使用salt集中安装/配置/管理Tomcat
首先我们有2台机器需要部署tomcat如下：
[root@mysqlhost ~]# salt-key -L Accepted Keys: 192.168.137.154 192.168.137.155 Unaccepted Keys: Rejected Keys:
查看2台机器OS版本
[root@mysqlhost ~]# salt '*' cmd.run "uname -a;cat /etc/redhat-release"
192.168.137.155:
Linux mysqlhost 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
Red Hat Enterprise Linux Server release 6.0 (Santiago)
192.168.137.154:
Linux rhl6.0x64 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
Red Hat Enterprise Linux Server release 6.0 (Santiago)
查看2台机器磁盘信息
[root@mysqlhost ~]# salt '*' cmd.run "df -h"
192.168.137.154:
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 36G 15G 20G 43% /
tmpfs 1.9G 204K 1.9G 1% /dev/shm
/dev/sda1 194M 30M 155M 16% /boot
192.168.137.155:

/dev/sda3 36G 7.0G 27G 21% /
tmpfs 1.9G 0 1.9G 0% /dev/shm
/dev/sda1 194M 30M 155M 16% /boot
我们在根目录下建一个tomcat目录
[root@mysqlhost ~]# salt '*' cmd.run "mkdir -p /tomcat"
192.168.137.155:
192.168.137.154:
将安装介质放到指定目录并解压
[root@mysqlhost ~]# salt-cp '*' /tmp/apache-tomcat-8.0.12.tar.gz /tomcat/apache-tomcat-8.0.12.tar.gz
{}
注意：在传输大文件时会超时报错
[root@mysqlhost ~]# salt '*' cmd.run "cd /tomcat;tar -zxvf apache-tomcat-8.0.12.tar.gz"
[root@mysqlhost ~]# salt '*' cmd.run "ls -ltr /tomcat"
192.168.137.155:
total 9004
-rw-r--r--. 1 root root 9212991 Sep 4 04:36 apache-tomcat-8.0.12.tar.gz
drwxr-xr-x. 9 root root 4096 Sep 4 04:37 apache-tomcat-8.0.12
192.168.137.154:
total 9004
-rw-r--r--. 1 root root 9212991 Aug 14 16:53 apache-tomcat-8.0.12.tar.gz
drwxr-xr-x. 9 root root 4096 Aug 14 16:55 apache-tomcat-8.0.12
配置环境变量
[root@mysqlhost ~]# salt '*' cmd.run "echo JAVA_HOME=/usr/java/jdk1.7.0_25 >> /etc/profile"
[root@mysqlhost ~]# salt '*' cmd.run "echo CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib >> /etc/profile"
[root@mysqlhost ~]# salt '*' cmd.run "echo PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin >> /etc/profile"
[root@mysqlhost ~]# salt '*' cmd.run "echo export PATH CLASSPATH JAVA_HOME >> /etc/profile"
[root@mysqlhost ~]# salt '*' cmd.run "source /etc/profile;tail -4 /etc/profile"
192.168.137.154:
JAVA_HOME=/usr/java/jdk1.7.0_25
CLASSPATH=/lib:/jre/lib
PATH=/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/u01/mysql/bin:/root/bin:/bin:/jre/bin
export PATH CLASSPATH JAVA_HOME
192.168.137.155:
JAVA_HOME=/usr/java/jdk1.7.0_25
CLASSPATH=/lib:/jre/lib
PATH=/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/u01/mysql/bin:/root/bin:/bin:/jre/bin
export PATH CLASSPATH JAVA_HOME
将tomcat添加到系统服务中
salt '*' cmd.run "cp /tomcat/apache-tomcat-8.0.12/bin/catalina.sh /etc/init.d/Tomcat" salt '*' cmd.run "sed -i '2i\#chkconfig: 2345 10 90' /etc/init.d/Tomcat" salt '*' cmd.run "sed -i '3i\#description:Tomcat service' /etc/init.d/Tomcat" salt '*' cmd.run "sed -i '4i\JAVA_HOME=/usr/java/jdk1.7.0_25' /etc/init.d/Tomcat" salt '*' cmd.run "sed -i '5i\CATALINA_HOME=/tomcat/apache-tomcat-8.0.12' /etc/init.d/Tomcat" salt '*' cmd.run "chkconfig --add Tomcat" salt '*' cmd.run "service Tomcat stop" salt '*' cmd.run "service Tomcat start"
获取当前运行tomcat的版本信息
[root@mysqlhost salt]# salt '*' cmd.run "service Tomcat version"

测试集中管理
目前154的机器的tomcat运行在默认的8080端口
[root@mysqlhost tomcat]# telnet 192.168.137.154 8084 Trying 192.168.137.154... telnet: connect to address 192.168.137.154: Connection refused [root@mysqlhost tomcat]# telnet 192.168.137.154 8080 Trying 192.168.137.154... Connected to 192.168.137.154. Escape character is '^]'. ^] telnet> q Connection closed.
我们在集中管理端将tomcat配置文件server.xml的默认端口从8080改为8084
<Connector port="8084" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
