单点登陆_搭建linux开发环境

1. 使用工具将 linux版本jdk与tomcat上传至服务器,并使用tar –zxvf 命令将其解压宿

2. 配置jdk与tomcat环境变量

修改 用户目录下的 .bash_profile文件 例如:/home/zhangsan/.bash_profileexport JAVA_HOME=/home/javadev/jdk1.7.0_05export CATALINA_HOME=/home/javadev/apache-tomcat-7.0.29export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$CATALINE-HOME/bin:$PATHexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar在执行./startup.sh,或者./shutdown.sh的时候，爆出了Permission denied，其实很简单，就是今天在执行tomcat的时候，用户没有权限，而导致无法执行，用命令chmod 修改一下bin目录下的.sh权限就可以了如chmod u+x *.sh

3. 测试方问jdk 与tomcat

编写Hello.java javac Hello.java java Hello

进入tomcat bin目录 使用./startup.sh命令启动

**假如SuSE linux 防火墙开了,别的机器是无法访问的,需要了解一下相关知识: 例子 : 我的需求是允许所有地址访问80端口，只允许指定的地址访问22端口
所以我就在FW_SERVICES_EXT_TCP里面写了80，在FW_SERVICES_ACCEPT_EXT里面写了xxxxx（指定地址），tcp，22
结果发现只有80可以访问，22无法访问！！！
纠结了半天发现原文说的FW_SERVICES_EXT_TCP配置会覆盖FW_SERVICES_ACCEPT_EXT配置指的是2种配置方法无法共存的意思。也就是说你只能选择一种方法，而不能一个端口用第一种方法，另一个端口用第二种方法！！

开启防火墙命令rcSuSEfirewall2 start 防火墙帮助命令中可已看到其他命令rcSuSEfirewall2 –h
防火墙开放端口 i. 进入 /etc/sysconfig/ 目录，用 vi 命令编辑 SuSEfirewall2 文件，
-># vi SuSEfirewall2 在文件中找到FW_SERVICES_EXT_TCP，在其后面加上服务名或者是服务对应的端口，如SSH,
FW_SERVICES_EXT_TCP=”ssh” 或 FW_SERVICES_EXT_TCP=”22″ 保存之后退出。

ii. 重启防火墙，以使配置生效，
-># rcSuSEfirewall2 restart

4.接下来搭建数据库环境(mysql)

4.1 检查mysql rpm相关的包是否安装

rpm -qa | grep -i mysqlmysql-libs-5.1.61-4.el6.x86_64如果存在删除：rpm -e mysql-libs-5.1.61-4.el6.x86_64error: Failed dependencies:        libmysqlclient.so.16()(64bit) is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64        libmysqlclient.so.16(libmysqlclient_16)(64bit) is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64        mysql-libs is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64忽略依赖包删除    [root@redis1 ~]# rpm -e --nodeps mysql-libs-5.1.61-4.el6.x86_64或者删除依赖包 yum -y remove mysql-libsrpm -qa | grep -i mysql

4.2 上传下载的安装包MySQL-5.6.28-1.el6.x86_64.rpm-bundle.tar

解压： tar -xvf MySQL-5.6.28-1.el6.x86_64.rpm-bundle.tar

4.3 安装mysql服务端：

rpm -ivh MySQL-server-5.6.28-1.el6.x86_64.rpmwarning: MySQL-server-5.6.28-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYerror: Failed dependencies:        libnuma.so.1()(64bit) is needed by MySQL-server-5.6.28-1.el6.x86_64        libnuma.so.1(libnuma_1.1)(64bit) is needed by MySQL-server-5.6.28-1.el6.x86_64        libnuma.so.1(libnuma_1.2)(64bit) is needed by MySQL-server-5.6.28-1.el6.x86_64缺失依赖包yum install numactlrpm -ivh MySQL-server-5.6.28-1.el6.x86_64.rpmwarning: MySQL-server-5.6.28-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYPreparing...                ########################################### [100%]   1:MySQL-server           ########################################### [100%]warning: user mysql does not exist - using rootwarning: group mysql does not exist - using root

4.4 安装mysql 客户端

rpm -ivh MySQL-client-5.6.28-1.el6.x86_64.rpm warning: MySQL-client-5.6.28-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYPreparing...                ########################################### [100%]   1:MySQL-client           ########################################### [100%]

4.5 修改mysql配置文件

vi /etc/my.cnf[mysqld]Options for mysqld process:skip-grant-tablescharacter_set_server=utf8lower_case_table_names=1max_connections=1000datadir=/var/lib/mysql[root@mysqlmaster mysql]# service mysql startStarting MySQL SUCCESS! **4.6 登录修改root密码**查看root 用户的密码cat /root/.mysql_secretThe random password set for the root user at Fri Dec 18 14:12:44 2015 (local time): g478da9wvEZniGqaroot用户登录mysql -uroot -pEnter password: Welcome to the MySQL monitor.

4.7 设置root用户支持远程登录：

mysql> select host,user,password from user;
+————-+——+——————————————-+ | host | user | password |
+————-+——+——————————————-+ | localhost | root | *F4368ED34678C82DC260E668501F2FA7201F34EB | |

5.启动tomcat报错
