linux 安装 nginx

在安装nginx前首先要确认系统中安装了gcc、pcre、zlib、openssl。

举例：查看是否安装了pcre

pcre-config --version

 未安装的情况下安装上面的所有依赖

yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

下面开始安装Nginx:
 

Nginx下载地址：  Index of /download/

1、上传到服务器并解压：

tar -zxvf nginx-1.18.0.tar.gz 

 2、进入nginx-1.8.0文件夹下面执行：

./configure --with-http_ssl_module

Nginx 在configure时的参数：

configure 脚本确定系统所具有一些特性，特别是 nginx 用来处理连接的方法。可以使用 ./configure --help 来查看编译时可选的一些参数设置：

我这里的可选参数有：

 3:然后再执行：

make && make install

4：执行完后查看安装情况：

在 /usr/local下面会多一个nginx的一个文件夹

 进入  /nginx/sbin  下面即可看到nginx 的启动脚本（nginx）

5、启动nginx

./nginx

1：建立软连接：

ln -s /usr/local/nginx/sbin/nginx  /usr/bin

2、以后启动直接在任何目录中运行

nginx即可

设置nginx开机自启：

 第一步：进入到/lib/systemd/system/目录

cd /usr/lib/systemd/system/

vim nginx.service

内容如下：
 

[Unit]
Description=nginx service
After=network.target 
   
[Service] 
Type=forking 
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

[Unit]:服务的说明
Description:描述服务
After:描述服务类别
[Service]服务运行参数的设置
Type=forking是后台运行的形式
ExecStart为服务的具体运行命令
ExecReload为重启命令
ExecStop为停止命令
PrivateTmp=True表示给服务分配独立的临时空间
注意：[Service]的启动、重启、停止命令全部要求使用绝对路径
[Install]运行级别下服务安装的相关设置，可设置为多用户，即系统运行级别为3

保存退出。

第三步：加入开机自启动

systemctl enable nginx

如果不想开机自启动了，可以使用下面的命令取消开机自启动

systemctl disable nginx

第四步：服务的启动/停止/刷新配置文件/查看状态

# systemctl start nginx.service　         启动nginx服务
# systemctl stop nginx.service　          停止服务
# systemctl restart nginx.service　       重新启动服务
# systemctl list-units --type=service     查看所有已启动的服务
# systemctl status nginx.service          查看服务当前状态
# systemctl enable nginx.service          设置开机自启动
# systemctl disable nginx.service         停止开机自启动
