centos7下安装nginx：CentOS下安装Nginx的操作步骤
centos7下安装nginx：CentOS下安装Nginx的操作步骤[root@localhost ~]#useradd nginx -s /sbin/nologin -M4、编译安装nginx2、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-devel3、上传nginx安装包并解压
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
