CentOS 6.5 是一个较旧的系统版本,安装 Nginx 需要一些额外的步骤。以下是完整的安装方法:
添加 EPEL 仓库:
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
安装 Nginx:
yum install nginx -y
启动 Nginx 并设置开机启动:
service nginx start
chkconfig nginx on
创建 Nginx 官方仓库文件:
vi /etc/yum.repos.d/nginx.repo
添加以下内容:
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/6/$basearch/
gpgcheck=0
enabled=1
安装 Nginx:
yum install nginx -y
启动 Nginx 并设置开机启动:
service nginx start
chkconfig nginx on
安装编译依赖:
yum groupinstall "Development Tools" -y
yum install pcre-devel zlib-devel openssl-devel -y
下载并解压 Nginx 源代码:
wget http://nginx.org/download/nginx-1.12.2.tar.gz
tar -zxvf nginx-1.12.2.tar.gz
cd nginx-1.12.2
配置和编译:
./configure --prefix=/usr/local/nginx --with-http_ssl_module
make
make install
创建启动脚本:
vi /etc/init.d/nginx
添加以下内容:
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /usr/local/nginx/conf/nginx.conf
# pidfile: /usr/local/nginx/logs/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories
user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
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
}
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6

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 $?

sleep 1

}
reload() {

echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?

}
force_reload() {

}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}

echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
设置权限并添加服务:
chmod +x /etc/init.d/nginx
chkconfig --add nginx
chkconfig nginx on
启动 Nginx:
service nginx start
无论使用哪种方法安装,都可以通过以下命令验证 Nginx 是否正常运行:
curl -I 127.0.0.1
或者在浏览器中访问服务器的 IP 地址,应该能看到 Nginx 的欢迎页面。
CentOS 6.5 默认使用较旧版本的 OpenSSL,如果需要支持 TLS 1.2,可能需要升级 OpenSSL。
如果使用防火墙,需要开放 80 端口:
iptables -I INPUT -p tcp --dport 80 -j ACCEPT
service iptables save
对于生产环境,建议使用官方仓库或源代码编译安装,以获取最新版本和安全更新。
CentOS 6.5 已经结束生命周期(EOL),建议升级到 CentOS 7 或更高版本以获得更好的安全性和支持。
