Linux环境搭建

Posted 2021-02-09 江鸟

 基础环境搭建:yum环境

一:安装wget

[[email protected] ~]# yum install -y wget

二:备份yum配置文件

[[email protected] yum.repos.d]# cd /etc/yum.repos.d/ && mv CentOS-Base.repo CentOS-Base.repo.bak

三:下载Centos-6.repo文件

[[email protected] yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
[[email protected] yum.repos.d]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

[[email protected] yum.repos.d]# ll
total 24
-rw-r--r--. 1 root root 2523 Jun 16  2018 CentOS-Base.repo
-rw-r--r--. 1 root root 1926 Nov 27  2013 CentOS-Base.repo.bak1
-rw-r--r--. 1 root root  638 Nov 27  2013 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root  630 Nov 27  2013 CentOS-Media.repo
-rw-r--r--. 1 root root 3664 Nov 27  2013 CentOS-Vault.repo
-rw-r--r--. 1 root root  664 May 11  2018 epel.repo
四:安装补全软件

[[email protected] yum.repos.d]# yum -y install bash-completion

[[email protected] ~]# yum makecache fast

 

编译安装Ngnix

 

1.1 检查软件安装的系统环境

[[email protected] /]# cat /etc/redhat-release
CentOS release 6.5 (Final)
[[email protected] /]# uname -r
2.6.32-431.el6.x86_64

1.2 安装nginx的依赖包（pcre-devel openssl-devel）（一）

yum install -y pcre-devel openssl-devel

说明：pcre-devel(支持perl nginx 定义了rewrite正则匹配语法是Perl正则语法)

openssl-devel(支持nginx服务访问，以https方式访问)

注：要统一安装路径：/home/data/tools/ 下面

1.3 创建一个虚拟用户来管理nginx进程（二） 
[[email protected] /]# useradd -M -s /sbin/nologin nginxuser

1.4 下载nginx软件（三） 

[[email protected] /]# mkdir -p /home/data/tools && cd /home/data/tools
[[email protected] tools]# wget http://nginx.org/download/nginx-1.15.6.tar.gz

1.4.1 解压要编译安装的软件（四）

(解压软件---配置（./configure）---做菜（编译 make）---上菜（安装 make install）)

[[email protected]ihong tools]# tar xf nginx-1.15.6.tar.gz
[[email protected] tools]# cd nginx-1.15.6/
[[email protected] tools]# ll
total 1005
drwxr-xr-x. 8 1001 1001    1024 Nov  6 21:32 nginx-1.15.6
-rw-r--r--. 1 root root 1025761 Nov  6 23:26 nginx-1.15.6.tar.gz

1.4.2 编译配置（五）

[[email protected] nginx-1.15.6]# ./configure --prefix=/application/nginx-1.15.6 --user=nginxuser --group=nginxuser --with-http_stub_status_module  --with-http_ssl_module

--prefix=PATH    指定安装路径

--user=user          指定软件启动后以什么什么身份运行（属主运行）

--group=group       指定软件启动后以什么什么身份（属组）运行，前提是用户必须存在。

--with-http_stub_status_module    nginx的激活状态信息 

若报错./configure: error: C compiler cc is not found 则安装gcc

[[email protected] nginx-1.15.6]# yum -y install gcc

[[email protected] ~]# whereis gcc

1.4.3  编译安装（五）

[[email protected] nginx-1.15.6]# make

[[email protected] nginx-1.15.6]# make install

1.4.4 安装完成一个软件要做一个软链接（六）
[[email protected] tools]# ln -s /application/nginx-1.15.6 /application/nginx

1.4.5  启动nginx软件程序进行测试
[[email protected] nginx]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.15.6/conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.15.6/conf/nginx.conf test is successful
[[email protected] nginx]# /application/nginx/sbin/nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

[[email protected] ~]# ps -e | grep nginx 查看进程是否启动

[[email protected] ~]# netstat -ltunp 查看活动端口
关闭防火墙[[email protected] nginx-1.15.6]# service iptables stop
