Ubuntu/Linux安装JDK、Mysql、Redis、Rabbitmq、Nginx 并设置开机自启动

前言

1、Ubuntu安装版本为20.04

2、文中安装包也可以从网盘下载

链接：https://pan.baidu.com/s/1YAXhSByi0fQULPR6lV3yGg

提取码：ubun

3、相关查看命令

# 查看所有服务列表
ubuntu@ubuntu:~/lyqc/mysql$ systemctl list-unit-files

# 利用grep过滤指定服务（如下：查看mysqld服务开机自启动设置）
ubuntu@ubuntu:~/lyqc/mysql$ systemctl list-unit-files | grep mysql

# 查看系统中某个文件或文件夹
ubuntu@ubuntu:~/lyqc/mysql$ find / -name 'my.cnf'

1、JDK安装

1.1 jdk下载

先去Oracle官网下载jdk，本人使用版本为jdk-8u351

1.2 jdk上传并解压

将上面的jdk上传到服务器，使用下面命令解压

sudo tar -zxvf jdk-8u351-linux-x64.tar.gz

命令参数解释

1.3 jdk安装

1.3.1 获取jdk安装路径(使用pwd命令)

ubuntu@ubuntu:~/lyqc/jdk1.8.0_351$ pwd
/home/ubuntu/lyqc/jdk1.8.0_351

将上面的路径记录下来，后面需要配置环境

1.3.2 配置环境变量

vim ~/.bashrc   #按键盘上的i进入insert模式

在文件的末尾添加下面内容

#set oracle jdk environment
export JAVA_HOME=/home/ubuntu/lyqc/jdk1.8.0_351  ## 这里要注意目录要换成自己解压的jdk目录
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

按 Esc键盘，输入 :wq 保存并退出

通过输入一下命令，使配置生效

source ~/.bashrc 

最后输入 java -version 测试下是否安装成功

ubuntu@ubuntu:~/lyqc/jdk1.8.0_351$ java -version
java version "1.8.0_351"
Java(TM) SE Runtime Environment (build 1.8.0_351-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.351-b10, mixed mode)
ubuntu@ubuntu:~/lyqc/jdk1.8.0_351$ 

2、Mysql安装

2.1 mysql下载

进入mysql官网下载对应的版本

本人下载的版本是5.7.36

2.2 mysql上传并解压

使用命令mkdir mysql创建mysql目录，并解压到mysql目录下

tar -xvf mysql-server_5.7.36-1ubuntu18.04_amd64.deb-bundle.tar -C mysql/

查看

ubuntu@ubuntu:~/lyqc$ cd mysql
ubuntu@ubuntu:~/lyqc/mysql$ ls
libmysqlclient20_5.7.36-1ubuntu18.04_amd64.deb    mysql-common_5.7.36-1ubuntu18.04_amd64.deb            mysql-community-test_5.7.36-1ubuntu18.04_amd64.deb
libmysqlclient-dev_5.7.36-1ubuntu18.04_amd64.deb  mysql-community-client_5.7.36-1ubuntu18.04_amd64.deb  mysql-server_5.7.36-1ubuntu18.04_amd64.deb
libmysqld-dev_5.7.36-1ubuntu18.04_amd64.deb       mysql-community-server_5.7.36-1ubuntu18.04_amd64.deb  mysql-testsuite_5.7.36-1ubuntu18.04_amd64.deb
mysql-client_5.7.36-1ubuntu18.04_amd64.deb        mysql-community-source_5.7.36-1ubuntu18.04_amd64.deb
ubuntu@ubuntu:~/lyqc/mysql$ 

2.3 mysql安装

2.3.1 使用dpkg -i命令顺序安装

sudo dpkg -i mysql-common_5.7.36-1ubuntu18.04_amd64.deb 
sudo dpkg -i libmysqlclient20_5.7.36-1ubuntu18.04_amd64.deb 
sudo dpkg -i libmysqlclient-dev_5.7.36-1ubuntu18.04_amd64.deb 
sudo dpkg -i libmysqld-dev_5.7.36-1ubuntu18.04_amd64.deb 
sudo dpkg -i mysql-community-server_5.7.36-1ubuntu18.04_amd64.deb 

在安装mysql server这个包的时候 会报依赖错误 暂时先不管

ubuntu@ubuntu:~/lyqc/mysql$ sudo dpkg -i mysql-community-server_5.7.36-1ubuntu18.04_amd64.deb 
Selecting previously unselected package mysql-community-server.
(Reading database ... 74128 files and directories currently installed.)

接着我们安装mysql-client 然后此时你会发现 又提示缺少mysql-community-client这个依赖包 继续装

ubuntu@ubuntu:~/lyqc/mysql$ sudo dpkg -i mysql-client_5.7.36-1ubuntu18.04_amd64.deb 
Selecting previously unselected package mysql-client.
(Reading database ... 74290 files and directories currently installed.)

再安装mysql-community-client，发现又缺少libmecab这个包了

ubuntu@ubuntu:~/lyqc/mysql$ sudo dpkg -i mysql-community-client_5.7.36-1ubuntu18.04_amd64.deb 
Selecting previously unselected package mysql-community-client.

接下来使用命令 apt –fix-broken install 自动解决依赖问题，选择y同意

ubuntu@ubuntu:~/lyqc/mysql$ sudo apt --fix-broken install

2.3.2 在接下来的弹框中输入你的mysql密码就可以了

2.3.3 输入完两次密码后，mysql的安装就完成了，验证一下

ubuntu@ubuntu:~/lyqc/mysql$ mysql -u root -p123456
mysql: [Warning] Using a password on the command line interface can be insecure.

mysql> 

2.4 mysql远程连接

2.4.1 首先 进入mysql库 查看user表

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> 
mysql> select User,Host from user;
+---------------+-----------+
| User          | Host      |
+---------------+-----------+
| mysql.session | localhost |
| mysql.sys     | localhost |
| root          | localhost |
+---------------+-----------+
3 rows in set (0.00 sec)

mysql> 

发现root的Host是localhost 这里需要修改为 ‘%’

%表示哪里都可以访问

mysql> update user set host = '%' where user = 'root'; 
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

mysql> select User,Host from user;
+---------------+-----------+
| User          | Host      |
+---------------+-----------+
| root          | %         |
| mysql.session | localhost |
| mysql.sys     | localhost |
+---------------+-----------+
3 rows in set (0.00 sec)

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

mysql> 

2.4.2 接下来还需要修改mysql的配置文件

sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

将bind-address修改为0.0.0.0（表示不限制ip）

保存退出 重启mysql服务

systemctl restart mysql

2.5 mysql设置开机自启动

2.5.1 创建一个服务单元

vi /lib/systemd/system/mysql.service

2.5.2 单元内容

[Unit]
Description=mysql
After=network.target

[Service]
Type=forking
ExecStart=service mysql start
ExecReload=service mysql restart
ExecStop=service mysql stop
PrivateTmp=true

[Install]
WantedBy=multi-user.target

2.5.3 重新加载服务并设置开机自启动

# 重新加载服务
systemctl daemon-reload
# 设置开机自启动
systemctl enable mysql.service

3、Redis安装

3.1 redis环境配置

安装gcc

 sudo apt-get install -y gcc
 sudo apt-get install -y g++
 sudo apt-get install -y gcc automake autoconf libtool make
 sudo apt-get install pkg-config

3.2 redis下载

进入redis官网下载对应的版本

3.3 redis上传并解压

使用命令mkdir redis创建redis目录，并解压到redis目录下

tar -zxvf redis-6.2.6.tar.gz

ubuntu@ubuntu:~/lyqc/redis$ ls
bin  redis-6.2.6  redis-6.2.6.tar.gz
ubuntu@ubuntu:~/lyqc/redis$ 

3.4 redis安装

3.4.1 进入到redis-6.2.6目录，查看是否存在Makefile文件，存在则直接make编译

ubuntu@ubuntu:~/lyqc/redis/redis-6.2.6$ ls
00-RELEASENOTES  CONDUCT       COPYING  INSTALL   MANIFESTO  redis.conf  runtest-cluster    runtest-sentinel  src    TLS.md
BUGS             CONTRIBUTING  deps     Makefile   README.md  runtest     runtest-moduleapi  sentinel.conf     tests  utils
ubuntu@ubuntu:~/lyqc/redis/redis-6.2.6$ 
ubuntu@ubuntu:~/lyqc/redis/redis-6.2.6$ 
ubuntu@ubuntu:~/lyqc/redis/redis-6.2.6$ sudo make

安装时间稍长 如果出现以下信息则表示编译成功

Hint: It's a good idea to run 'make test' ;) 

3.4.2 安装编译后的redis放在指定目录下 会在指定目录生成bin目录

make install PREFIX=/home/ubuntu/lyqc/redis

出现以下信息表示安装成功

Hint: It's a good idea to run 'make test' ;)

    INSTALL redis-server
    INSTALL redis-benchmark
    INSTALL redis-cli

3.4.3 redis启动

进入bin目录执行 ./redis-server 即可启动redis

ubuntu@ubuntu:~/lyqc/redis/bin$ ls
redis-benchmark  redis-check-aof  redis-check-rdb  redis-cli  redis.conf  redis-sentinel  redis-server
ubuntu@ubuntu:~/lyqc/redis/bin$ ./redis-server

为了让redis后台启动 我们需要修改bin下面的redis.conf 将 daemonize no -> daemonize yes (no->yes 启动方式由前台启动改为后台启动)

vim redis.conf

修改bind ip地址为0.0.0.0 以便远程连接

输入 ESC -> :wq -> Enter 保存并退出

3.5 redis开机自启动

3.5.1 创建一个服务单元

vi /lib/systemd/system/redis.service

3.5.2 单元内容

[Unit]
Description=redis
After=network.target
 
[Service]
Type=forking
ExecStart=/home/ubuntu/lyqc/redis/bin/redis-server /home/ubuntu/lyqc/redis/bin/redis.conf
ExecStop=/home/ubuntu/lyqc/redis/bin/redis-cli shutdown
PrivateTmp=true
 
[Install]
WantedBy=multi-user.target

3.5.3 重新加载并设置开机自启动

# 重新加载服务
systemctl daemon-reload
# 设置开机自启动
systemctl enable redis.service

本人设置了之后并没有生效 使用了下面的方法实现了自启动

# 1、建立redis文件夹
mkdir /etc/redis
# 2、把redis源码文件中redis.conf复制到/etc/redis/目录下
cp /home/ubuntu/lyqc/redis/bin/redis.conf /etc/redis/6379.conf
# 3、拷贝redis源码中初始化文件redis_init_script到/etc/init.d/redis
cp /home/ubuntu/lyqc/redis/redis-6.2.6/utils/redis_init_script /etc/init.d/redis
# 4、修改/etc/init.d/redis配置文件中EXEC和CLIEXEC与自己路径一致
EXEC=/home/ubuntu/lyqc/redis/bin/redis-server
CLIEXEC=/home/ubuntu/lyqc/redis/bin/redis-cli
# 5、加入开机自启项
chkconfig redis on
# 6、7、然后 vi /etc/rc.d/rc.local 在文件rc.local中添加启动命令 （保证命令可运行）
vi /etc/rc.d/rc.local
/etc/init.d/redis start

4、Rabbitmq安装

rabbitmq使用的语言是erlang 所以需要先安装erlang

4.1 erlang下载

官网地址下载对应版本

下载的时候要注意erlang版本和rabbitmq版本对应 可通过地址查看对应关系

4.2 erlang安装

执行安装命令

sudo dpkg -i esl-erlang_25.3-1~ubuntu~focal_amd64.deb

命令执行后会出现缺少软件包的错误，可以去地址：https://packages.ubuntu.com/下载对应的安装包 需要注意 ubunut版本20.04对应的focal

然后把所有下载好的deb包放在一起 执行命令安装

sudo dpkg -i *.deb

本人执行的是：

sudo apt-get install libwxbase3.0-0v5
# 按照上面命令执行后的提示 执行下面命令
sudo apt --fix-broken install

执行erl命令查看erl是否安装成功

ubuntu@ubuntu:~/lyqc/rabbitmq$ erl
Erlang/OTP 25 [erts-13.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [jit:ns]

Eshell V13.2  (abort with ^G)
1> halt().
# halt(). 是erlang的控制台中断语句 注意最后的点号
ubuntu@ubuntu:~/lyqc/rabbitmq$ 

4.3 rabbitmq 下载

进入官网下载对应版本的rabbitmq

本人官网打不开，用的下载地址是： https://packagecloud.io/rabbitmq/rabbitmq-server?filter=debs&page=4

下载的版本是rabbitmq-server_3.11.19-1_all.deb

服务器版本不同，下载的rabbitmq描述名称是不同的

4.4 rabbitmq安装

# 安装rabbitmq包
sudo dpkg -i rabbitmq-server_3.11.19-1_all.deb
# 设置管理员用户名密码
sudo rabbitmqctl add_user root root
# 授予管理员的访问权限
sudo rabbitmqctl set_user_tags root administrator
