Do you really know how to deploy Linux?

1. jdk installation

The first step is to upload the jdk1.6.0_45
app window to modify the permissions, cascade the lower-level directory files, and have executable permissions chmod 777 jdk1.6.0_45 The second step is to install jdk 
./jdk-6u45-linux-x64.bin The
third step to set the environment Variable
export JAVA_HOME=/app/jdk1.6.0_45
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar The
fourth step is to check whether the configuration is correct
[bgzdh@localhost app]$ java 
[bgzdh@localhost app]$ javac
[bgzdh@localhost app]$ java -version

1. memcached installation

1. Install the dependent library libevent
1. Check whether it has been installed, command: rpm -qa|grep libevent 
2. If it is installed and the version is lower than 2.0.21, uninstall it, command: rpm -e libevent-1.4.13-4.el6 .x86_64 --nodeps
3. Install libevent, upload the installation package to a directory other than /usr, command:
tar zxvf libevent-2.0.21-stable.tar.gz
cd libevent-2.0.21-stable
./configure --prefix= /usr/local/libevent
make
make install
Note: 
1) Root authority may be required to execute make install. 
2) Libevent will be installed under /usr/local
4. Test whether libevent is installed successfully: ls -al /usr/local|grep libevent So
far, libevent is installed; 2. Install memcache install tar zxvf memcached-1.4.2.tar.gz
cd memcached-memcached-1.4.2
./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent/
make
make install Note: 
1) Root authority may be required to execute make install. 
2) memcached will be installed under /usr/local and the
memcached installation is now complete; 3. Start the service memcache
cd /usr/local/memcached/bin ./memcached -m 100000 -d start -c 4096 ps -eaf|grep memcached display process Number four, verify that the telnet IP 11211 stats has information displayed on it.

1. Install weblogic

Step 5 Install weblogic [bgzdh@localhost app]$ java -jar wls1036_generic.jar  Step 6 Install domain cd Oracle/Middleware/wlserver_10.3/common/bin Step 7 Authorize bgzdh's user_projects directory under chmod 777 user_projects cd user_projects /domains/base_domain/bin chmod 777 startWebLogic.sh
./startWebLogic.sh Step 8: Test whether weblogic starts the console http://20.0.2.106:7001/console

Redhat Tomcat starts automatically after booting

 

环境说明：redhat6.3企业版；tomcat-6.0.44

#1#编辑startup.sh 在最上面添加如下三行，并保存

vi /app/apache-tomcat-6.0.44/bin/startup.sh

#chkconfig:2345 80 90

#description:tomcat auto start

#processname:tomca

#2#编辑catalina.sh，在export QIBM_MULTI_THREADED=Y下面添加如下三行并保存（注意tomcat 路径要写对）

vi /app/apache-tomcat-6.0.44/bin/catalina.sh

export CATALINA_BASE=/app/apache-tomcat-6.0.44

export CATALINA_HOME=/app/apache-tomcat-6.0.44

export CATALINA_TMPDIR=/app/apache-tomcat-6.0.44

#3#添加链接

ln -s /app/apache-tomcat-6.0.44/bin/startup.sh /etc/rc.d/init.d/tomcat6

#4#检查并给执行授权

cd /etc/rc.d/init.d 

ll

chmod +x tomcat6

chmod 777 tomcat6

#5#添加开机启动服务

chkconfig --add tomcat6

#6#检查开机启动服务是否存在

chkconfig --list

1. Linux 环境变量配置

环境说明：redhat 6.3企业版

#1#打开编辑profile并保存。

vi /etc/profile

JAVA_HOME=/usr/lib/jvm/jdk6

PATH=$PATH:$JAVA_HOME/bin

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export JAVA_HOME

export PATH

ecport CLASSPATH

1. Tomcat 优化配置

#1# 打开tomcat_home/conf/server.xml，编辑保存

maxThreads="250" maxHttpHeaderSize="8192"

emptySessionPath="true" protocol="HTTP/1.1" maxThreads="1000" minSpareThreads="50" maxSpareThreads="100" acceptCount="500" />

其中：
• maxThreads：tomcat可用于请求处理的最大线程数，默认是200
• minSpareThreads：tomcat初始线程数，即最小空闲线程数
• maxSpareThreads：tomcat最大空闲线程数，超过的会被关闭
• acceptCount：当所有可以使用的处理请求的线程数都被使用时，可以放到处理队列中的请求数，超过这个数的请求将不予处理.默认100

#2# 打开tomcat_home/bin/catalina.sh，这个下边cygwin=false添加如下；（注意内存按照实际机器内存的四分之一到四分之二配置。）

JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8

-server -Xms1024m -Xmx2048m

-XX:NewSize=512m -XX:MaxNewSize=512m -XX:PermSize=512m

-XX:MaxPermSize=1024m -XX:+DisableExplicitGC"

1. Linux 系统挂载数据盘

适用系统：Linux（Redhat , CentOS，Debian，Ubuntu）

*  Linux的云服务器数据盘未做分区和格式化，可以根据以下步骤进行分区以及格式化操作。 下面的操作将会把数据盘划分为一个分区来使用。 1、查看数据盘 在没有分区和格式化数据盘之前，使用 “df –h”命令，是无法看到数据盘的，可以使用“fdisk -l”命令查看。 如下图： 友情提示： 若您执行fdisk -l命令，发现没有 /dev/xvdb 表明您的云服务无数据盘，那么您无需进行挂载，此时该教程对您不适用 2、 对数据盘进行分区 执行“fdisk -S 56 /dev/xvdb”命令，对数据盘进行分区； 根据提示，依次输入“n”，“p”“1”，两次回车，“wq”，分区就开始了，很快就会完成。 3、 查看新的分区 使用“fdisk -l”命令可以看到，新的分区xvdb1已经建立完成了。  4、格式化新分区 以ext3为例： 使用“mkfs.ext3 /dev/xvdb1”命令对新分区进行格式化，格式化的时间根据硬盘大小有所不同。 (也可自主决定选用其它文件格式，如ext4等)  5、添加分区信息 使用“echo '/dev/xvdb1  /mnt ext3    defaults    0  0' >> /etc/fstab”（不含引号）命令写入新分区信息。
然后使用“cat /etc/fstab”命令查看，出现以下信息就表示写入成功。 注： ubuntu12.04 does not support barriers, so the correct way to write it is: echo'/dev/xvdb1 /mnt ext3 barrier=0 0 0'>> /etc/fstab * If you need to mount the data disk separately to a folder, such as separate Used to store web pages, you can modify the /mnt part of the above command. 6. Mount the new partition. Use the "mount -a" command to mount the new partition, and then use the "df -h" command to view. The following message indicates that the mount is successful , You can start using the new partition.
