二進制編譯安裝nginx並加入systemctl管理服務

1、安裝nginx所需環境

# yum install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel -y

2、安裝nginx

① 下載nginx

# wget -c https://nginx.org/download/nginx-1.12.1.tar.gz

② 解壓

# tar -zxvf nginx-1.17.0.tar.gz # cd nginx-1.17.0

 ③ 使用默認配置

# ./configure

④ 編譯、安裝

# make # make install

⑤ 啓動nginx

# cd /usr/local/nginx/sbin/ # ./nginx 其它命令 # ./nginx -s stop # ./nginx -s quit # ./nginx -s reload

3、加入systemctl管理服務

一、 進入到  /usr/lib/systemd/system 目錄下，編輯文件 nginx.service

# cd /usr/lib/systemd/system # vi nginx.service

二、在nginx.service文件中加入如下代碼

[Unit] Description=nginx 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

 

參數說明：

注意：[Service]的啓動、重啓、中止命令所有要求使用絕對路徑

[Unit]:服務的說明 Description:描述服務 After:描述服務類別 [Service]服務運行參數的設置 Type=forking是後臺運行的形式 ExecStart爲服務的具體運行命令 ExecReload爲重啓命令 ExecStop爲中止命令 PrivateTmp=True表示給服務分配獨立的臨時空間 [Install]運行級別下服務安裝的相關設置，可設置爲多用戶，即系統運行級別爲3

 

三、設置開機啓動

# systemctl enable nginx.service

 

四、取消開機自啓動

# systemctl disable nginx.service

 

五、其餘命令

啓動nginx服務

# systemctl start nginx.service　

查看服務當前狀態

# systemctl status nginx

[root@localhost system]# systemctl status nginx ● nginx.service - The nginx HTTP and reverse proxy server Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled) Active: active (running) since Sat 2019-03-23 07:08:49 CST; 7s ago Process: 18942 ExecStart=/usr/local/nginx/sbin/nginx (code=exited, status=0/SUCCESS) Main PID: 18943 (nginx) CGroup: /system.slice/nginx.service ├─18943 nginx: master process /usr/local/nginx/sbin/nginx └─18944 nginx: worker process Mar 23 07:08:49 localhost.localdomain systemd[1]: Starting The nginx HTTP and reverse proxy server... Mar 23 07:08:49 localhost.localdomain systemd[1]: Started The nginx HTTP and reverse proxy server.

 

 

中止nginx服務

# systemctl stop nginx

 

從新啓動服務

# systemctl restart nginx

 

查看全部已啓動的服務

# systemctl list-units --type=service
