安装实操：JDK+NGINX+TOMCAT

安装实操：JDK+NGINX+TOMCAT

1 添加依赖的系统工具：
yum -y install gcc gcc-c++ autoconf automake
或执行比较全的命令（如果执行make && make install 命令无法找到的情况）
yum -y install ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison autoconf automake glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel libtool* zlib-devel libxml2-devel libjpeg-devel libpng-devel libtiff-devel fontconfig-devel freetype-devel libXpm-devel gettext-devel curl curl-devel pam-devel e2fsprogs-devel krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers

2 安装JDK
上传 jdk-6u37-linux-x64-rpm.bin 到 /usr/java目录下，因为初始化时没有java目录，自行创建即可。
cd /usr/java
执行权限并执行
# chmod u+x jdk-6u37-linux-x64-rpm.bin
# ./jdk-6u37-linux-x64-rpm.bin

Java(TM) SE Development Kit 6 successfully installed.

Product Registration is FREE and includes many benefits:
* Notification of new versions, patches, and updates
* Special offers on Oracle products, services and training
* Access to early releases and documentation

Product and system data will be collected. If your configuration
supports a browser, the JDK Product Registration form will
be presented. If you do not register, none of this information
will be saved. You may also register your JDK later by
opening the register.html file (located in the JDK installation
directory) in a browser.

For more information on what data Registration collects and
how it is managed and used, see:
http://java.sun.com/javase/registration/JDKRegistrationPrivacy.html

Done.
安装完成，配置环境变量
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

#PATH=$PATH:$HOME/bin

#export PAT

JAVA_HOME=/usr/java/jdk1.6.0_37
CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar

PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:/sbin

export PATH JAVA_HOME CLASSPATH
unset USERNAME

第二种情况配置环境变：可能 .bash_profile 不起作用，则要去/etc/ 去配置环境变量
vi /etc/profile
在文件最后加上
JAVA_HOME=/usr/java/jdk1.6.0_37
CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar

PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:/sbin

export PATH JAVA_HOME CLASSPATH

3 安装NGINX
3.1 安装相关依赖
yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel
NGINX 要用到pcre 和openssl
3.2 上传并解压包去/usr/src/ 目录编译
#  tar zxvf nginx-1.2.6.tar.gz -C /usr/src/
cd /usr/src/ nginx-1.2.6/
执行：
# ./configure
# make && make install
nginx默认安装到/usr/local/nginx目录下，同通过./configure --help命令查看nginx可选择的编译选项。

安装成功后
去/usr/local/nginx/sbin 启动
#./nginx
查看 ps –ef | grep nginx
[root@localhost sbin]# ps -ef | grep nginx
root     63423     1  0 10:22 ?        00:00:00 nginx: master process ./nginx
nobody   63424 63423  0 10:22 ?        00:00:00 nginx: worker process
root     63427 60747  0 10:22 pts/1    00:00:00 grep nginx
登录 http://localhost/ 查看
出现
Welcome to nginx!
If you see this page, the nginx web server is successfully installed and working. Further configuration is required.
For online documentation and support please refer to nginx.org.
Commercial support is available at nginx.com.
Thank you for using nginx.
表示成功。
4 安装tomcat
4.1 上传并解压到
# tar zxvf apache-tomcat-6.0.36.tar.gz -C /usr/local/
cd /usr/local
cp -r apache-tomcat-6.0.36/ tomcat
rm –rf apache-tomcat-6.0.36
这样就只剩下 tomcat目录了 /usr/local/tomcat

5 设置nginx 参数配置

6 安装mysql
centos 安装 mysql-server

直接yum install mysql-server

然后启动 /etc/rc.d/ini.d/mysqld start 启动一下就OK了

修改密码：
不用进入mysql执行
# mysqladmin -u root password lijian
lijian为新密码。

重启 mysql 命令:
/etc/init.d/mysqld restart

如果连接mysql 出现 host ... is not allowed to connect to this MySql server
说明权限有问题，执行以下授权即可。
进入mysql 执行：mysql –uroot –p
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'lijian' WITH GRANT OPTION;

6 部署应用
上传ROOT.war包到tomcat 的webapps下。

重启tomcat

完成相应的软连接。
命令最常用的参数是-s,具体用法是：ln -s 源文件 目标文件。
如：
ln -s /usr/local/pic/images/ /usr/local/tomcat/webapps/ROOT/images
ln -s /usr/local/pic/u/ /usr/local/tomcat/webapps/ROOT/u
ln -s /usr/local/pic/cloth/ /usr/local/tomcat/webapps/ROOT/cloth
ln -s /usr/local/pic/html/ /usr/local/tomcat/webapps/ROOT/html

ln -s /usr/local/pic/images/ /usr/local/nginx/html/images
ln -s /usr/local/pic/u/ /usr/local/nginx/html/u
ln -s /usr/local/pic/cloth/ /usr/local/nginx/html/cloth
ln -s /usr/local/pic/html/ /usr/local/nginx/html/html

注：
软连接创建命令： ln -s 目标文件(夹) link文件

tomcat配置：

修改context.xml，在context节点添加allowLinking="true"属性，如下

<Context allowLinking="true">
