前言
在开局配置 Nginx 时有可能会配置谬误,报各种错误代码。看不懂或者懒得去看这个报错时,其实最简略的形式是卸载并重装咯。明天就带大家一起学习下,如何彻底卸载 nginx 程序。
一、卸载 NGINX
卸载 nginx 程序的具体步骤
1、进行 Nginx 软件
/usr/local/nginx/sbin/nginx -s stop
如果不晓得 nginx 装置门路,能够通过执行 ps 命令找到 nginx 程序的 PID,而后 kill 其 PID
2、查找根下所有名字蕴含 nginx 的文件
find / -name nginx
3、执行命令 rm -rf * 删除 nignx 装置的相干文件
阐明:全局查找往往会查出很多相干文件,然而前缀根本都是雷同,前面不同的局部能够用 * 代替,以便疾速删除~
[root@qll251 ~]# rm -rf /usr/local/sbin/nginx
[root@qll251 ~]# rm -rf /usr/local/nginx
[root@qll251 ~]# rm -rf /usr/src/nginx-1.11.1
[root@qll251 ~]# rm -rf /var/spool/mail/nginx
4、其余设置
如果设置了 Nginx 开机自启动的话,可能还须要上面两步
chkconfig nginx off
rm -rf /etc/init.d/nginx
删除之后,便可重新安装 nginx 了
二、开始装置 NGINX
a、装置所需插件
1、装置 gcc
gcc 是 linux 下的编译器在此不多做解释,感兴趣的小伙伴能够去查一下相干材料,它能够编译 C,C++,Ada,Object C 和 Java 等语言
命令:查看 gcc 版本
gcc -v
个别阿里云的 centOS7 外面是都有的,没有装置的话会提醒命令找不到,
装置命令:
yum -y install gcc
2、pcre、pcre-devel 装置
pcre 是一个 perl 库,包含 perl 兼容的正则表达式库,nginx 的 http 模块应用 pcre 来解析正则表达式,所以须要装置 pcre 库。
装置命令:
yum install -y pcre pcre-devel
3、zlib 装置
zlib 库提供了很多种压缩和解压缩形式 nginx 应用 zlib 对 http 包的内容进行 gzip,所以须要装置
装置命令:
yum install -y zlib zlib-devel
4、装置 openssl
openssl 是 web 平安通信的基石,没有 openssl,能够说咱们的信息都是在裸奔。。。。。。
装置命令:
yum install -y openssl openssl-devel
b、装置 nginx
我的环境是应用 3A 服务器装置的 centos7
1、下载 nginx 安装包
wget http://nginx.org/download/ngi…
2、把压缩包解压到 usr/local/java
tar -zxvf nginx-1.9.9.tar.gz
3、切换到 cd /usr/local/java/nginx-1.9.9/ 上面
执行三个命令:
./configure –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module
make
make install
4、切换到 /usr/local/nginx 装置目录
5、配置 nginx 的配置文件 nginx.conf 文件,次要也就是端口

# deny access to .htaccess files, if Apache's document root

#
#location ~ /\.ht {
# deny all;
#}
}
}
能够依照本人服务器的端口应用状况来进行配置
ESC 键,wq!强制保留并退出
6、启动 nginx 服务
切换目录到 /usr/local/nginx/sbin 上面
启动 nginx 命令:
./nginx
7、拜访你的服务器 IP
显示
阐明装置和配置都没问题 OK 了
8、nginx 常用命令
1. 启动 nginx 命点:./nginx
2. 重启 nginx 命令:./nginx -s reload
- 进行 nginx 命令:./nginx -s stop 或 ./nginx -s quit
- 敞开 nginx 过程:
ps -ef|grep nginx
命令 kill -9 8725 (过程号 下面的) 则敞开 nginx
