在一台最小化安装的CentOS 7系统虚拟机中源码安装并且配置Nginx服务器,以下是详细的安装配置步骤。
一、安装nginx 1.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) 1 2.从Nginx官网下载Nginx源码包(也可以使用新一点的nginx 1.15.2版本,本文使用稳定点的1.12.2版本。) 如果使用nginx 1.15.2版本: wget http://nginx.org/download/nginx-1.15.2.tar.gz 本文使用的是nginx 1.12.2版本: wget http://nginx.org/download/nginx-1.12.2.tar.gz
3.解压Nginx源码包到/root/nginx,并查看Nginx源文件结构(如果下载的是nginx 1.15.2版本则下面相应改为nginx 1.15.2。) tar -xzvf nginx-1.12.2.tar.gz
4.在/root/nginx目录进行编译前配置: cd /root/nginx* ./configure --prefix=/usr/local/nginx --with-http_ssl_module
5.在/root/nginx目录执行编译安装: make && make install
二、启动nginx 1.关闭防火墙: setenforce 0 systemctl stop firewalld systemctl disable firewalld
2.进入到安装目录/usr/local/nginx,查看目录结构: cd /usr/local/nginx pwd ls
3.启动Nginx: /usr/local/nginx/sbin/nginx 4.查看Nginx进程是否启动: ps aux | grep nginx
5.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。
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 1.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"
2.显示当前环境变量PATH: echo $PATH 3.编辑.bash_profile文件: vim ~/.bash_profile 4.在.bash_profile文件末尾加入以下内容: export PATH=$PATH:/usr/local/nginx/sbin
5.引用.bash_profile文件: source ~/.bash_profile 6.使用nginx命令: # 启动nginx nginx # 停止nginx nginx -s quit
五、把nginx命令添加到系统服务 1.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 $1 ;; stop) rh_status_q || exit 0 $1 ;; restart|configtest) $1 ;; reload) rh_status_q || exit 7 $1 ;; force-reload) force_reload ;; status) rh_status ;; condrestart|try-restart) rh_status_q || exit 0 ;; *) echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}" exit 2 esac # END 2.用/root/service-nginx.sh替换/etc/init.d/nginx: mv /root/service-nginx.sh /etc/init.d/nginx 3.赋予可执行限权: chmod 755 /etc/init.d/nginx 4.执行: systemctl start nginx
附: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
