Linux lamp一键安装问题

1.MySQL php 安装依赖库出错
解决：   
yum clean all
rpm --rebuilddb

2.status_module on提示73行报错
解决：lamp安装包/ src/ 安装包名称：
./configure --prefix=/usr/local/nginx --with-http_stub_status_module
make
cp /root/lnmp1.3-full/src/nginx-1.10.0/objs/nginx /usr/local/nginx/sbin/
覆盖

3.nginx启动缺少 pid
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
cd /usr/local/nginx
cd logs ls
access.log  error.log  nginx.pid

4.Linux 禁ping和开启ping操作
# echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
如果要恢复，只要：
# echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all
即可，挺方便，不要去专门使用ipchains或者iptables了。
或者用以下方法也可以，异曲同工
以root进入Linux系统，然后编辑文件icmp_echo_ignore_all
vi /proc/sys/net/ipv4/icmp_echo_ignore_all
将其值改为1后为禁止PING
将其值改为0后为解除禁止PING

5.ssh安装
[root@localhost ~]# yum install openssh-server
这样就可以安装好ssh-server了。
检验SSH是否安装好了，可以用下面的命令：
[linuxidc@localhost ~]$ ssh -version
OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010
Bad escape character 'rsion'.
如果显示上面的信息，说明安装好了SSH。

6.服务端设置
先 vi /etc/ssh/sshd_config ，打开这两个配置：
RSAAuthentication yes
PubkeyAuthentication yes
如果想禁止密码登陆，设置：
PasswordAuthentication no
将客户端发来的公钥追加到~/.ssh/authorized_keys下面（公钥生成见下文）：
cat key.pub >> ~/.ssh/authorized_keys
echo >> ~/.ssh/authorized_keys  #输入一个回车，以便下次追加从新的一行开始
然后重启sshd服务：
#systemctl restart sshd.service
service sshd restart
解决办法是需要安装openssl以及ncurses组件
yum install -y openssl*
yum -y install ncurses-devel
