yum 安装nginx(配置开机启动)

yum install -y nginx

通过yum安装的时候提示下面的错误

[root@localhost yum.repos.d]# yum install nginx
已加载插件：fastestmirror, langpacks
Loading mirror speeds from cached hostfile
没有可用软件包 nginx。
错误：无须任何处理

需要添加nginx的源

[root@localhost yum.repos.d]# rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

该命令执行之后，会在/etc/yum.respos.d下面多出一个nginx.repo

[root@localhost yum.repos.d]# ll
总用量 40
-rw-r--r--. 1 root root 1572 12月  1 2016 CentOS-Base.repo
-rw-r--r--. 1 root root 1572 12月  1 2016 CentOS-Base.repo.backup
-rw-r--r--. 1 root root 1664 10月 24 10:36 CentOS-Base.repo.bak
-rw-r--r--. 1 root root 1309 8月  30 2017 CentOS-CR.repo
-rw-r--r--. 1 root root  649 8月  30 2017 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root  314 8月  30 2017 CentOS-fasttrack.repo
-rw-r--r--. 1 root root  630 8月  30 2017 CentOS-Media.repo
-rw-r--r--. 1 root root 1331 8月  30 2017 CentOS-Sources.repo
-rw-r--r--. 1 root root 3830 8月  30 2017 CentOS-Vault.repo
-rw-r--r--. 1 root root  113 7月  15 2014 nginx.repo

然后再执行安装命令

yum install -y nginx

安装之后，可以查看nginx的默认安装目录

[root@localhost yum.repos.d]# whereis nginx
nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz
[root@localhost yum.repos.d]# pwd
/etc/yum.repos.d

以下是Nginx的默认路径：

(1) Nginx配置路径：/etc/nginx/

(2) PID目录：/var/run/nginx.pid

(3) 错误日志：/var/log/nginx/error.log

(4) 访问日志：/var/log/nginx/access.log

(5) 默认站点目录：/usr/share/nginx/html

事实上，只需知道Nginx配置路径，其他路径均可在/etc/nginx/nginx.conf 以及/etc/nginx/conf.d/default.conf 中查询到

nginx相关的验证命令及启动命令

[root@localhost yum.repos.d]# nginx
[root@localhost yum.repos.d]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@localhost yum.repos.d]# nginx -s reload             

nginx   启动

nginx -t  测试命令

nginx -s relaod 修改nginx.conf之后，可以重载

有些源经常失效，下面放上最新链接  直接去里面下载  rpm  -Uvh 下载的rpm  就好了

http://nginx.org/packages/centos/7/noarch/RPMS/（源链接）

 最新安装   rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

 

 配置开机启动

 

进入到/etc/init.d/目录下，创建文件nginx
cd /etc/init.d/
vim nginx

nginx文件具体配置信息如下：
#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15
# description: Nginx is a high-performance web and proxy server.
#              It has a lot of features, but it's not for everyone.
# processname: nginx
# pidfile: /var/run/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf

nginxd=/usr/local/nginx/sbin/nginx        # 你的nginx真实启动文件路径
nginx_config=/usr/local/nginx/conf/nginx.conf    # nginx相关配置文件路径
nginx_pid=/var/run/nginx.pid
RETVAL=0
prog="nginx"
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
    if [ -e $nginx_pid ];then
       echo "nginx already running...."
   exit 1
    fi
       echo -n $"Starting $prog: "
       daemon $nginxd -c ${nginx_config}
   RETVAL=$?
   echo
       [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
   return $RETVAL
}

# Stop nginx daemons functions.
stop() {
    echo -n $"Stopping $prog: "
    killproc $nginxd
    RETVAL=$?
    echo
    [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid
}

# reload nginx service functions.
reload() {
    echo -n $"Reloading $prog: "
    #kill -HUP `cat ${nginx_pid}`
    killproc $nginxd -HUP
    RETVAL=$?
    echo
}

# See how we were called.
    case "$1" in
start)
    start
    ;;
stop)
    stop
    ;;
reload)
    reload
    ;;
restart)
    stop
    start
    ;;
status)
    status $prog
    RETVAL=$?
    ;;
*)
    echo $"Usage: $prog {start|stop|restart|reload|status|help}"
    exit 1
esac
exit $RETVAL

保存nginx文件并赋权
chmod 755 nginx
将nginx权限设置为自己可以read、write、exec，其他用户只能有read、exec权限，没有write权限

为nginx加上service相关命令权限
chkconfig --add nginx
chkconfig nginx on
开启nginx的service命令

校验nginx的service命令是否成功
service nginx start 执行不报错表示nginx已经启动

重启centos服务器再次验证是否nginx已经启动
重启之前service nginx stop停止nginx服务，之后执行reboot，开机之后执行ps aux | grep nginx如果后台显示nginx已经启动，那么表示nginx的安装和开机自启动已经成功配置
