二、下载Tomcat
2.1 下载Tomcat
Tomcat官网 点击左侧的Download中的Tomcat 8: 选中右击后点击-复制链接地址 然后再服务器中使用wget命令下载Tomcat包
//链接修改成需要的版本
wget --no-check-certificate https://dlcdn.apache.org/tomcat/tomcat-8/v8.5.96/bin/apache-tomcat-8.5.93.tar.gz或者直接在浏览器中点击下载链接下载完成后再将apache-tomcat-8.5.93.tar.gz利用xftp等工具上传到服务器中。
2.2 解压并移动
//解压 apache-tomcat-8.5.93.tar.gz
tar -zxvf apache-tomcat-8.5.93.tar.gz//移动并改名到Tomcat目录
mv apache-tomcat-8.5.93 /usr/local/tomcat/移动并改名到Tomcat目录 在/usr/local/tomcat/目录下 bin存放Tomcat的一些脚本文件包含启动和关闭Tomcat服务脚本。 conf存放Tomcat服务器的各种全局配置文件其中最重要的是server.xml和web.xml。 webappsTomcat的主要Web发布目录默认情况下把Web应用文件放于此目录。 logs存放Tomcat执行时的日志文件。
2.3 创建一般用户
为保证系统安全性建议创建一般用户来运行Tomcat。
//创建一般用户djc
useradd djc//运行命令将文件的所属用户设置为djc
chown -R djc.djc /usr/local/tomcat/三、配置server.xml文件
//运行命令切换到/usr/local/tomcat/conf/目录。
cd /usr/local/tomcat/conf///运行以下命令重命名server.xml文件
//server.xml_bk相当于把server.xml初始文件的备份
mv server.xml server.xml_bk//新建一个server.xml文件
//会创建并打开一个server.xml文件
//i键编辑ESC键退出:wq保存并退出
vi server.xmlserver.xml的内容

#四、设置JVM内存参数
//运行命令创建并打开/usr/local/tomcat/bin/setenv.sh文件。
//i键编辑ESC键退出:wq保存并退出
vi /usr/local/tomcat/bin/setenv.sh//setenv.sh的内容
//指定JAVA_OPTS参数用于设置JVM的内存信息以及编码格式。
JAVA_OPTS-Djava.security.egdfile:/dev/./urandom -server -Xms256m -Xmx496m -Dfile.encodingUTF-8 cat setenv.sh:
四、设置Tomcat自启动脚本-Tomcat-init脚本
Tomcat-init
//获取Tomcat自启动脚本 Tomcat-init
//或者使用git clone从Windows里clone完成后再上传到linux服务器
//也可以在服务器中直接wget
wet https://github.com/oneinstack/oneinstack/blob/main/init.d/Tomcat-init//移动并重命名Tomcat-init
mv Tomcat-init /etc/init.d/tomcat//为/etc/init.d/tomcat添加可执行权限
chmod x /etc/init.d/tomcat//设置启动脚本JAVA_HOME
//重要:脚本中JDK的版本信息必须与您安装的JDK版本信息一致否则Tomcat会启动失败。

exit 0 上传自启动脚本Tomcat-init 注意这里的etc的init.d文件夹是个快捷方式链接 也就是说init.d实际指向rc.d下的init.d文件夹 里面有刚刚使用mv命令移动并重命名的Tomcat-init脚本文件即tomcat脚本文件 设置启动脚本JAVA_HOME 为/etc/init.d/tomcat添加可执行权限 (chmod x /etc/init.d/tomcat),字体变色变粗(可以用来识别命令是否生效)
五、启动Tomcat
//设置Tomcat开机自启动
chkconfig --add tomcat
chkconfig tomcat on//启动Tomcat
service tomcat start5.1 NO such file or directory
启动Tomcat: 报错tomcat-NO such file or directory: 这是因为Tomcat-init脚本文件也就是/etc/init.d/tomcat脚本文件 (之前执行了移动并重命名Tomcat-init脚本文件的命令mv Tomcat-init /etc/init.d/tomcat)这个文件中需要配置参数JAVA_HOME与TOMCAT_USERwww 修改为TOMCAT_USERdjc (TOMCAT_USER is the default user of tomcat)
所以此处的tomcat实际上是一个脚本文件的名称即Tomcat-init脚本文件。 cat tomcat脚本文件(即Tomcat-init脚本文件)

5.2 service tomcat start-command not found 原因shell脚本是在Windows下编写通过工具软件传输到CentOS中。而Windows下行结尾符号为\r\n linux下行结尾时\n两者不同所以无法识别需要转换一下。 参考我这篇文章CentOS: $‘\r‘: command not found
Tomcat-init脚本文件也就是/etc/init.d/tomcat脚本文件 (之前执行了移动并重命名Tomcat-init脚本文件的命令mv Tomcat-init /etc/init.d/tomcat)
所以此处的tomcat实际上是一个脚本文件的名称即Tomcat-init脚本文件内容见5.1 NO such file or directory 中的【修改后的tomcat脚本(即原来的Tomcat-init脚本mv Tomcat-init /etc/init.d/tomcat】
