Default /etc/sysctl.conf settings for Mac OS X Snow Leopard?
提问by Mur Quirk
I tried to install PostgreSQL 9.1.2 for Mac OS X 10.6 and it asked me to edit the sysctl.conf file inside the /etc/ directory, so it could use more of the shared memory PostgreSQL was asking for.
我尝试为 Mac OS X 10.6 安装 PostgreSQL 9.1.2，它要求我编辑 /etc/ 目录中的 sysctl.conf 文件，以便它可以使用 PostgreSQL 要求的更多共享内存。
I went ahead and edited the file, saved it, rebooted and then on the login screen I was asked to login as safe boot for some reason, I logged in and internet did not seem to work and the dock menu was laggy.
我继续编辑文件，保存它，重新启动，然后在登录屏幕上，出于某种原因，我被要求以安全启动方式登录，我登录后互联网似乎无法正常工作，并且停靠菜单滞后。
So it was pretty obvious this was happening because of the sysctl.conf file that I edited before the reboot, so I went back into the /etc directory and deleted the sysctl.conf file thinking it would auto-create a new sysctl.conf file with the default settings but that wasn't the case even after a reboot.
所以很明显这是因为我在重启前编辑了 sysctl.conf 文件，所以我回到 /etc 目录并删除了 sysctl.conf 文件，认为它会自动创建一个新的 sysctl.conf 文件使用默认设置，但即使在重新启动后情况也并非如此。
So now I'm pretty much left without a sysctl.conf file, I read the Mac Developer documentation for this file and it didn't say much. I know I probably shouldn't be messing with files that I don't have a clue about but I really wanted to get PostgreSQL working for my local Ruby on Rails development.
所以现在我几乎没有 sysctl.conf 文件，我阅读了这个文件的 Mac 开发人员文档，但它没有说太多。我知道我可能不应该弄乱我不知道的文件，但我真的想让 PostgreSQL 为我的本地 Ruby on Rails 开发工作。

I have Lion myself but I don't think there was anything else in it when I was using Snow Leopard.
我自己也有 Lion，但当我使用 Snow Leopard 时，我认为其中没有其他任何东西。

I suggest you save yourself a lot of headaches and install Postgres using the Homebrewpackage manager.
我建议您省去很多麻烦并使用Homebrew包管理器安装 Postgres 。
The steps, once XCode is installed, are:
安装 XCode 后的步骤是：
Install Homebrew
安装 Homebrew
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
Install Postgres
安装 Postgres
brew update; brew install postgres
Initialize Postgres
初始化 Postgres
initdb /usr/local/var/postgres
Set Postgres to run automatically
设置 Postgres 自动运行
mkdir -p ~/Library/LaunchAgents
cp /usr/local/Cellar/postgresql/9.1.2/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
