Solo 开发环境搭建详细说明(用 MySQL8 数据库,对 Solo 开发指南的环境搭建的补充)

1. 环境搭建综述

讲述的是 CentOS7 的系统下安装 JDK,下载配置 Maven,安装 MySQL,配置 MySQL(改密码,建库),git clone solo 项目源码,编译启动的整个过程。

2. 安装 JDK12

2.1 安装之前先 rpm -qa |grep java检查一下系统有没有低版本的 java

[root@localhost ~]# rpm -qa |grep java
javapackages-tools-3.4.1-11.el7.noarch
java-1.8.0-openjdk-devel-1.8.0.212.b04-0.el7_6.x86_64
python-javapackages-3.4.1-11.el7.noarch
tzdata-java-2019a-1.el7.noarch
java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64
java-1.8.0-openjdk-headless-1.8.0.212.b04-0.el7_6.x86_64

2.2 用yum -y remove java*方法卸载低版本的 java

[root@localhost ~]# yum -y remove java*

再查看一下:(没有输出说明全部删除了)

[root@localhost ~]# rpm -qa |grep java
[root@localhost ~]# 

2.3 清理完旧的 Java 环境就可以开始安装新版本的 JDK 了。

2.3.1 先用命令搜索一下服务器镜像上的 JDK 版本

注:这里搜到的都是 openjdk,要装 oracle 的 JDK 需自行去官网下载

[root@localhost ~]# yum search jdk

完毕!

2.3.3 装完后查看一下 JDK 版本:(也是验证 java 和 javac 命令)

[root@localhost ~]# java -version
openjdk version "12.0.1" 2019-04-16
OpenJDK Runtime Environment 19.3 (build 12.0.1+12)
OpenJDK 64-Bit Server VM 19.3 (build 12.0.1+12, mixed mode, sharing)
[root@localhost ~]# javac -version
javac 12.0.1

3. 安装 Maven

3.1 先检查本机是否已经安装了 maven

[root@localhost ~]# mvn -v
-bash: mvn: 未找到命令

上面显示未找到命令表示没有安装 maven。

3.2 去 Maven 官网下载二进制文件。

3.2.1 我们先访问 apache-maven 网站的下载界面

maven1.png
maven.png
右键点击apache-maven-3.6.1-bin.tar.gz复制链接地址http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz

3.2.2 用 wget 下载apache-maven-3.6.1-bin.tar.gz到本地:

[root@localhost ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz


--2019-06-23 20:45:21--  http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz

100%[===================================================================>] 9,136,463   3.32MB/s 用时 2.6s   

2019-06-23 20:45:23 (3.32 MB/s) - 已保存 “apache-maven-3.6.1-bin.tar.gz” [9136463/9136463])

3.3 解压缩apache-maven-3.6.1-bin.tar.gz文件:

[root@localhost ~]# tar -zxf apache-maven-3.6.1-bin.tar.gz 
[root@localhost ~]# 

3.4 设置 maven 的路径

编辑.bash_profile文件(vi .bash_profile), 添加 maven 路径:$HOME/apache-maven-3.6.1/bin到 PATH 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:$HOME/apache-maven-3.6.1/bin

export PATH

3.5 切换一下用户,使 PATH 生效

当前用户是 root, 用su -命令重新切换到 root 用户,可使 PATH 生效

[root@localhost ~]# su -
上一次登录:日 623 21:02:56 CST 2019pts/0

3.6 查看 mvn 版本(顺便测试一下 mvn 是否可用)

[root@localhost ~]# mvn -v
Apache Maven 3.6.1 (d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555; 2019-04-05T03:00:29+08:00)
Maven home: /root/apache-maven-3.6.1
Java version: 12.0.1, vendor: N/A, runtime: /usr/lib/jvm/java-12-openjdk-12.0.1.12-1.rolling.el7.x86_64
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-957.21.2.el7.x86_64", arch: "amd64", family: "unix"

mvn 安装成功。

4. 安装 MySQL

假设本机之前没有安装 MySQL 或者低版本的 MySQL 已经清理了。具体操作步骤请参见第 2 章节中对 Java 低版本的清理步骤。

4.1 centos7 上安装并启动 MySQL8 的命令步骤

5. 配置 MySQL8

配置 MySQL8 包括修改 root 密码和建库。

5.1 获取 root@localhost 的初始密码

MySQL8 在安装后会创建一个 root@locahost 账户 ( 与之前版本不同,MySQL8 为远程连接root@%和本地连接root@locahost提供了不同的密码验证方式 )。MySQL8 将本地连接的初始密码放到了 /var/log/mysqld.log 文件中;我们可以用cat /var/log/mysqld.log | grep password命令查看初始密码。

[root@VM_0_11_centos solo]# cat /var/log/mysqld.log | grep password


2019-06-23T03:35:57.941668Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: n=Ti,P4?J(uE

注:上面n=Ti,P4?J(uE就是初始密码。

5.2 使用初始密码登录 mysql

[root@VM_0_11_centos solo]# mysql -uroot -p


Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 12

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

5.3 修改 root 密码

MySQL8 的 root 用户的验证方式变了。从下面命令结果可以看出 root 的用户的加密方式为 caching_sha2_passoword, 而 navicat 连接所用的方式为 native_password。

mysql> use mysql

Reading table information for completion of table and column names

You can turn off this feature to get a quicker startup with -A

Database changed
mysql> select host, user, plugin from user;
+-----------+------------------+-----------------------+
| host      | user             | plugin                |
+-----------+------------------+-----------------------+
| %         | root             | mysql_native_password |
| localhost | mysql.infoschema | caching_sha2_password |
| localhost | mysql.session    | caching_sha2_password |
| localhost | mysql.sys        | caching_sha2_password |
| localhost | root             | caching_sha2_password |
+-----------+------------------+-----------------------+
5 rows in set (0.00 sec)

5.3.1 修改密码策略

下面开始修改密码操作,但是直接用 alter 命令改还不行,因为 123456 密太简单,不满足密码策略,查看密码策略命令如下:

mysql> SHOW VARIABLES LIKE 'validate%';

+--------------------------------------+--------+

| Variable_name                        | Value  |
+--------------------------------------+--------+
| validate_password.check_user_name    | ON     |
| validate_password.dictionary_file    |        |
| validate_password.length             | 8      |
| validate_password.mixed_case_count   | 1      |
| validate_password.number_count       | 1      |
| validate_password.policy             | MEDIUM |
| validate_password.special_char_count | 1      |
+--------------------------------------+--------+
7 rows in set (0.01 sec)

需要把 validate_password.check_user_name 改为 OFF,validate_password.length 改为 1,validate_password.policy 改为 LOW。命令如下:

mysql> set global validate_password.check_user_name=0;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password.length=1;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password.policy=0;
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW VARIABLES LIKE 'validate%';

+--------------------------------------+-------+
| Variable_name                        | Value |
+--------------------------------------+-------+
| validate_password.check_user_name    | OFF   |
| validate_password.dictionary_file    |       |
| validate_password.length             | 4     |
| validate_password.mixed_case_count   | 1     |
| validate_password.number_count       | 1     |
| validate_password.policy             | LOW   |
| validate_password.special_char_count | 1     |
+--------------------------------------+-------+
7 rows in set (0.00 sec)

5.3.2 修改密码

密码策略降低要求后才可以把密码改为 123456(本地和远程的都改为 123456)

mysql> alter user'root'@'localhost' IDENTIFIED BY '123456';
Query OK, 0 rows affected (0.01 sec)

mysql> ALTER USER 'root'@'%' IDENTIFIED by '123456';
Query OK, 0 rows affected (0.01 sec)

mysql> ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

5.4 建库 solo

mysql> create database solo;
Query OK, 1 row affected (0.01 sec)

6. solo 项目配置

接下来才是主角:下载 solo 项目源码,编译启动 solo,完成开发环境搭建
注:没有装 git 命令请先用yum -y install git命令安装。

6.1 克隆 solo 项目

使用命令:git clone --recurse-submodules https://gitee.com/b3logos/solo.git(国内通过码云下载较快):

    看你提供的打印信息,应该是已经启动成功了。你现在打开浏览器,通过http://【你的服务器IP】:8080/ 访问看看。

    给你看看我启动 solo 的最后打印信息,跟你的差不多嘛。

    你要先登录,然后就会出现管理的按钮,点进去就可以管理后台了。

    不好意思,之前没理解你说“在后台运行”的意思。用下面这个命令即可:

    nohup mvn jetty:run &

    详情你可以百度 nohup 这个命令。
