nginx是广为流行的轻量级web服务器软件。它开源,短小精悍,简单易用,深受广大互联网企业以及it运维人员所喜爱。很多时候,我们在生产环境基于编译方式安装nginx后,nginx需要手工配置自启动服务,以确保服务器异常宕机后自动重启该服务。以下描述的是基于centos 7下来配置自启动服务,供大家参考。
一、yum 安装方式nginx自启动
当前环境
[root@node142 ~]# more /etc/redhat-release centos linux release 7.2.1511 (core)
查看是否保护nginx rpm包
[root@node142 ~]# rpm -qa|grep nginx nginx-mod-http-geoip-1.12.2-2.el7.x86_64 nginx-1.12.2-2.el7.x86_64 nginx-filesystem-1.12.2-2.el7.noarch nginx-mod-http-xslt-filter-1.12.2-2.el7.x86_64 nginx-mod-stream-1.12.2-2.el7.x86_64 nginx-mod-http-perl-1.12.2-2.el7.x86_64 nginx-mod-http-image-filter-1.12.2-2.el7.x86_64 nginx-all-modules-1.12.2-2.el7.noarch nginx-mod-mail-1.12.2-2.el7.x86_64
查看是否存在相应的服务,如下,有nginx.service
[root@node142 ~]# systemctl list-unit-files |grep nginx nginx.service disabled
将其配置为自动
[root@node142 ~]# systemctl enable nginx.service
查看nginx.service文件
[root@node142 ~]# more /lib/systemd/system/nginx.service [unit] description=the nginx http and reverse proxy server after=network.target remote-fs.target nss-lookup.target [service] type=forking pidfile=/run/nginx.pid # nginx will fail to start if /run/nginx.pid already exists but has the wrong # selinux context. this might happen when running `nginx -t` from the cmdline. # https://bugzilla.redhat.com/show_bug.cgi?id=1268621 execstartpre=/usr/bin/rm -f /run/nginx.pid execstartpre=/usr/sbin/nginx -t execstart=/usr/sbin/nginx execreload=/bin/kill -s hup $mainpid killsignal=sigquit timeoutstopsec=5 killmode=process privatetmp=true [install] wantedby=multi-user.target
上述配置文件中的内容和官网提供的一模一样
二、编译安装后的自启动配置
由于是编译安装,因此,对于这个自启动的脚本我们需要自行配制。
具体则是参考上面的链接或者上面给出的nginx.service文件内容。
然后将其保存为 /lib/systemd/system/nginx.service。
看下面的例子
# more /etc/redhat-release centos linux release 7.4.1708 (core) # ps -ef|grep nginx root 10092 10014 0 16:23 pts/0 00:00:00 grep --color=auto nginx root 20791 1 0 mar20 ? 00:00:00 nginx: master process ./sbin/nginx -c /u01/app/nginx/nginx.conf nobody 20792 20791 0 mar20 ? 00:00:44 nginx: worker process nobody 20793 20791 0 mar20 ? 00:00:42 nginx: worker process nobody 20794 20791 0 mar20 ? 00:00:50 nginx: worker process nobody 20795 20791 0 mar20 ? 00:00:44 nginx: worker process nobody 20796 20791 0 mar20 ? 00:00:43 nginx: worker process nobody 20797 20791 0 mar20 ? 00:00:43 nginx: worker process nobody 20798 20791 0 mar20 ? 00:00:37 nginx: worker process nobody 20799 20791 0 mar20 ? 00:00:48 nginx: worker process nobody 20800 20791 0 mar20 ? 00:00:04 nginx: cache manager process #
无相应的rpm包,如下查询,此处为编译安装
# rpm -qa|grep nginx
也没有添加相应的自启动服务
# systemctl list-unit-files |grep nginx
nginx版本
# /u01/app/nginx/sbin/nginx -v nginx version: nginx/1.8.1
获取nginx编译模块,然后查看诸如pid,二进制位置并记录以便修改启动文件
# /u01/app/nginx/sbin/nginx -v nginx version: nginx/1.8.1 built by gcc 4.8.5 20150623 (red hat 4.8.5-16) (gcc) built with openssl 1.0.2k-fips 26 jan 2017 tls sni support enabled configure arguments: --prefix=/u01/app/nginx --sbin-path=/u01/app/nginx/sbin/nginx --conf-path=/u01/app/nginx/nginx.conf --error-log-path=/u01/app/nginx/log/error.log --http-log-path=/u01/app/nginx/log/access.log --pid-path=/u01/app/nginx/nginx.pid --lock-path=/u01/app/nginx/nginx.lock --http-client-body-temp-path=/u01/app/nginx/client_temp --http-proxy-temp-path=/u01/app/nginx/proxy_temp --http-fastcgi-temp-path=/u01/app/nginx/fastcgi_temp --http-uwsgi-temp-path=/u01/app/nginx/uwsgi_temp --http-scgi-temp-path=/u01/app/nginx/scgi_temp --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-mail --with-mail_ssl_module --with-file-aio --with-http_spdy_module --with-ipv6
下面我们生成一个新的nginx.service文件
# vim /lib/systemd/system/nginx.service [unit] description=the nginx http and reverse proxy server after=syslog.target network.target remote-fs.target nss-lookup.target [service] type=forking pidfile=/u01/app/nginx/nginx.pid execstartpre=/u01/app/nginx/sbin/nginx -t execstart=/u01/app/nginx/sbin/nginx execreload=/bin/kill -s hup $mainpid execstop=/bin/kill -s quit $mainpid privatetmp=true [install] wantedby=multi-user.target
下面我们先手工停止nginx
# /u01/app/nginx/sbin/nginx -s stop
配置自启动
# systemctl enable nginx.service
使用systemctl工具启动nginx服务
# systemctl start nginx.service # systemctl status nginx.service ● 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 thu 2018-03-29 16:37:47 cst; 6s ago process: 10588 execstart=/u01/app/nginx/sbin/nginx (code=exited, status=0/success) process: 10586 execstartpre=/u01/app/nginx/sbin/nginx -t (code=exited, status=0/success) main pid: 10590 (nginx) cgroup: /system.slice/nginx.service ├─10590 nginx: master process /u01/app/nginx/sbin/nginx ├─10591 nginx: worker process # author : leshami ├─10592 nginx: worker process # blog : https://blog.csdn.net/leshami ├─10593 nginx: worker process ├─10594 nginx: worker process ├─10595 nginx: worker process ├─10596 nginx: worker process ├─10597 nginx: worker process ├─10598 nginx: worker process ├─10599 nginx: cache manager process └─10600 nginx: cache loader process mar 29 16:37:47 ydq-std systemd[1]: starting the nginx http and reverse proxy server... mar 29 16:37:47 ydq-std nginx[10586]: nginx: the configuration file /u01/app/nginx/nginx.conf syntax is ok mar 29 16:37:47 ydq-std nginx[10586]: nginx: configuration file /u01/app/nginx/nginx.conf test is successful mar 29 16:37:47 ydq-std systemd[1]: started the nginx http and reverse proxy server.
