Linux系统安装软件四种方式

Linux系统安装软件四种方式：

• 绿色安装
• yum安装
• rpm安装
• 源码安装

1. 绿色安装

这种方式最简便，一般提供Compressed Archive压缩文档包，如Java软件的压缩文档包，只需要解压、设置环境变量即可直接使用。

# 下载软件
https://www.oracle.com/java/technologies/downloads/

# 新建java软件存放路径
mkdir /opt/java

# 解压
tar -xvf jdk-21_linux-x64_bin.tar.gz -C /opt/java

# 设置环境变量
vim /etc/profile.d/java.sh

JAVA_HOME=/opt/java/jdk-21.0.1/
CLASSPATH=.:$JAVA_HOME/lib
PATH=JAVA_HOME/bin:$PATH
export JAVA_HOME CLASSPATH PATH

# 加载环境变量
source /etc/profile.d/java.sh

# 检验java环境是否配置好
java

2. yum安装

• 前提条件是有网络
• 需要安装的软件及版本，yum源里刚好有。

# 搜索redis源
yum search redis

# 查看redis详细信息
yum info redis

# 安装redis软件
yum -y install redis

# 查看redis状态
systemctl status redis

# 设置开机自启
systemctl enable redis

# 启动redis服务
systemctl start redis

3. rpm安装

需要的软件及版本，只提供了rpm包

3.1 rpm常用命令

# 安装一个包
rpm -ivh 包名

# 升级一个包
rpm -Uvh 包名

# 查询包是否安装
rpm -q 包名

# 查询安装包详情信息
rpm -qi 包名

# 列出服务器上的一个文件属于哪个rpm包
rpm -qf 文件名

# 列出所有安装的rpm包
rpm -qa

# 卸载包
rpm -e 包名

[root@centos ~]# rpm --help
Usage: rpm [OPTION...]

# 安装java的jdk
rpm -ivh jdk-21_linux-x64_bin.rpm

# 查看安装的jdk
rpm -qa | grep "jdk"

# 忽略依赖关系强制卸载jdk
rpm -evh --nodeps jdk-21-21.0.1-12.x86_64

4. 源码安装

软件给的是C语言的源代码，需要编译成二进制，再安装。

Linux下安装软件，大型软件docker、oracle一般放/opt目录下；/usr目录一般由软件包管理器（yum、apt）来管理；/usr/local是用户级程序目录，/usr/local/src是用户级存放目录。

以安装nginx为例

# 安装依赖
yum install -y gcc pcre-devel openssl-devel

4.1 执行configure脚本

./configure [option…]

• 通过选项传递参数，指定安装路径、启用特性等；执行时会参考用户的指定以及Makefile.in文件生成Makefile
• 检查依赖到的外部环境，如依赖的软件包

tar -xvf nginx-1.25.3.tar.gz

cd nginx-1.25.3

./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --user=nginx --group=nginx

选项说明：

4.2 编译、安装

# 编译
make 

• make 根据Makefile文件，会检测依赖的环境，进行构建应用程序

4.3 安装

# 安装
make install

• make install 复制文件到相应路径

4.4 操作nginx

# 启动服务
/usr/local/nginx/sbin/nginx

# 重新加载配置文件
/usr/local/nginx/sbin/nginx -s reload

# 设置软连接
ln -s /usr/local/nginx/sbin/nginx  /usr/local/sbin/

# 强制停止
nginx -s stop

# 安全退出
nginx -s quit

# 查看进程
ps -ef | grep nginx

# 测试
curl 127.0.0.1

4.5 创建服务器

编写配置文件

# 编写配置文件
vi /usr/lib/systemd/system/nginx.service

# 写入这些信息
[Unit]
Description=nginx
After=network.target

[Service]
Type=forking
ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true

[Install]
WantedBy=multi-user.target

使用systemctl管理nginx服务

systemctl enable nginx

systemctl strat nginx

systemctl status nginx
