部署jenkins,采用普通用户tomcat来启动tomcat服务

Posted 2020-10-31

安装jdk+tomcat,部署jenkins,采用普通用户tomcat来启动tomcat服务

1.环境说明

CentOS Linux release 7.3.1611 (Core)
jdk1.8.0_60
apache-tomcat-8.5.23

已经安装好

2.编译安装服务守护程序

cd /usr/local/apache-tomcat-8.5.23/bin/
tar xf commons-daemon-native.tar.gz
cd /usr/local/apache-tomcat-8.5.23/bin/commons-daemon-1.0.15-native-src/unix/
 ./configure

如果编译过程中出现如下错误提示，说明未设置JAVA_HOME变量：

 Java compilation tools 
checking for JDK location... configure: error: Java Home not defined. Rerun with --with-java=... parameter

可以通过命令行参数指定JDK位置
./configure --with-java=/usr/local/jdk1.8.0_60

配置成功后，开始编译。

make
执行make后会生成一个jsvc的文件，将其复制到tomcat的bin目录
cp jsvc /usr/local/apache-tomcat-8.5.23/bin/

3. 建立一个用来运行Tomcat的用户

useradd tomcat -s /usr/sbin/nologin

4. 修改启动脚本文件

vim /usr/local/apache-tomcat-8.5.23/bin/daemon.sh

   找到如下内容
test ".$TOMCAT_USER" = . && TOMCAT_USER=tomcat
#Set JAVA_HOME to working JDK or JRE
#JAVA_HOME=/opt/jdk-1.6.0.22
    修改TOMCAT_USER=tomcat为你指定用来运行tomcat的用户名，去除JAVA_HOME前的注释（即“#”号），并设置为JDK的所在目录。

    在文件靠前位置的注释中加入下面的内容

#chkconfig: - 80 20

5. 修改相关目录和文件权限

chown -R tomcat.tomcat /usr/local/apache-tomcat-8.5.23
chmod a+x /usr/local/apache-tomcat-8.5.23/bin/daemon.sh

6.配置环境变量

tail -6 /etc/profile

unset -f pathmunge
export PATH=/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/pureftpd/bin:/usr/local/tomcat/bin
export JAVA_HOME=/usr/local/jdk1.8.0_60
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
export TOMCAT_HOME=/usr/local/tomcat

source /etc/profile

7.放置jenkins.war程序到站点目录

[email protected]_82_178_redhat tasks]# cd /usr/local/tomcat/webapps/
[[email protected]_82_178_redhat webapps]# ls
jenkins.war  ROOT

8.启动tomcat服务

启动前先检查tomcat配置文件 server.xml基本语法

[[email protected]_82_178_redhat bin]# which configtest.sh
/usr/local/tomcat/bin/configtest.sh

catalina.sh  configtest

查看tomcat和jdk的版本号

catalina.sh version
daemon.sh version
[[email protected]_82_178_redhat tomcat]# daemon.sh version

到此处tomcat启动成功

9.tomcat服务的控制台的日志

grep ‘Jenkins initialization thread‘ /usr/local/tomcat/logs/catalina-daemon.out

日志可以看到jenkins服务部署成功

同时在/home/tomcat/ 下面生成两个隐藏目录

[[email protected]_82_178_redhat tomcat]# ls -al /home/tomcat/
total 16
drwxr-xr-x  4 tomcat tomcat 4096 Apr 21 18:12 .
drwxr-xr-x. 3 root   root   4096 Apr 21 17:40 ..
drwxr-xr-x  9 tomcat tomcat 4096 Apr 21 18:13 .jenkins
drwx------  2 tomcat tomcat 4096 Apr 21 18:12 .oracle_jre_usage

.jenkins文件下存放着jenkins注册时的相关的重要的密码文件等

[[email protected]_82_178_redhat tomcat]# cat /home/tomcat/.jenkins/secrets/initialAdminPassword
e57476c34eca47869fbe5100900ade4a

10.注册jenkins服务

11.让tomcat服务开机自启动

ln -sv /usr/local/tomcat/bin/daemon.sh /etc/init.d/tomcat8

[[email protected]_82_178_redhat ~]#ln -sv /usr/local/tomcat/bin/daemon.sh /etc/init.d/tomcat8
‘/etc/init.d/tomcat8’ -> ‘/usr/local/tomcat/bin/daemon.sh’
[[email protected]_82_178_redhat ~]# ll /etc/init.d/tomcat8
lrwxrwxrwx 1 root root 31 Apr 21 19:19 /etc/init.d/tomcat8 -> /usr/local/tomcat/bin/daemon.sh
/etc/init.d/tomcat8 stop
/etc/init.d/tomcat8 start

[[email protected]_82_178_redhat ~]# chkconfig --add tomcat8
[[email protected]_82_178_redhat ~]# chkconfig tomcat8 on
[[email protected]_82_178_redhat ~]# chkconfig --ist|grep tomcat8
--ist: unknown option
[[email protected]_82_178_redhat ~]# chkconfig --list|grep tomcat8

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use ‘systemctl list-unit-files‘.
      To see services enabled on particular target use
      ‘systemctl list-dependencies [target]‘.

tomcat8         0:off   1:off   2:on    3:on    4:on    5:on    6:off
