java进程user是jenkins_部署jenkins,采用普通用户tomcat来启动tomcat服务

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

root@VM_82_178_redhat tasks]# cd /usr/local/tomcat/webapps/

[root@VM_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

[root@VM_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

[root@VM_82_178_redhat tomcat]# daemon.sh version

Still running according to PID file /usr/local/tomcat/logs/catalina-daemon.pid, PID is 21217

查看启动进程

[root@VM_82_178_redhat ~]# ps -ef|grep jsvc

查看服务端口

[root@VM_82_178_redhat ~]# netstat -lntup|grep jsvc

9.tomcat服务的控制台的日志

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

[root@VM_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 ..

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

[root@VM_82_178_redhat tomcat]# cat /home/tomcat/.jenkins/secrets/initialAdminPassword

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

[root@VM_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’

[root@VM_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

[root@VM_82_178_redhat ~]# chkconfig --add tomcat8

[root@VM_82_178_redhat ~]# chkconfig tomcat8 on

[root@VM_82_178_redhat ~]# chkconfig --ist|grep tomcat8

--ist: unknown option

[root@VM_82_178_redhat ~]# chkconfig --list|grep tomcat8
