Jenkins安装配置

Jenkins的安装配置备忘

master setup

1, install mysql

use mysql;
SET PASSWORD FOR 'root'@'%'=PASSWORD('Mysql123');
grant all privileges on *.* to root@"%" identified by "Mysql123";

mysqladmin -u root password oldpass "newpass"

2, install jdk and tomcat

vi ~/.bashrc

alias l="ls -l"

export JAVA_HOME=/var/java/jdk1.8.0_121
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

3, configure mysql

create database and tables

CREATE DATABASE IF NOT EXISTS jenkins DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

USE jenkins;

CREATE TABLE user_roles (
user_name VARCHAR(15) NOT NULL,
role_name VARCHAR(15) NOT NULL
) ENGINE=INNODB CHARSET=utf8 COLLATE=utf8_unicode_ci;

CREATE TABLE users (
user_name VARCHAR(15) NOT NULL,
user_pass VARCHAR(250) NOT NULL
) ENGINE=INNODB CHARSET=utf8 COLLATE=utf8_unicode_ci;

digest password and insert data

./digest.sh -a "SHA-512" -i 1000 -s 16 -k 256 -h "org.apache.catalina.realm.MessageDigestCredentialHandler" admin

insert into user_roles(user_name,role_name) values ("admin","admin");
insert into users(user_name,user_pass) values ("admin","b0ecf0b3b6e99c46b037e38f85c4f2ab2e73d9374b65ee81e517cff99ccb0e7e$1$b7640d2d66a16263f66eabed1f784c87");    

4, configure tomcat

put mysql driver to tomcat lib directory

➜ lib pwd
/data/apache-tomcat-8.5.15/lib
➜ lib ls -l mysql-connector-java-5.1.26-bin.jar 
-rwxr-xr-x. 1 jenkins jenkins 855948 7月 24 2013 mysql-connector-java-5.1.26-bin.jar

/data/apache-tomcat-8.5.15/conf/tomcat-users.xml

<role rolename="manager-gui"/>
<user username="admin" password="admin" roles="manager-gui"/>

/data/apache-tomcat-8.5.15/conf/context.xml

<Resources cachingAllowed="true" cacheMaxSize="100000" />

enable remote access for tomcat admin, webapps/manager/META-INF/context.xml

<Context antiResourceLocking="false" privileged="true" >
  <!--
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="192\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  -->
</Context>

update server.xml for mysql connection

<Realm className="org.apache.catalina.realm.LockOutRealm">
    <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
                resourceName="UserDatabase"/>
    <Realm className="org.apache.catalina.realm.JDBCRealm"
        driverName="org.gjt.mm.mysql.Driver"
        connectionURL="jdbc:mysql://localhost:3306/jenkins?autoReconnect=true&amp;user=root&amp;password=Mysql123"
        userTable="users" userNameCol="user_name" userCredCol="user_pass"
        userRoleTable="user_roles" roleNameCol="role_name">
        
        <!-- digest.bat -a "SHA-512" -i 1000 -s 16 -k 256 -h "org.apache.catalina.realm.MessageDigestCredentialHandler" admin -->
        <CredentialHandler className="org.apache.catalina.realm.MessageDigestCredentialHandler"
                algorithm="SHA-512"
                iterations="1000"
                keyLength="256"
                saltLength="16" />
    </Realm> 
</Realm>

setup jenkins authentication to delegate to servlet containler

5, user and ssh key setup

groupadd jenkins
useradd jenkins -g jenkins
sudo passwd jenkins
ssh-keygen -b 2048 -t rsa
ssh-copy-id -i .ssh/id_rsa.pub jenkins@10.0.0.5

chage -M 99999 jenkins
chage -l jenkins

6, jenkins install and initialization

access http://10.0.0.3:8081/jenkins/credentials/store/system/domain/_/ and click “Add Credentials”, choose “SSH Username with private key” and fill
username: jenkins
Private Key - Enter directly: that is jenkins master user(jenkins)’s ssh private key

slave setup

install jdk and maven

/etc/profile

export JAVA_HOME=/data/jdk1.8.0_91
export PATH=/usr/local/nginx/sbin:/usr/local/php/bin:/usr/local/apache/bin:/usr/local/mariadb/bin:$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

install fpm

通过gem安装fpm库时，可能会报错

gem install fpm

ERROR:  Loading command: install (LoadError)
    no such file to load -- zlib
ERROR:  While executing gem ... (NameError)
    uninitialized constant Gem::Commands::InstallCommand

解决办法是：

yum install zlib-devel
yum install openssl

进入ruby源码文件夹，安装ruby自身提供的zlib包

make clean
./configure --with-openssl-dir=/usr/local/openssl
cd ext/zlib
ruby ./extconf.rb
cd ..
make
make install

更改gem源为国内源

gem sources --add http://gems.ruby-china.org/ --remove https://rubygems.org/
gem sources -l

build package
