CentOS 6.4安装jdk+tomcat+mysql+nginx

安装配置JDK

1、下载安装

上官网下载新版本的JDK，如jdk-7u45-linux-i586.tar.gz压缩包，放到Linux下任意目录，cd到该目录，执行以下命令：

mkdir –p /dev-tools/java
tar zxvfjdk-7u45-linux-i586.tar.gz -C /dev-tools/java

解压成功过后，jdk便位于/dev-tools/java下的jdk1.7.0_45目录了，如图



2、配置环境

从第一步，我们知道了jdk的解压目录就位于/dev-tools/java/jdk1.7.0_45，接着配置环境变量，通过修改.bashrc文件实现，执行以下命令：

Vi .bashrc

在文件末尾加上

export JAVA_HOME=/dev-tools/java/jdk1.7.0_45
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
exportPATH=${JAVA_HOME}/bin:$PATH

保存后退出。

执行

source~/.bashrc

修改马上生效

执行java –version能看到版本呢信息，JDK就安装配置成功了，如图





安装配置Tomcat

1、下载解压

跟JDK一样上官网http://tomcat.apache.org/download-70.cgi下载tomcat压缩包，如apache-tomcat-7.0.47.tar.gz，下载后放入任意目录cd到改目录执行以下命令解压：

mkdir –p /dev-tools/tomcat
tar zxvfapache-tomcat-7.0.47.tar.gz -C /dev-tools/tomcat

解压成功过后如图：



2、配置环境

1）打开端口

解压成功过后如果Linux有设置防火墙，就必须先在防火墙打开指定端口，tomcat默认http端口为8080，一下为打开8080端口的例子:

修改/etc/sysconfig/iptables文件，执行以下命令

vi /etc/sysconfig/iptables

增加一行

-A RH-Firewall-1-INPUT -m state--state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

如图，我把80端口也顺便打开了，以后要用到



保存退出，重启防火墙，执行命令

service iptablesrestart

2）设置开机启动

通过以上的设置，tomcat其实已经可以启动并正常访问了，只要执行

/dev-tools/tomcat/apache-tomcat-7.0.47/bin/startup.sh

就可以启动tomcat了（JDK已经正确安装）如图：





但是你每次启动都要输入一次未免太麻烦了，所以我们要设置开机自动启动tomcat。

a)把下面的代码保存为tomcat（蓝色字体为需要修改部分）文件，并让它成为可执行文件

chmod 755 tomcat

#!/bin/bash
#
# kenny kenny.zhou@tom.com
# /etc/rc.d/init.d/tomcat
# init script for tomcat precesses
#
# processname: tomcat
# description: tomcat is a j2se server
# chkconfig: 2345 86 16
# description:  Start up the Tomcat servlet engine.

if [ -f /etc/init.d/functions ]; then
. /etc/init.d/functions
elif [ -f /etc/rc.d/init.d/functions ]; then
. /etc/rc.d/init.d/functions
else
echo -e "/atomcat: unable to locate functions lib. Cannot continue."
exit -1
fi

RETVAL=$?

JAVA_HOME=/dev-tools/java/jdk1.7.0_45
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH
CATALINA_HOME="/dev-tools/tomcat/apache-tomcat-7.0.47"

case "$1" in
start)
if [ -f $CATALINA_HOME/bin/startup.sh ];
then
echo $"Starting Tomcat"
$CATALINA_HOME/bin/startup.sh
fi
;;
stop)
if [ -f $CATALINA_HOME/bin/shutdown.sh ];
then
echo $"Stopping Tomcat"
$CATALINA_HOME/bin/shutdown.sh
fi
;;
*)
echo $"Usage: $0 {start|stop}"
exit 1
;;
esac

exit $RETVAL

b)将tomcat文件拷贝到/etc/init.d/下，并运行：

chkconfig --add tomcat

重启，tomcat就能自动启动了。

PS：

启动tomcat：

service tomcat start

停止tomcat:

service tomcat stop　

安装配置nginx

1、编译安装nginx

a) 建立安装文件夹

mkdir -p /dev-tools/nginx
mkdir –p /dev-tools/pcre
cd /dev-tools

b) 安装依赖

yum install wget
yum install pcre
yum install openssl*
yum -y install gcc gcc-c++autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devellibxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-develkrb5 krb5-devel libidn libidn-devel openssl openssl-devel openldapopenldap-devel nss_ldap openldap-clients openldap-servers make
yum -y install gd gd2 gd-develgd2-devel

c) 建立用户

/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
ulimit -SHn 65535

d) 编译安装pcre(蓝色部分为安装路径)

wgetftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.32.tar.gztar zxvf pcre-8.32.tar.gzcd pcre-8.32./configure --prefix=/dev-tools/pcremake && make installcd ../

e) 编译安装nginx((蓝色部分为安装路径))

wget http://nginx.org/download/nginx-1.5.2.tar.gztar zxvf nginx-1.5.2.tar.gzcd nginx-1.5.2./configure --user=www --group=www --prefix=/dev-tools/nginx --with-http_stub_status_module --with-http_ssl_module--with-pcre=/dev-tools/pcre-8.32--with-http_realip_module
--with-http_image_filter_modulemakemake installcd ../

一切顺利了，安装结束后，执行

/dev-tools/nginx/sbin/nginx

启动nginx，默认监听80端口，如何打开80端口，看tomcat配置，如图





2、配置nginx与tomcat协作

修改nginx的配置文件

vi /dev-tools/nginx/conf/nginx.conf

如下

#user  nobody;
worker_processes  1;

#error_log logs/error.log;
#error_log  logs/error.log  notice;
#error_log logs/error.log  info;

#pid       logs/nginx.pid;

events {
worker_connections  1024;
}

http {
include       mime.types;
default_type  application/octet-stream;

#log_format  main '$remote_addr - $remote_user [$time_local] "$request" '
#                  '$status $body_bytes_sent"$http_referer" '
#                  '"$http_user_agent""$http_x_forwarded_for"';

#access_log  logs/access.log  main;

sendfile        on;
#tcp_nopush     on;

#keepalive_timeout  0;
keepalive_timeout  65;

#gzip  on;

server {
listen       80;
server_name  localhost;

#charset koi8-r;

#access_log  logs/host.access.log  main;

location / {
root  /dev-tools/tomcat/apache-tomcat-7.0.47/webapps/ROOT;
index  index.jsp index.html index.htm;
}

#error_page  404              /404.html;

# redirect servererror pages to the static page /50x.html
#
error_page   500 502 503 504  /50x.html;
location =/50x.html {
root   html;
}

# 代理tomcat
location ~ \.jsp${
root          /dev-tools/tomcat/apache-tomcat-7.0.47/webapps/ROOT;
proxy_pass http://127.0.0.1:8080;   #转向tomcat处理
}

}

}

保存配置，重新载入配置

/dev-tools/nginx/sbin/nginx -s reload

直接访问80端口下的index.jsp，如图：



Nginx已经可以成功将请求交给tomcat了。

3、开机自动启动nginx

vi /etc/rc.d/init.d/nginx

键入以下文本(蓝色字体按照实际修改)

#!/bin/bash

# chkconfig: - 85 15

# description: Nginx is a high-performance web and proxy server.

# It has alot of features, but it's not for everyone.

nginxd=/dev-tools/nginx/sbin/nginx

nginx_config=/dev-tools/nginx/conf/nginx.conf

nginx_pid=/var/run/nginx.pid

RETVAL=0

prog="nginx"

# Source function library.

. /etc/rc.d/init.d/functions

# Source networking configuration.

. /etc/sysconfig/network

# Check that networking is up.

[ ${NETWORKING} = "no" ] && exit 0

[ -x $nginxd ] || exit 0

# Start nginx daemons functions.

start() {

if [ -e $nginx_pid ];then

echo "nginxalready running...."

exit 1

fi

echo -n $"Starting$prog: "

daemon $nginxd -c${nginx_config}

RETVAL=$?

echo

[ $RETVAL = 0 ]&& touch /var/lock/subsys/nginx

return $RETVAL

}

# Stop nginx daemons functions.

stop() {

echo -n$"Stopping $prog: "

killproc $nginxd

RETVAL=$?

echo

[ $RETVAL = 0 ]&& rm -f /var/lock/subsys/nginx /var/run/nginx.pid

}

# reload nginx service functions.

reload() {

echo -n $"Reloading$prog: "

#kill -HUP `cat${nginx_pid}`

killproc $nginxd -HUP

RETVAL=$?

echo

}

# See how we were called.

case "$1" in

start)

start

;;

stop)

stop

;;

reload)

reload

;;

restart)

stop

start

;;

status)

status $prog

RETVAL=$?

;;

*)

echo $"Usage:$prog {start|stop|restart|reload|status|help}"

exit 1

esac

exit $RETVAL

保存后执行一下命令

修改权限

chmod 777 /etc/rc.d/init.d/nginx

添加开机启动

chkconfig --add nginx

chkconfig --level 2345 nginx on

PS：

启动mysql： service nginx start

停止mysql: service nginx stop

安装配置MySQL

1、下载安装MySql

执行命令

cd /dev-tools/

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.14-linux-glibc2.5-i686.tar.gz
tar zxvf mysql-5.6.14-linux-glibc2.5-i686.tar.gz

mv mysql-5.6.14-linux-glibc2.5-i686/ mysql

创建mysql账户与组

/usr/sbin/groupadd mysql

/usr/sbin/useradd -g mysql mysql

建立数据库文件存放的目录，安装数据库，并安装数据库文件到新建的目录

mkdir -p /home/data/mysql/data

/dev-tools/mysql/scripts/mysql_install_db --basedir=/dev-tools/mysql --datadir=/home/data/mysql/data --user=mysql

把启动脚本中的所有“/usr/local/mysql”路径替换为我们安装目录路径“/dev-tools/mysql”

sed -i"s#/usr/local/mysql#/dev-tools/mysql#g"/dev-tools/mysql/bin/mysqld_safe

2、配置MySql

a) 修改/etc/my.cnf如下（蓝色字体为需要修改或者需要添加的）

[mysqld]

datadir=/home/data/mysql/data

socket=/tmp/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assortedsecurity risks

symbolic-links=0

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

basedir=/dev-tools/mysql

datadir=/home/data/mysql/data

b) 建立服务，开机自动启动

vi /etc/init.d/mysqld

键入以下文本(蓝色字体按照实际路径填写)

#!/bin/sh

# chkconfig: - 85 15

# description: mysql

mysql_username="root"

mysql_password=""

function_start_mysql()

{

printf "StartingMySQL...\n"

/bin/sh /dev-tools/mysql/bin/mysqld_safe 2>&1 >/dev/null &

}

function_stop_mysql()

{

printf "StopingMySQL...\n"

/dev-tools/mysql/bin/mysqladmin -u${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown

}

function_restart_mysql()

{

printf"Restarting MySQL...\n"

function_stop_mysql

sleep 5

function_start_mysql

}

if [ "$1" = "start" ]; then

function_start_mysql

elif [ "$1" = "stop" ]; then

function_stop_mysql

elif [ "$1" = "restart" ]; then

function_restart_mysql

else

printf "Usage:/home/data/mysql/data{start|stop|restart|kill}\n"

fi

设置权限

chmod 777 /etc/init.d/mysqld

添加服务并让他开机自动启动

chkconfig --add mysqld

chkconfig --level 2345 mysqld on

PS：

启动mysql： service mysqld start

停止mysql: service mysqld stop
