centos7安装JDK1.7+tomcat7+mysql5.5

 一、首先安装JDK1.7

步骤1、解压tar包在当前目录

[root@localhost usr]#tar -xzvf jdk-7u25-linux-x64.tar.gz

步骤2：配置环境变量

在etc/profile文件下添加

export JAVA_HOME=/usr/java/jdk1.7.0_25

export CLASSPATH=/usr/java/jdk1.7.0_25/lib

export PATH=$JAVA_HOME/bin:$PATH

添加环境变量后使用如下命令：

[root@localhost ~]# source /etc/profile使配置文件立即生效，在

验证环境变量是否生效

[root@localhost ~]# echo $JAVA_HOME

/usr/java/jdk1.7.0_25

[root@localhost ~]# echo $PATH

/usr/java/jdk1.7.0_25/bin:/usr/kerberos/sbin:/usr/kerberos/bin

:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin

[root@localhost ~]# echo echo $CLASSPATH

/usr/java/jdk1.7.0_25/lib

步骤3：使用java -version命令验证是否安装成功

[root@localhost tmp]# java -version

java version "1.7.0_25"

Java(TM) SE Runtime Environment (build 1.7.0_25-b15)

Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

能看到以上信息表示已经安装成功

二、安装tomcat7

其实tomcat不用安装的，直接下载tomcat的tar包，使用tar -xvzf tomcat7.xx.tar.gz解压后，直接把java项目war文件上传到tomcat的webapps目录下，然后进入tomcat目录下的bin目录使用启动tomcat的命令：./startup.sh 就这么简单。

三、安装mysql

1、首先安装 cmake

[root@localhost /]# yum install cmake

[root@localhost ~]#/usr/sbin/groupadd mysql

[root@localhost ~]#/usr/sbin/useradd -g mysql mysql

[root@localhost ~]# tar xvf mysql-5.5.16.tar.gz
[root@localhost ~]# cd mysql-5.5.16/

[root@localhost ~]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/var/mysql/data \
-DMYSQL_USER=mysql

如果在执行这一步时，报以下错误

-- MySQL 5.5.16
-- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake:83 (MESSAGE):
Curses library not found. Please install appropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.

解决方式：

[root@localhost mysql]# yum install ncurses-devel.x86_64
[root@localhost mysql]#make clean
[root@localhost mysql]#rm -rf CMakeCache.txt
[root@localhost mysql]# cmake . -LH

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
Alternatively you can run:
./bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd ./mysql-test ; perl mysql-test-run.pl
Please report any problems with the ./bin/mysqlbug script!
shell> cp support-files/my-medium.cnf /etc/my.cnf
shell> bin/mysqld_safe --user=mysql &
# Next command is optional
//查看MYSQL是否正常启动

[root@localhost ~]# chmod +w /usr/local/mysql
[root@localhost ~]# chown -R mysql:mysql /usr/local/mysql #改变目录拥有者与所属组

[root@localhost ~]# cp my-large.cnf /etc/my.cnf # 选择默认 配置文件 适合大型服务器
[root@localhost ~]# cp mysql.server /etc/init.d/mysqld # 复制启动文件

将 mysql 加入开机启动
[root@localhost ~]# chmod +x /etc/init.d/mysqld
[root@localhost ~]# vi /etc/init.d/mysqld （编辑此文件，查找并修改以下变量内容：）
basedir=/usr/local/mysql
datadir=/var/mysql/data

[root@localhost ~]# chkconfig --add mysqld
[root@localhost ~]# chkconfig --level 345 mysqld on

启动 mysql
[root@localhost ~]# service mysqld start

给mysql设置密码，mysql默认密码为空

通过登录mysql系统，
#mysql -uroot -p
Enter password: 【输入原来的密码】默认密码为空，直接按回车键
mysql>use mysql;
mysql>update user set password=passworD("test") where user='root';
mysql>flush privileges;
mysql>exit;

mysql安装好，默认没有打开远程访问，下面打开远程访问方法

通过登录mysql系统，
#mysql -uroot -p

Enter password: 输入密码成功登录后

mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;

mysql>flush privileges;
mysql>exit;

这就完事了，第一次写很乱，希望能帮助大家。
