参数说明：
org.apache.coyote.http11.Http11NioProtocol：调整工作模式为Nio
有三种工作模式：Bio、Nio和Apr
Bio(Blocking I/O)：默认工作模式，阻塞式I/O操作，没有任何优化技术处理，性能比较低。
Nio(New I/O or Non-Blocking)：非阻塞式I/O操作，有Bio有更好的并发处理性能。
Apr(Apache Portable Runtime，Apache可移植运行库)：首选工作模式，主要为上层的应用程序提供一个可以跨越多操作系统平台使用的底层支持接口库。
tomcat利用基于Apr库tomcat-native来实现操作系统级别控制，提供一种优化技术和非阻塞式I/O操作，大大提高并发处理能力。但是需要安装apr和tomcat-native库。

maxThreads：最大线程数，默认150。增大值避免队列请求过多，导致响应缓慢。
minSpareThreads：最小空闲线程数。
maxSpareThreads：最大空闲线程数，如果超过这个值，会关闭无用的线程。
acceptCount：当处理请求超过此值时，将后来请求放到队列中等待。
disableUploadTimeout：禁用上传超时时间
connectionTimeout：连接超时，单位毫秒，0代表不限制
URIEncoding：URI地址编码使用UTF-8
enableLookups：关闭dns解析，提高响应时间
compression：启用压缩功能
compressionMinSize：最小压缩大小，单位Byte
compressableMimeType：压缩的文件类型

调整JVM内存大小：
在catalina.sh增加JAVA_OPTS=’-Xms512m -Xmx1024m -XX:PermSize=128m-XX:MaxPermSize=256m’
-Xms JVM初始最小堆内存，默认为物理内存1/64，不要设置过大，否则增加回收时间（暂停应用），相对频率少，相反，频率高。
-Xmx JVM最大允许堆内存大小，默认为物理内存1/4
-XX:PermSize JVM初始分配非堆内存大小
-XX:MaxPermSize JVM最大允许分配的非堆内存

一. if的基本语法

  1. if与[之间要有空格
  2. []与判断条件之间也必须有空格
  3. ]与;之间不能有空格

二. 对字符串的判断

  1. if [ str1=str2 ];then fi #当两个字符串相同时返回真
  2. if [ str1!=str2 ];then fi #当两个字符串不相等时返回真
  3. if [ -n str1 ];then fi #当字符串的长度大于0时返回真 (判断变量是否有值)
  4. if [ -z str1 ];then fi #当字符串的长度为0时返回真

三. 对数字的判断

  1. int1 -eq int2 #int1和int2相等
  2. int1 -ne int2 #int1不相等int2
  3. int1 -gt int2 #int1大于int2
  4. int1 -ge int2 #int1大于等于int2
  5. int1 -lt int2 #int1小于int2
  6. int1 -le int2 #int1小于等于int2

四. 对文件属性的判断

  1. -r file #用户可读为真
  2. -w file #用户可写为真
  3. -x file #用户可执行为真
  4. -f file #文件存在且为正规文件为真
  5. -d file #如果是存在目录为真
  6. -c file #文件存在且为字符设备文件
  7. -b file #文件存在且为块设备文件
  8. -s file #文件大小为非0为真，可以判断文件是否为空
  9. -e file #如果文件存在为真

五. 逻辑判断

  1. -a #与
  2. -o #或
  3. ! #非

1.首先到Maven官网下载安装文件，目前最新版本为3.3.9，下载文件为apache-maven-3.3.9-bin.tar.gz，下载可以使用wget命令；

1
wget http://apache.fayea.com/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz

2.进入下载文件夹，找到下载的文件，运行如下命令解压

1
tar -xvf  apache-maven-3.3.9-bin.tar.gz

解压后的文件夹名为apache-maven-3.3.9

3.使用mv命令将apache-maven-3.3.9文件夹拷贝到自己指定的文件夹，比如/usr/local/下

1
mv -rf apache-maven-3.3 /usr/local/

4.配置环境变量，编辑/etc/profile文件，添加如下代码

1
2
3
MAVEN_HOME=/usr/local/apache-maven-3.3.9
export MAVEN_HOME
export PATH=${PATH}:${MAVEN_HOME}/bin

5.保存文件，并运行如下命令使环境变量生效
source /etc/profile

6.在控制台输入如下命令，如果能看到Maven相关版本信息，则说明Maven已经安装成功
mvn -v
