# 一、搭建JavaEE环境 #

## 安装JDK ##

安装步骤  
0) 先将软件通过xftp5 上传到 /opt 下

1) 解压缩到 /opt

2) 配置环境变量的配置文件vim /etc/profile

![20190806161311980.png][]

![20190806161706351.png][]

JAVA\_HOME=/opt/jdk1.7.0\_79  
 PATH=/opt/jdk1.7.0\_79/bin:$PATH  
 export JAVA\_HOME PATH

3）注销用户，环境变量才能生效

运行级别3：使用命令logout

运行级别5：

# 三、eclipse安装  #

Eclipse的安装  
步骤 :  
1) 解压缩到/opt

![20190806172033654.png][]  
2) 启动eclipse，配置jre和server

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3OTA5NTA4_size_16_color_FFFFFF_t_70 9][]

#  四、MySQL的安装 #

## 清除MySQL ##

注意: 先删除一下Mysql 相关的软件..  
![2019080617304390.png][]

![20190806173301407.png][]

##  安装MySQL ##

安装gcc环境

yum \-y install make gcc-c++ cmake bison-devel  ncurses-devel

![20190806173408699.png][]

解压MySQL

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3OTA5NTA4_size_16_color_FFFFFF_t_70 10][]

编译：

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci

![201908061739234.png][]

编译并安装（先执行make在执行make install，也可以分开写）

make && make install

![2019080617404992.png][]

整个过程需要30分钟左右……漫长的等待

### 配置MySQL  ###

使用下面的命令查看是否有mysql用户及用户组

cat /etc/passwd 查看用户列表

cat /etc/group  查看用户组列表

如果没有就创建

groupadd mysql

useradd \-g mysql mysql

![20190806174310451.png][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3OTA5NTA4_size_16_color_FFFFFF_t_70 11][]

修改/usr/local/mysql权限

chown \-R mysql:mysql /usr/local/mysql

![20190806174525574.png][]

初始化配置，进入安装路径（在执行下面的指令），执行初始化配置脚本，创建系统自带的数据库和表

cd /usr/local/mysql

![20190806174554772.png][]

scripts/mysql\_install\_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql    \[这是一条指令\]

![20190806174644772.png][]

注：在启动MySQL服务时，会按照一定次序搜索my.cnf，先在/etc目录下找，找不到则会搜索"$basedir/my.cnf"，在本例中就是 /usr/local/mysql/my.cnf，这是新版MySQL的配置文件的默认位置！

注意：在CentOS 6.8版操作系统的最小安装完成后，在/etc目录下会存在一个my.cnf，需要将此文件更名为其他的名字，如：/etc/my.cnf.bak，否则，该文件会干扰源码安装的MySQL的正确配置，造成无法启动。

修改名称，防止干扰：

mv /etc/my.cnf /etc/my.cnf.bak

启动MySQL

添加服务，拷贝服务脚本到init.d目录，并设置开机启动

\[注意在 /usr/local/mysql 下执行\]

cp support\-files/mysql.server /etc/init.d/mysql

![20190806174932289.png][]

chkconfig mysql on

![20190806174958923.png][]

service mysql start  \--启动MySQL

![2019080617501696.png][]

查看端口3306是否启动

![20190806175106677.png][]

执行下面的命令修改root密码

cd /usr/local/mysql/bin

./mysql \-uroot

mysql> SET PASSWORD = PASSWORD('root');
