# Jdk
|
||
1. 下载JDK：[华为镜像](https://repo.huaweicloud.com/java/jdk/8u202-b08/)
|
||
2. 上传到服务器
|
||
3. 复制到 /usr/jdk（没有新建）
|
||
|
||
```shell
|
||
$ cp jdk-8u211-linux-x64.tar.gz /usr/jdk
|
||
```
|
||
|
||
4. 修改配置文件
|
||
|
||
```linux
|
||
$ vim /etc/profile
|
||
```
|
||
|
||
5. 配置环境变量
|
||
|
||
```vim
|
||
export JAVA_HOME=/usr/jdk/jdk1.8.0_211
|
||
export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar
|
||
export PATH=$PATH:${JAVA_HOME}/bin
|
||
```
|
||
|
||
6. 刷新配置变量
|
||
|
||
```shell
|
||
$ source /etc/profile
|
||
```
|
||
|
||
# MySQL
|
||
1. centos上默认是没有yum源的，yum安装的是 MariaDB。所以我们需要自己先配置yum源。
|
||
- 访问：https://dev.mysql.com/downloads/repo/yum/
|
||
- 下载：Red Hat Enterprise Linux 7 / Oracle Linux 7 (Architecture Independent), RPM Package
|
||
2. 安装yum源
|
||
|
||
```shell
|
||
$ rpm -Uvh mysql80-community-release-el7-3.noarch.rpm
|
||
```
|
||
|
||
3. 查看有哪些版本的mysql，可以看到禁用和启用的版本，默认最新版本是开启的
|
||
|
||
```shell
|
||
$ yum repolist all | grep mysql
|
||
```
|
||
|
||
4. 修改安装版本
|
||
|
||
```shell
|
||
$ vim /etc/yum.repos.d/mysql-community.repo
|
||
```
|
||
|
||
|
||
|
||
|
||
6. 查看安装的mysql
|
||
|
||
```shell
|
||
$ rpm -qa | grep -i mysql
|
||
```
|
||
|
||
7. 默认使用安装
|
||
|
||
```shell
|
||
$ yum install -y mysql-community-server
|
||
```
|
||
|
||
8. 启动mysql
|
||
|
||
```shell
|
||
$ systemctl start mysqld
|
||
```
|
||
查看状态
|
||
|
||
```shell
|
||
$ systemctl status mysqld
|
||
```
|
||
|
||
9. 登录数据库，修改数据库密码
|
||
mysql5.7的新特性之一就是在初始化的时候会生成一个自定义的密码，然后你需要找到这个密码，登录的时候输入。注意，输入密码的时候是不显示。
|
||
|
||
```shell
|
||
grep 'temporary password' /var/log/mysqld.log
|
||
```
|
||
|
||
登录数据库：这里-p之后不用输入密码，回车后再输入。改过密码之后登录则是直接在-p后加密码了。
|
||
|
||
```shell
|
||
$ mysql -uroot -p
|
||
```
|
||
|
||
修改密码
|
||
*注意，修改的密码太简单会不给修改，把大小写字母和数字加上就肯定可以了。然后切记切记，mysql里面的命令要加分号！分号！分号！*
|
||
|
||
```
|
||
SET PASSWORD = PASSWORD('Admin123!');
|
||
```
|
||
|
||
10. 最后重启数据库，使配置生效。
|
||
|
||
11. 设置开机启动
|
||
```bash
|
||
$ systemctl enable mysqld
|
||
$ systemctl daemon-reload
|
||
```
|
||
|
||
# nginx
|
||
1. 添加依赖
|
||
|
||
```shell
|
||
$ apt-get install gcc
|
||
$ apt-get install libpcre3 libpcre3-dev
|
||
$ apt-get install zlib1g zlib1g-dev
|
||
# Ubuntu14.04的仓库中没有发现openssl-dev，由下面openssl和libssl-dev替代
|
||
# apt-get install openssl openssl-dev
|
||
$ sudo apt-get install openssl
|
||
$ sudo apt-get install libssl-dev
|
||
```
|
||
|
||
2. 下载nginx并且解压
|
||
|
||
3. 编译
|
||
|
||
```shell
|
||
# 进入nginx目录
|
||
$ /usr/local/nginx/nginx-1.13.7
|
||
# 执行命令
|
||
$ ./configure
|
||
# 执行make命令
|
||
$ make
|
||
# 执行make install命令
|
||
$ make install
|
||
```
|
||
|
||
4. 启动nginx
|
||
|
||
```shell
|
||
# 进入nginx启动目录
|
||
$ cd /usr/local/nginx/sbin
|
||
# 启动nginx
|
||
$ ./nginx
|
||
```
|
||
|
||
# zip、unzip
|
||
```shell
|
||
$ yum install -y zip unzip
|
||
``` |
