol="HTTP/1.1"
                  connectionTimeout="20000"
                  redirectPort="8443" URIEncoding="utf-8"/>

3. 常用命令

• 启动tomcat
  [root@localhost local]# ./apache-tomcat-7.0.75/bin/startup.sh
• 关闭tomcat
  [root@localhost local]# ./apache-tomcat-7.0.75/bin/shutdown.sh
• 查看日志
  tail -f catalina.out
• 查看tomcat进程
  ps -ef |grep tomcat

  ### mysql的配置
  vi /etc/my.cnf文件
  ```Ini
  [mysqld]
  datadir=/home/data/mysql
  socket=/home/data/mysql/mysql.sock
  lower_case_table_names=1
  # Disabling symbolic-links is recommended to prevent assorted security risks
  symbolic-links=0
  character_set_server = utf8
  default-storage-engine=INNODB
  # Recommended in standard MySQL setup
  sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,ONLY_FULL_GROUP_BY,STRICT_ALL_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER

修改sql_mode为最后一行的配置。

然后重启mysql

/etc/init.d/mysqld stop
/etc/init.d/mysqld restart

## 或者
service mysql stop
service mysql start
