CentOS下安装Nginx的操作步骤

CentOS下安装Nginx步骤如下

1、下载nginx安装包

http://nginx.org/en/download.html

下载nginx-1.14.2稳定版本

2、yum安装nginx基础依赖包pcre-devel,pcre,openssl,openssl-devel

[root@localhost ~]# yum install -y pcre pcre-devel openssl openssl-devel

3、上传nginx安装包并解压

4、编译安装nginx

[root@localhost ~]#useradd nginx -s /sbin/nologin -M

[root@localhost ~]# cd /opt/nginx-1.14.2

[root@localhost nginx-1.14.2]# ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx-1.14.2/ --with-http_stub_status_module --with-http_ssl_module

[root@localhost nginx-1.14.2]# make &&make install

5、创建软链ln -s /usr/local/nginx-1.14.2 /usr/local/nginx

6、检查安装结果

nginx -V # 可以查看编译选项

nginx -t # 检查配置文件语法

启动nginx

关闭nginx

[root@localhost sbin]# pwd

/usr/local/nginx/sbin

[root@localhost sbin]# ./nginx

[root@localhost sbin]# ./nginx -s stop

7、设置nginx开机自启动

vim /etc/init.d/nginx #在linux系统的/etc/init.d/目录下创建nginx文件

在脚本中添加如下命令:

[root@localhost init.d]# cat nginx

#!/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

nginx_config=/usr/local/nginx/conf/nginx.conf

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

chmod a+x /etc/init.d/nginx #设置文件的执行权限

然后,就可以通过该脚本对nginx服务进行管理了:

/etc/init.d/nginx start

/etc/init.d/nginx stop

使用chkconfig进行管理

上面的方法完成了用脚本管理nginx服务的功能,比如要设置nginx开机启动等。这时可以使用chkconfig来设置。

先将nginx服务加入chkconfig管理列表:

chkconfig --add /etc/init.d/nginx

加完这个之后,就可以使用service对nginx进行启动,重启等操作了。

service nginx start

service nginx stop

设置开机自启动:

chkconfig nginx on
