生产环境:

Server version: Apache Tomcat/8.5.16
CentOS Linux release 7.3.1611 (Core) x86-64

1.Apache Tomcat/8.5.16依赖jre7及以上版本，不过jdk高版本已经包含jre，关于jdk&jre的安装请查看《Linux JAVA JDK JRE 环境变量安装与配置》

2.创建tomcat专有用户

# groupadd tomcat
# useradd -g tomcat -s /bin/false tomcat
或
# useradd -g tomcat -s /sbin/nologin tomcat

注意：

-g tomcat用户隶属于tomcat组
-s /bin/false 禁用shell访问

3.Apache Tomcat 8.5下载安装与配置&设置用户组权限并创建软连接

# cd /tmp
# wget //apache.fayea.com/tomcat/tomcat-8/v8.5.16/bin/apache-tomcat-8.5.16.tar.gz
# tar zxvf apache-tomcat-8.5.16.tar.gz
# mv apache-tomcat-8.5.16 /usr/local/
# cd /usr/local/
# chown -hR tomcat:tomcat apache-tomcat-8.5.16
# ln -s apache-tomcat-8.5.16 tomcat

4.添加tomcat自启动systemd服务单元文件

# vim /lib/systemd/system/tomcat.service

[Unit]
Description=Apache Tomcat 8
After=syslog.target network.target

[Service]
Type=forking
User=tomcat
Group=tomcat

Environment=JAVA_HOME=/usr/local/jdk/jre
Environment=CATALINA_PID=/usr/local/tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/usr/local/tomcat
Environment=CATALINA_BASE=/usr/local/tomcat
Environment='CATALINA_OPTS=-Xms512M -Xmx4096M -server -XX:+UseParallelGC'
Environment='CATALINA_OPTS=-Dfile.encoding=UTF-8 -server -Xms2048m -Xmx2048m -Xmn1024m -XX:SurvivorRatio=10 -XX:MaxTenuringThreshold=15 -XX:NewRatio=2 -XX:+DisableExplicitGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'

ExecStart=/usr/local/tomcat/bin/startup.sh
ExecStop=/bin/kill -15 $MAINPID
Restart=on-failure

[Install]
WantedBy=multi-user.target

5.重载systemd服务单元，给予软连接目录权限，启动Apache Tomcat服务并设置Tomcat为开机自启动

# systemctl daemon-reload
# cd /usr/local/
# chown -hR tomcat:tomcat tomcat
# systemctl start tomcat
# systemctl enable tomcat

6.配置Apache Tomcat用户实现远程登录

在tomcat-users.xml文件<tomcat-users></tomcat-users>中间添加；

# vim /usr/local/tomcat/conf/tomcat-users.xml
<role rolename="manager-gui"/>
<user username="tomcat" password="s3cret" roles="manager-gui"/>

tomcat8.5之后的版本，已经增强远程登录安全过滤规则，默认不支持远程登录，需要修改配置文件。

修改文件:

/host-manager/META-INF/context.xml
/manager/META-INF/context.xml

默认值:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
 allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />

修改为:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
 addConnectorPort="true"
 allow="127\.\d+\.\d+\.\d+;\d*|::1;\d*|0:0:0:0:0:0:0:1;\d*|.*;8080"/>

详情可查看 Valve 文档

7.配置Firewalld防火墙

如果不放行8080端口，就无法在外部使用8080进行访问，现在将端口放行并重载firewall服务

# firewall-cmd --zone=public --add-port=8080/tcp --permanent
# firewall-cmd --reload
# firewall-cmd --list-ports
# firewall-cmd --list-services

目前为止Apache Tomcat 8.5.16已经成功安装。现在您可以使用IP:port进行测试访问。
