摘要:
- 本文是自己根据公司架构部署tomcat方法整理出来的文本
修改系统内核
修改linux的一些系统参数，以优化系统性能
- 修改LIMITS.CONF
$ vi /etc/security/limits.conf
# 增加
* soft nofile
* hard nofile
- 修改SYSCTL.CONF
# 备份
$ mv /etc/sysctl.conf /etc/sysctl.conf.bak $ vi /etc/sysctl.conf
# 插入

安装APR
- 下载apr-1.5.2.tar.gz和apr-util-1.5.4.tar.gz
安装apr，方便tomcat 开启aoi
apr下载地址
$ tar -zxvf apr-1.5..tar.gz
$ tar -zxvf apr-util-1.5..tar.gz
$ yum install gcc gcc-c++ autoconf libtool # apr安装
$ cd apr-1.5.
$ ./configure --prefix=/usr/local/apr
# --prefix=/usr/local/apr指apr的安装路径，以下要用到
$ make
$ make install # apr-util安装
$ cd apr-util-1.5.
$ ./configure --with-apr=/usr/local/apr
# --with-apr=/usr/local/apr 指定APR安装路径
$ make
$ make install
安装JDK1.7
下载jdk-7u76-linux-x64.tar.gz 拷贝到/usr/local下面
cd /usr/local
$ tar -zxvf jdk-7u76-linux-x64.tar.gz # mv 重命名 为jdk1..0_76
mv jdk1..0_76 jdk1. # 在环境变量/etc/profile里配置JAVA_HOME
JAVA_HOME=/usr/local/jdk1.
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME PATH CLASSPATH # 环境变量立即生效
$ source .bash_profile
编译安装tomcat
创建DATA目录
$ mkdir /data
复制TOMCAT到目标目录并解压
$ cp apache-tomcat-7.0..tar.gz /data
$ tar -zxvf apache-tomcat-7.0..tar.gz
# mv 重命名为你所需的项目名称，如zhnx
$ mv apache-tomcat-7.0. zhnx
进入TOMCAT精简目录
请参照下面步骤一步一步顺序操作
$ cd zhnx # 把项目除了bin lib conf目录的其它全部删除
$ rm -rf LICENSE logs NOTICE RELEASE-NOTES RUNNING.txt temp/webapps/work/ # 在同目录新建三个文件夹domain、server、sbin
$ mkdir domain
$ mkdir server
$ mkdir sbin # 把bin 和lib目录移动到server下面
$ mv bin/ server/
$ mv lib/ server/ # 把conf目录移动到domain下面
$ mv conf/ domain/ # 安装tomcat native 开启aio
# 进入server/bin目录下安装tomcat native 与apr连起来 开启tomcat aio模式
$ cd server/bin # 解压 tomcat native
$ tar -zxvf tomcat-native.tar.gz # 进入安装tomcat native目录
$ cd tomcat-native-1.1.-src
$ cd jni
$ cd native # 执行命令
$ ./configure --with-apr=/usr/local/apr --with-java-home=/usr/local/jdk1..0_76
$ make
$ make install # 创建项目目录(这里项目名称示例CENTER）
$ cd /data/zhnx/domain
$ mkdir center # 把conf目录移动到项目下
$ mv conf/ center/
拷贝并修改脚本启动参数
- 到目录/data/zhnx/sbin 下新建三个脚本，这里与center项目为例：startcenter.sh、stopcenter.sh和super.sh
$ cd /data/zhnx/sbin
# 脚本一
$ vi startcenter.sh
#!/bin/bash # 下面需要修改的地方
# 、HOME=/data/zhnx根据自己建的目录

# 下面需要修改的地方

# 脚本三
vi super.sh checkProcess(){

echo "ERROR:UNKNOWN COMMAND:\"$_command\" "
exit
}
- 到目录/etc/rc.d/init.d/下新建一个脚本，这里与center项目为例：center
$ cd /etc/rc.d/init.d/
# 脚本四
$ vi center #!/bin/sh # 下面需要修改的地方
# 、classname="tjtag=center" center服务名称
# 、_moduleName="center" modul名称
# 、start="/data/zhnx/sbin/startcenter.sh" 上面新建的脚本
# 、. /data/zhnx/sbin/super.sh 上面新建的脚本
classname="tjtag=center"
_command=$
_moduleName="center"
start="/data/zhnx/sbin/startcenter.sh"
. /data/zhnx/sbin/super.sh
case $_command in
start)
startProcess "Starting ${_moduldName}:"
;;
stop)
stopProcess "Stoping ${_moduldName}:"
;;
restart)
restartProcess "Stoping ${_moduldName}:" "Starting ${_moduldName}:"
;;
status)
getProcessStatus
;;
*)
commandError
;;
esac
删除原始的并替换修改过的SERVER.XML
$ cd /data/zhnx/domain/center/conf
$ rm -rf server.xml vi server.xml <?xml version='1.0' encoding='utf-8'?>

若有自己需要增加的jar就拷进去
$ cd /data/zhnx/server/lib 把jar考进去
项目部署
新建目录webapp名称与startcenter.sh里的webapps名称一样
日志名称与服务名一样
$ mkdir -p /data/zhnx/center_webapps
$ mkdir -p /data/zhnx/logs/center
center.war 部署至 center_webapps
部署时需将对应webapps目录下的文件及文件夹清空；
然后把项目war包拷入对应webapps目录下
启动服务
service center start
