实验环境
一台最小化的 CentOS 7.3 虚拟机
A. 源码方式安装Nginx
一、安装Nginx
-
安装Nginx依赖包
yum install -y pcre-devel zlib-devel openssl-devel wget gcc tree vim
Nginx依赖于pcre、zlib、openssl,在编译前配置时如果有问题
可以使用yum方式安装三个包(pcre-devel、zlib-devel、openssl-devel) -
从Nginx官网下载Nginx源码包
wget http://nginx.org/download/nginx-1.12.2.tar.gz
-
解压Nginx源码包到
/root/nginx
,并查看Nginx源文件结构tar -xzvf nginx-1.12.2.tar.gz
-
在
/root/nginx
目录进行编译前配置cd /root/nginx* ./configure --prefix=/usr/local/nginx --with-http_ssl_module
- 在
/root/nginx
目录执行编译安装make && make install
二、启动Nginx
-
进入到安装目录
/usr/local/nginx
,查看目录结构cd /usr/local/nginx pwd ls
-
启动Nginx
/usr/local/nginx/sbin/nginx
-
查看Nginx进程是否启动
ps aux | grep nginx
-
查看Nginx占用的端口号
netstat -tlnp
- 使用本地主机访问虚拟机上的Nginx服务器
如果从本地主机无法访问Nginx,请检查虚拟机防火墙配置
CentOS 关闭SELinux(setenforce 0
)
CentOS6.x 关闭防火墙(service iptables stop
)
CentOS7.x 关闭防火墙(systemctl stop firewalld
)
三、停止Nginx
停止Nginx的三种方式
# 1. 立即停止Nginx服务
/usr/local/nginx/sbin/nginx -s stop
# 2.完成当前任务后停止
/usr/local/nginx/sbin/nginx -s quit
# 3.杀死Nginx进程
killall nginx
四、把Nginx命令添加到环境变量
-
使用软连接将
nginx
链接到/usr/local/sbin
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin ll /usr/local/sbin/ | grep "nginx"
-
显示当前环境变量
PATH
echo $PATH
-
编辑
.bash_profile
文件vim ~/.bash_profile
在
.bash_profile
文件末尾加入以下内容export PATH=$PATH:/usr/local/nginx/sbin
-
引用
.bash_profile
文件source ~/.bash_profile
- 使用
nginx
命令# 启动nginx nginx # 停止nginx nginx -s quit
五、把nginx添加到系统服务
- 创建并编辑文件
/root/service-nginx.sh
#!/bin/sh
#
# filename: service-nginx.sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15
# description: NGINX is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /etc/nginx/nginx.conf
# config: /etc/sysconfig/nginx
# pidfile: /var/run/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
#NGINX_CONF_FILE="/etc/nginx/nginx.conf"
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories
user=`$nginx -V 2>&1 | grep "configure arguments:.*--user=" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
if [ -n "$user" ]; then
if [ -z "`grep $user /etc/passwd`" ]; then
useradd -M -s /bin/nologin $user
fi
options=`$nginx -V 2>&1 | grep 'configure arguments:'`
for opt in $options; do
if [ `echo $opt | grep '.*-temp-path'` ]; then
value=`echo $opt | cut -d "=" -f 2`
if [ ! -d "$value" ]; then
# echo "creating" $value
mkdir -p $value && chown -R $user $value
fi
fi
done
fi
}
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
make_dirs
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
configtest || return $?
stop
sleep 1
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
case "$1" in
start)
rh_status_q && exit 0

rh_status_q || exit 0

rh_status_q || exit 7

rh_status_q || exit 0
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
# END
-
用
/root/service-nginx.sh
替换/etc/init.d/nginx
mv /root/service-nginx.sh /etc/init.d/nginx
-
赋予可执行限权
chmod 755 /etc/init.d/nginx
- 执行
systemctl start nginx
六、源码方式安装nginx,自动化安装脚本
#!/bin/bash
# installation configuration
NGINX_VERSION=1.12.2
NGINX_SRC_PATH=/root
NGINX_BIN_PATH=/usr/local/nginx
# disable firewall
systemctl stop firewalld
setenforce 0
# installation dependence
yum install -y pcre-devel zlib-devel openssl-devel wget gcc
# download nginx source package
cd ${NGINX_SRC_PATH}
wget http://nginx.org/download/nginx-${NGINX_VERSION}.tar.gz
# unzip source package
tar -xzvf nginx-${NGINX_VERSION}.tar.gz
cd ./nginx-${NGINX_VERSION}
# install nginx
./configure --prefix=${NGINX_BIN_PATH} --with-http_ssl_module
make & make install
# start nginx service
cd ${NGINX_BIN_PATH}/sbin
./nginx
# END
B. yum方式安装Nginx
-
安装EPEL
yum install epel-* -y
- 安装nginx
yum install -y nginx
